Federal rules fix when a truck driver must stop and assign the parking to nobody — 313,000 spaces nationally and 98 percent of drivers reported trouble in 2019

What is happening?

The last federal count of truck parking in the United States found about 313,000 spaces nationally, and 98 percent of the 11,696 drivers who answered the accompanying survey reported problems finding safe parking. That count is the 2018 through 2019 cycle of the Jason's Law survey, published by the Federal Highway Administration on 2020-12-01. As of 2026-08-08 it is still the most recent national figure that exists.

Of those spaces, 40,000 sat at public rest areas and 273,000 at private truck stops — private capacity was 87.2 percent of the national total as of 2019. Between 2014 and 2019 public supply grew 6 percent and private supply 11 percent, while the shortage spread beyond the mid-Atlantic, Chicago and California areas identified in 2014 to the full I-95 corridor, Pacific corridors and the states surrounding Chicago.

Federal law compels the stop. 49 CFR 395 fixes an 11-hour driving limit after 10 consecutive hours off duty, a 14-hour on-duty window that off-duty time does not extend, and a 30-minute break after 8 cumulative hours of driving; 49 CFR 395.8 requires an electronic logging device that records driving time to the minute and to the location. Federal law does not supply the place to stop. What it supplies instead is a survey duty, a national priority label, a state assessment duty and funding eligibility — and the joint FHWA and FMCSA memorandum of 2025-06-27 that gathers all four into one document states that its contents do not have the force and effect of law and are not meant to bind the States or the public in any way.

Money has begun to move. Three federal programs awarded nearly USD 752 million to truck parking projects between 2022 and 2024, USD 200 million was enacted for truck parking in the FY2026 appropriations and reported on 2026-02-04, and USD 61.7 million in awards to four states was announced on 2026-07-08. Against a median public construction cost of USD 93,500 per space reported in April 2025, none of these sums is sized to a deficit that no published source has ever measured.

Whose problem is this?

The 2025 industry survey ranks truck parking second among truck drivers and second among owner-operators, and ninth among motor carriers. The party paying the cost is not the party that buys the equipment or writes the freight contract.

Where does this problem end?

The boundary matters here because nobody disputes that more truck parking is needed and nothing obliges anyone to supply it. That is a different shape of problem from one where the remedy itself is contested.

What is the state now, and what should it be?

Now

Needs a new measurementthe target state: no source opened here states how many truck parking spaces the country needs. The FHWA Truck Parking Development Handbook, updated March 2026, teaches practitioners how to estimate demand at a single site and carries no national figure. Jason's Law asked for a survey, a traffic volume assessment and a system of metrics, and did not ask for a needs estimate. Every dollar figure in the table above is therefore a numerator without a denominator, and no reader can say what share of the problem any of them closes.

How big is it?

Between about 1,676,000 and about 2,190,000 drivers. The chain runs three steps. Heavy and tractor-trailer truck drivers employed in the United States numbered 2,235,100 as of 2024. Among the 11,696 drivers who answered the 2019 federal survey, 75 percent reported problems finding safe parking at least once a week and 98 percent reported problems at some frequency. Applying the lower incidence gives 1,676,325 and the higher gives 2,190,398.

The two bounds bracket a definitional choice rather than measurement uncertainty. The low bound answers how many drivers meet this at least weekly and the high bound answers how many meet it at all. Both rest on the same survey and the same employment count, so moving between them is a decision about what counts as affected. The spread is narrow, about 514,000, because the survey found near-universal exposure, and that near-universality is itself the finding. This is the ordinary working condition of an occupation rather than a burden concentrated in a subgroup.

The band is soft in both directions. It may be too high, because the 11,696 respondents were recruited through trade associations and a routing application, the survey states no sampling frame and no weighting, and the occupation count includes short-haul drivers exempt under 49 CFR 395.1(e)(1) who park at their own yard. It may be too low, because drivers who left the occupation over conditions like this one appear in no employment count. A third source disagrees with both bounds: ATRI reports one space nationally for every 11 truck drivers, which against 313,000 spaces implies about 3,443,000 drivers, roughly 1,200,000 above the federal occupation count, and it defines neither the denominator nor the term it counts.

What this number cannot count at all: other road users struck while a truck stands on a shoulder or a ramp, residents of communities where trucks stage on side streets and vacant lots, bus operators named alongside truck drivers in the FY2026 set-aside, and the public budgets that repair pavement never built for standing heavy loads. It also flattens severity, because a driver who loses 56 minutes and a driver who parks somewhere unsafe count identically here.

Under what conditions does it arise?

1. The rest is compelled and the place to rest is nobody's job. 49 CFR 395 makes the stop mandatory and 49 CFR 395.8 makes it auditable to the minute. FHWA draws the consequence in its own handbook, that drivers nearing the end of allowable drive time may need to stop immediately, and that the alternative to an unsafe stop is operating in violation. No federal instrument attaches a matching duty to supply the space where the stop is taken.

2. Every federal instrument stops one step short of provision. MAP-21 section 1401 declared a national priority and directed a survey, a traffic assessment and a system of metrics; section 1401(b) established eligibility for a list of project types; the IIJA amended 49 U.S.C. 70202 to require every State Freight Plan to assess parking adequacy on a four-year cycle. Survey, label, assessment, eligibility. The 2025 memorandum that consolidates them states that it does not bind the States, and nothing in the set carries a target, a deadline, a performance standard, a penalty or a formula share reserved for parking.

3. The public revenue model is prohibited by statute. 23 U.S.C. 111 bars commercialization of Interstate right-of-way, with vending machines excepted and grandfather clauses for pre-1960 establishments and certain toll roads built without federal funds. A state therefore cannot charge for Interstate rest area parking or lease the lot to an operator so that it pays for itself. H.R. 1659 would extend the same no-fee rule to anything its grants build. Public truck parking is structurally a pure cost center, competing inside the same highway funds as pavement and bridges.

4. The private operator holding 87 percent of supply has no reason to add the marginal space. Truck stops reported running over 100 percent capacity overnight, on weekdays and from May through October, and 79 percent of operators reported no plan to add parking as of 2019. Overnight parking is typically free and the customer buys fuel and food, so a lot that is full at 2 AM is a free good being consumed rather than a signal to build. Land is dearest exactly where the shortage concentrates.

5. Local government holds a third veto and answers to residents. Community pushback is the second-ranked barrier to land acquisition at 27 percent, behind lack of funding at 36 percent and ahead of finding suitable land at 25 percent. A truck parked overnight is a cost to the neighborhood and a benefit to a stranger passing through, which is the distribution local politics resolves against the stranger.

What has been tried?

Seventeen years of reports, one named federal law, a standing coalition, two national surveys, a handbook twice issued and four rounds of grant money have moved public supply by 6 percent across the one five-year interval anyone measured.

What was found?

Why is it still unsolved?

Institutional gap — the rest is compelled by federal rule and the place to rest is assigned to nobody.

Start with the half that binds. 49 CFR 395 does not suggest a rest, it requires one, and since the electronic logging device mandate it requires that rest to the minute and to the location. A limit a driver could once absorb by twenty minutes became a hard stop. Set against that, every federal instrument aimed at parking halts one step short of provision. Jason's Law directed a survey and a system of metrics. MAP-21 attached a national priority label. The IIJA added a state assessment duty on a four-year cycle. Various programs made parking projects eligible for money a state may or may not apply for. The 2025 memorandum that gathers all of it into one document tells the reader in its own text that it does not bind the States. No target, no deadline, no performance standard, no penalty, no reserved share.

Then look at who actually holds the supply, because in this problem the two holders each have a reason not to add capacity and a third party holds a veto over both. States hold about 13 percent of the spaces, 84 percent of them have no dedicated funding line, and 23 U.S.C. 111 forbids the one revenue model that would let a rest area pay for itself. That makes public truck parking a pure cost center, arguing for money against pavement and bridges. Private operators hold the other 87 percent and 79 percent of them reported no plan to add spaces, not despite running over capacity overnight but because of what running over capacity on a free good actually signals. Local government supplies the veto: community pushback is the second-ranked barrier to acquiring land, and a truck parked overnight is a cost to the neighborhood and a benefit to a stranger passing through.

Now put the money against the gap. At the April 2025 median of USD 93,500 per public space, the USD 151 million a year that H.R. 1659 would authorize buys roughly 1,600 spaces, which is about 4 percent of the 40,000 public spaces that exist and about half of one percent of the 313,000 national total, per year, if it were enacted. The USD 61.7 million announced on 2026-07-08 named 99 spaces. And the deficit those sums are measured against has never been stated: fourteen years after Congress declared this a national priority, no published document says how many spaces the country needs. That absence is what separates a gap from a shortage. Support is free and provision is not assigned, and that is the entire mechanism. The cost of the arrangement lands on drivers, who rank parking second among their concerns while the carriers that buy the trucks rank it ninth, and who pay it out of their own revenue miles at 56 minutes a day.

What observation would mean it is solved?

Candidates — (a) a national count showing spaces grown to meet a published national need figure (b) the share of drivers reporting problems finding safe parking falls materially in a repeated federal survey (c) some named entity is placed under a binding duty to supply parking, carrying a target and a schedule.

(a) alone cannot even be stated today. There is no published national need figure to grow toward. Until one exists, a rising count of spaces answers nothing, because 313,000 could be 60 percent of what is required or 95 percent of it and no source opened here separates those cases. A count without a denominator is the condition this problem is already in.

(b) alone rests on a survey that has run twice in eleven years. The 2019 incidence came from a convenience sample recruited through trade associations and a routing application, with no stated frame and no weighting. A later survey drawing a different pool would move the number without anything changing on the road, and the statute that orders the survey says only that it shall be updated periodically, setting no interval and attaching no consequence.

(c) alone counts paper. A duty with no money behind it reproduces the present arrangement one level down, and a duty with money behind it still has to pass the local siting veto that states rank second among their barriers. The three would have to be read together, and none of them can be read at all while the national count stands seven years old.

What is it connected to?

Fills with researchdriver detention time at shipper and receiver facilities, which consumes the same clock as the search for parking · hours-of-service policy itself · the freight contracting that sets delivery windows · commercial vehicle parking provision in other countries · bus and motorcoach parking, named alongside trucks in the FY2026 federal set-aside. Relation type and evidence grade were not confirmed in this round.

What these sources do not say

• How many spaces the country needs. No opened source publishes a national target or a national estimate of required capacity. The federal handbook updated in March 2026 teaches site-level demand estimation and contains no national figure, and the statute asked for a survey and a system of metrics rather than a needs number. Every dollar figure in this dossier is therefore a numerator with no denominator.
• When the national count will be refreshed. As of 2026-08-08 the FHWA truck parking page lists only the 2015 and 2019 surveys, and the 2019 entry carries a line saying no further material is expected to be published. Trade press reported in 2024 that a third survey would launch later that year; no results and no date were found. The statute says the survey shall be updated periodically, which sets no interval and attaches no consequence to not updating.
• The denominator behind one space for every 11 truck drivers. ATRI publishes the ratio with no citation and no definition of the term it counts. Multiplied against 313,000 spaces it implies about 3,443,000 drivers, roughly 1,200,000 more than the federal occupation count for heavy and tractor-trailer drivers as of 2024. Whether the denominator includes local delivery drivers, registered combination trucks or something else decides whether the ratio describes people who need overnight parking or people who go home at night.
• What the 98 percent actually measured, once it leaves the primary. The federal deck splits it 75 percent weekly, 20 percent monthly and 3 percent rarely against 2 percent who reported never. Not one secondary source opened here reproduces that split, and a February 2026 advocacy release converts the whole 98 percent into problems experienced regularly, a word the primary assigns to the 75 percent band. The primary also states no sampling frame and no weighting for the 11,696 respondents.
• What the private 87 percent of supply is doing, what a space costs, and what a dollar buys. The only measurement of private intent found is the 2019 finding that 79 percent of operators had no plan to add parking, and no trade body publishes a running count of private spaces opened or closed, so seven-eighths of national capacity is invisible between federal surveys. On the public side, the median of USD 93,500 published in April 2025 sits against roughly USD 293,000 and USD 409,000 implied by the awards announced on 2026-07-08, with no opened source separating land, construction, technology and maintenance inside an award figure. Nor does any opened source report spaces actually delivered per dollar awarded, or the lag between an award and an opening. USD 752 million and USD 61.7 million are announced as inputs and never closed as outputs.
• Whether the state assessments were done, or add up to anything. Every State Freight Plan has been required since November 2021 to assess parking adequacy and analyze the underlying causes of any shortage, on a four-year cycle. More than fifty such analyses should exist. No opened source aggregates them, compares them or checks whether they were carried out.
• The harm the program exists to prevent. There is no published count of crashes, injuries or deaths involving trucks parked on shoulders or ramps because parking was unavailable. The federal handbook asserts the safety rationale and cites general large-truck fatality totals for 2018 and a fatigue share from a 2007 study, which is a different measurement. Alongside that, the fate of the one dedicated funding bill sits behind retrieval barriers, since the three legislative trackers all refused automated access.

See the evidence

Four federal documents were read directly, and one of them carries the central finding. The FHWA results presentation of 2020-12-01 supplies every 2019 figure in this dossier and is a presentation of survey results rather than the narrative report, which is how it is described above. The FHWA and FMCSA memorandum of 2025-06-27 is the document that establishes the shape of the problem, because it enumerates the federal instruments aimed at truck parking and none of them is an obligation to supply a space. The Truck Parking Development Handbook, updated March 2026, supplies the hours-of-service and right-of-way law, and by still citing 2019 as the latest national data it supplies the staleness finding as well. The text of H.R. 1659 was read in full. The two ATRI reports are primary for their own surveys and secondary for everything else, and everything after that is trade press or advocacy material. Three federal primaries could not be reached at all — bls.gov, transportation.gov and the three legislative trackers all returned HTTP 403 — so the employment base, the FY2026 grant round and the fate of the one dedicated funding bill rest on sources one step removed, and the rows above say so rather than hiding it. Where sources disagree the disagreement is left visible rather than resolved: annual lost wages per driver is USD 4,600 in the March 2026 federal handbook and USD 6,813 in a February 2026 advocacy release, both citing the same 56-minute observation and only one carrying an as-of; the cost of a public space is a median of USD 93,500 in the April 2025 state survey against roughly USD 293,000 and USD 409,000 implied by the July 2026 awards, which also buy technology that is not broken out; the 98 percent figure is reported by the federal primary as problems at any frequency and by the advocacy release as problems experienced regularly, which the primary puts at 75 percent; and two accounts of the same July 2026 award round name different states and different sums, of which the advocacy version is used here on the grounds that its figures are irregular and it names a program, with the other logged and discarded. This is a Path A output (research-based definition), so observation_refs is empty and provenance_mode: press-derived.

Sensitivity The interval is not a confidence interval and its width does not express measurement uncertainty. Both bounds use the same survey and the same employment count, and the distance between them is a definitional choice: the lower bound counts drivers who meet the problem at least weekly, the upper bound counts drivers who meet it at all. The spread is narrow, about 514,000, because the underlying survey found near-universal exposure, and that near-universality is itself the finding. This is the ordinary working condition of an occupation rather than a burden concentrated in a subgroup. The band is soft in both directions and neither correction could be computed from the sources opened in this round. It may be too high, because the 11,696 respondents were recruited through trade associations and a routing application, the survey states no sampling frame and no weighting, and the occupation count includes short-haul drivers exempt under 49 CFR 395.1(e)(1). It may be too low, because drivers who left the occupation over conditions like this one appear in no employment count. A third source disagrees with both bounds: ATRI reports one truck parking space nationally for every 11 truck drivers, which against the 313,000 spaces counted in 2019 implies about 3,443,000 drivers, roughly 1,200,000 above the federal occupation count, and it defines neither the denominator nor the term it counts. What this number cannot count at all is other road users struck while a truck stands on a shoulder or a ramp, residents of communities where trucks stage on side streets and vacant lots, bus operators named alongside truck drivers in the FY2026 federal set-aside, and the public budgets that repair pavement never built for standing heavy loads. It also flattens severity, because a driver who loses 56 minutes of drive time and a driver who parks somewhere unsafe count identically here.

Regional breakdown No source opened in this round gives a state-level count of exposed drivers, and none gives parking spaces by state. The 2019 federal survey maps shortage corridors rather than publishing state totals, and the April 2025 state survey reports shares of states rather than counts of drivers. Splitting the national band by state population would be proportional allocation and would be wrong in an unknown direction, because exposure follows long-haul freight corridors and the shortage concentrates on named routes such as I-95, the Pacific corridors and the states surrounding Chicago rather than distributing with where drivers live.
