Every driver knows truck parking is short. Fewer people know where it is short. This page counts it, state by state and interstate by interstate, from the two datasets this directory is built on: the federal inventory of public truck parking kept by the Bureau of Transportation Statistics, and the truck stops mapped in OpenStreetMap. The figures are ours, computed in September 2026, and the limits of each dataset are set out at the end.
The national picture
- The federal inventory lists 1,915 public truck parking sites in 48 states with 39,803 truck spaces between them. Alaska, Hawaii and the District of Columbia have none in it.
- The typical (median) public site has 15 truck spaces. A handful are far larger: the Greenfield rest area on I-70 eastbound in Indiana has 201, the Vince Lombardi service area in New Jersey 164.
- OpenStreetMap maps 3,245 private truck stops, truck diesel lanes and service plazas: 2,348 truck stops, 622 service plazas and 275 fuel stations mapped as serving heavy trucks.
Public rest areas and private truck stops are different things for a driver. A rest area is free and usually has a posted time limit; a truck stop has fuel, food and showers and increasingly sells reserved spaces. Both appear below, separately.
Public truck spaces: the ten largest states
| State | Public truck spaces | Sites |
|---|---|---|
| Florida | 2,982 | 87 |
| Ohio | 2,588 | 95 |
| Indiana | 2,531 | 41 |
| New York | 1,791 | 78 |
| Georgia | 1,701 | 45 |
| Illinois | 1,670 | 81 |
| Pennsylvania | 1,670 | 71 |
| Michigan | 1,657 | 76 |
| California | 1,251 | 83 |
| Texas | 1,237 | 66 |
Indiana stands out: 41 sites, fewer than half of Ohio's, but almost as many spaces, because its rest areas on I-65, I-70 and I-80/90 are large. Texas is the opposite case. It has the most truck stops of any state by a wide margin but only the tenth-largest public parking inventory, so drivers there lean on private lots far more than in the Midwest.
At the other end, Delaware (93 spaces at 2 sites), Rhode Island (97 at 7), North Dakota (189), New Hampshire (194) and Colorado (332 at 24 sites) have the least public truck parking in the inventory.
Interstates with the most public spaces
| Interstate | Public truck spaces | Sites |
|---|---|---|
| I-80 | 3,507 | 139 |
| I-95 | 3,386 | 99 |
| I-90 | 2,817 | 144 |
| I-75 | 2,732 | 87 |
| I-70 | 2,188 | 88 |
| I-10 | 1,708 | 78 |
| I-40 | 1,280 | 76 |
| I-65 | 1,122 | 33 |
| I-5 | 1,064 | 53 |
| I-35 and I-94 | 1,057 each | 53 and 52 |
Of the 39,803 public spaces, 35,446 (89 percent) are on the Interstate system. Counts are for both directions together; a rest area is usually on one side of the road only, which matters more than the total when planning the last stop of a day. Each route has a page in the directory that lists the sites in mile-marker order, for example the truck parking section and its interstate pages.
Truck stops: where the chains are
By OpenStreetMap's count, Texas has 450 truck stops, diesel lanes and service plazas, more than twice the next state, Illinois (187). Then Ohio (152), Georgia (144), Indiana (125), Missouri (117), Oklahoma (111), California (109) and Florida (106).
Brands are recorded for most of them. The largest by number of mapped locations are Love's (822), Pilot (607), Flying J (286), TA (273), QuikTrip (127) and Petro (99), followed by Road Ranger, ONE9, Buc-ee's and Sapp Bros. Pilot and Flying J are one company, and TA and Petro are one company, so the two largest networks are each around 900 locations in this data.
Three states stand out for how few truck stops they have relative to their public parking: New York (56 truck stops against 1,791 public spaces), Michigan (36 against 1,657) and Florida (106 against 2,982). In those states the public rest area is the main option, not the backup.
How to use these numbers
- Plan against the 14-hour window, not the 11 hours. The window keeps running while you look for a space; see the hours of service guide.
- Know the median. A typical public site has 15 spaces. After early evening on a busy corridor, assume a small rest area is full and have the next one in mind.
- On low-inventory corridors, use the split. A 7/3 or 8/2 sleeper split lets you take the long rest later at night, when some lots have turned over.
- Mix the two lists. In Texas and Oklahoma, truck stops are dense and public parking thin; in New York, Michigan and Florida the reverse.
What these datasets do not tell you
- No live availability. The federal figure is capacity, not how many spaces are free.
- The federal inventory is public parking only. It is mostly rest areas and welcome centers. Private truck stop lots are not in it, which is why truck stop counts come from a second source.
- OpenStreetMap is volunteer-mapped. Coverage is good for the national chains and uneven for small independents, and a few states (Delaware, Vermont, the District of Columbia) have almost nothing mapped. Treat the truck stop counts as a floor.
- Closures. Rest areas close for works. Check the state transportation department before relying on a site.
