How far apart are rest areas on U.S. interstates? The most common range is 30 to 60 miles. In our directory, the median distance from one public rest stop to the next in the same direction is 44 miles, measured by official mile markers across 644 gaps. That is roughly 40 minutes of driving at 65 mph. The spread is wide, though: in Connecticut the median gap is 13 miles, in Texas it is 86.
No federal rule fixes the distance. Federal guidance has treated about one hour of driving as a reasonable maximum, and each state decides where its rest areas go and whether to keep them open. Below is how we measured the gaps, what the numbers look like state by state, where the guidance comes from, and how to plan around long stretches.
How far apart are rest areas in our data?
The answer depends on the state, but the overall pattern is clear. Of the 644 gaps we could measure:
| Distance to the next stop (same direction) | Share of gaps | Approx. driving time at 65 mph |
|---|---|---|
| Under 30 miles | 21% | under 28 min |
| 30 to 60 miles | 47% | 28 to 55 min |
| 60 to 90 miles | 19% | 55 min to 1 h 23 min |
| 90 miles or more | 13% | 1 h 23 min or more |
The median gap is 44.0 miles and the mean is 54.0 miles. The mean is higher because a minority of very long gaps pulls the average up. That is why the median is the better “typical” figure. Put plainly: about two in three gaps are under an hour of driving, and roughly one in three is longer.
The driving-time column is our own arithmetic (distance ÷ 65 mph). Your real time depends on the speed limit, traffic, weather and grades.
How we measured the distance between rest areas
Our numbers come from the live RestStopsNearMe directory as pulled on November 1, 2026. A gap counts only when all of these are true:
- Two consecutive public stops: rest areas, welcome centers and service plazas listed in our directory. Private truck stops, weigh stations and scenic viewpoints are not part of the directory, so they are not in the measurement.
- Same interstate, same state, same direction. A northbound stop is only compared with the next northbound stop. Many rest areas serve one direction only, so this matches what you can actually pull into.
- Official mile markers. The distance is the difference between the two stops’ mileposts, not a straight line on a map.
- Route-absolute mileposts only. For some states, the mileposts available to us can’t be compared along the whole route. Those states are left out of the spacing statistics rather than estimated.
Gaps that cross a state line are not measured, because each state numbers its own mile markers. So a stretch where the last stop in one state and the first in the next are far apart can be longer than anything shown here.
The biggest caveat is completeness. A gap in our data can look longer than it really is when a rest area is missing from our directory. It can also look shorter on the road if a stop is closed. That is why we don’t publish a list of “longest gaps” as fact. One example: our data shows a 212-mile gap on I-40 in Arizona between the Haviland (milepost 23) and Meteor Crater (milepost 235) rest areas. The Arizona DOT, however, lists a Parks Rest Area at milepost 182 on I-40 west of Flagstaff, which it reopened in 2020 with parking for commercial vehicles only (ADOT). It is not in our directory, so for truck drivers, at least, the real gap is shorter. If you rely on a long stretch being stop-free (or not), check the state DOT’s rest area list or its 511 traveler information before you go. Our data sources page explains where each listing comes from, and you can report a missing stop.

| Texas | 86 mi | 41 |
Three things stand out. First, the densest spacing is in the Northeast: Connecticut and New Jersey both have closely spaced service areas on I-95. Second, a median describes the typical gap, not the worst one; a state with a short median can still have individual stretches well over an hour long. Third, states with fewer than ten measured gaps (Oregon, South Dakota, Wisconsin, West Virginia) have medians that can shift noticeably when a single stop is added or closed. Treat those as rough indications.
States missing from the table either had fewer than six measurable gaps or use mileposts we couldn’t compare along the route.
Is there a federal rule for rest area spacing?
There is no federal regulation that sets a minimum or maximum distance between rest areas. A 1998 report by the Virginia Department of Transportation to the state’s General Assembly put it directly: “no regulations exist about minimum distances between rest areas” (Virginia House Document No. 16, 1998).
What does exist is guidance, and it has changed over time:
- About half an hour (1960s). The same Virginia report summarizes a 1968 study by the national association of state highway officials (today’s AASHTO), which recommended a rest area for short stops about every half hour of driving. The report equates that to roughly 30 to 35 miles at 65 mph. Iowa DOT describes the same early “half-hour guidance” in its rest area management report.
- About one hour (1980s onward). The Virginia report cites a 1981 U.S. DOT study suggesting one-hour spacing. FHWA’s 1992 guidance on the federal rest area rules (23 CFR 752) states that “a spacing of an hour’s driving time or less is considered to be reasonable” unless there are extenuating circumstances, and attributes that to FHWA’s publication Safety Rest Area Planning, Location, and Design (FHWA-IP-81-1) (archived FHWA guidance, 1992).
The context of that FHWA sentence matters. It appears in the section on when a state may close an interstate rest area: the state has to document that the remaining rest areas are adequate and “reasonable” distances apart. In other words, one hour is a test for closures, not a construction quota. Iowa DOT still uses “approximately one hour’s drive time or less” as a criterion when it evaluates rest areas.
The federal regulation itself, 23 CFR 752.5, covers what a safety rest area should provide and how sites are chosen (scenic quality, access and utilities), but it sets no spacing distance.
Some states have studied shorter spacing for safety reasons. A study done for MnDOT (2007, summarized in 2009) found that single-vehicle truck crashes, used as a stand-in for drowsy-driving crashes, increased beyond 30 miles from a rest area. Its conclusion: spacing Minnesota interstate rest areas “at 30 miles or less will reduce drowsy driving-related crashes” (MnDOT rest area spacing study summary).
Measured against the one-hour benchmark, our data fits the guidance most of the time. About 68% of measured gaps are under 60 miles. The 13% of gaps at 90 miles or more are the stretches worth planning for.
Where the long stretches between rest areas are
Long gaps cluster where traffic is light and distances are large: the interstates of the West, the Great Plains and parts of the South. The state medians above point the same way. Texas (86 miles), Wisconsin (84), Colorado (78), Alabama (68), South Dakota (67) and Oregon (65) all have typical gaps above an hour of driving at 65 mph.
Corridors where our data shows gaps of more than 100 miles between public stops include I-15 in Utah, I-20 and I-35 in Texas, I-40 in Oklahoma and North Carolina, I-70 in Kansas and Colorado, I-75 in Georgia and Florida, and I-90 in Montana. Some of those stretches are real; others may shrink once a missing stop is added. Exact distances should come from the state DOT’s current list.
Two things make a long gap more serious than the number suggests. Rest areas close, sometimes for months, for construction or budget reasons (see rest area closures). And interstate rest areas usually don’t sell fuel: federal law bars service stations and other commercial establishments on interstate rights-of-way, with narrow exceptions (23 U.S.C. 111). On a long rural stretch, fuel and restroom stops may be at different places. Our guide to rest areas vs. truck stops explains the difference.
How to plan stops around rest area spacing
A few habits make the spacing numbers useful on an actual trip:
- Check your route before you leave. Open the interstate page, for example I-80, and note where stops sit along your direction of travel. Stops on the other side of the highway usually aren’t reachable without exiting and turning around.
- Look up the next stop while you’re on the road. The rest stop finder shows the nearest public rest areas from your location. Let a passenger do this, or do it before you set off again.
- Stop at the last rest area before a long stretch. If the next public stop is 90 miles or more away, take the break now rather than hoping for an exit with services.
- Plan fuel separately. Rest areas on interstates generally don’t sell fuel. Service plazas on toll roads are the exception; the 14 plazas on the Ohio Turnpike, for example, sell fuel and food and are open 24 hours (Ohio Turnpike).
- Check closures and hours. Confirm the stop is open on the state DOT or 511 site; a closed rest area can double a gap.
- Don’t push through drowsiness. NHTSA advises pulling over for a short nap in a safe place, “such as a lighted, designated rest stop” (NHTSA, drowsy driving). Our guide are rest areas safe? covers how to stop safely.
Truck drivers have an extra constraint. Federal hours-of-service rules require property-carrying drivers to take a 30-minute break once they have driven 8 hours, and they limit driving to 11 hours after 10 consecutive hours off duty (49 CFR 395.3). Truck parking at a given rest area can be full when you arrive, so plan a backup stop. See truck parking at rest areas and the truck rest stop directory, including time limits by state.
RV drivers and anyone traveling with pets should know that amenities differ from stop to stop. Our listings show documented amenities; “unknown” means no source confirmed it, not that it’s missing. See RV dump stations and rest areas with pets.
Common questions about rest area spacing
Do welcome centers count as rest areas in these numbers?
Yes. We count rest areas, welcome centers and service plazas listed in our directory, because all three are public stops you can reach from the highway. Service plazas on toll roads work differently from DOT rest areas; see toll road service plazas and welcome centers.
Why does our spacing differ from other sites’ numbers?
Methods differ. We only measure gaps along official mileposts within one state, in one direction, and we leave out states where mileposts can’t be compared. Mixing straight-line distances or cross-border gaps gives different results. Directory completeness matters too: every missing stop makes a gap look longer.
