Truck parking on I-15

I-15 truck parking in numbers

I-15 has 37 public truck parking sites in the federal inventory, with 547 truck spaces across 4 states. That is an average of 15 spaces per site, against a national median of 15 for all public sites.

The most spaces are in Utah (240, 44 percent of the route), then Montana (171). The fewest are in Nevada, with 56 at 6 sites.

The largest site is St. George (NB) in Utah, at mile 1, with 54 truck spaces.

The longest stretch between two listed public sites in the same direction is in Utah: about 239 miles along the route, between mile 87 and mile 326. Private truck stops may fill part of that gap; plan the last stop of the day before you reach it.

These are capacities from the Bureau of Transportation Statistics inventory, not live availability, and private truck stops are not included. The hours of service guide explains why the 14-hour window, not the 11 hours of driving, decides where you need a space, and truck parking by state compares I-15 with the other interstates.
