US 20 is the east and west freight route across northern Iowa. Through Black Hawk County it is a full expressway, and the interchanges from Exit 208 to Exit 238 are the heart of the service area.

Exit 227 at US 63 is the Love’s travel stop and one of the most common call locations.
Exits 224 and 225 serve Cedar Falls and the Iowa 58 industrial corridor.
Exits 232A and 232B are the I 380 and US 218 junction, the busiest interchange on the route.
West of Exit 208 the services thin out fast and a breakdown means a long wait for anyone but a mobile truck.

Have This Ready When You Call
Three answers cut the response time more than anything else you can do.
- Your exact locationHighway, direction of travel, the last mile marker or exit you passed, the scale, the truck stop or the jobsite address. If you have a phone location, read the coordinates. Being one exit off can cost an hour.
- The unitYear, make and model of the tractor or trailer, the unit number, and the tire size if it is a tire call. For a reefer, the make and model of the unit itself. This is what decides which parts come on the truck.
- What actually happenedWarning lights and fault codes word for word, noises, smells, leaks, and what the unit will and will not do. What it was doing in the minute before it stopped matters more than almost anything else.
