US 218 carries freight north out of the Cedar Valley toward Minnesota and south toward the Cedar Rapids and Iowa City corridor. Much of it runs as four lane divided highway, which means a stopped truck has a shoulder and not much else.

South of Waterloo it runs alongside I 380 and serves La Porte City at US 20 Exit 232A.
Through Waterloo and Cedar Falls it merges with Iowa 27 and the US 20 interchanges.
North through Janesville and Waverly it is the main route for freight heading toward Minnesota.
It carries a heavy mix of farm and commercial traffic through grain season.
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.
