From March through November, the Iowa DOT may have up to 500 road construction work zones, and each of the department's maintenance garages may establish one or more short-term work zones per day. Couple that with the work of cities and counties, and motorists can expect to see thousands of work zones during this period.
These work zones require extra caution on the part of drivers, so they need to pay close attention to the movements of traffic around them, as well as the location of road workers whose jobs often put them extremely close to traffic.
Links on these pages provide tips on safe driving in road work zones, and statistics concerning crashes taking place in work zones.
