While road workers were performing maintenance on a roadway section, a driver traveling down a 4% grade crashes into the road maintenance equipment. The posted speed limit is 60 mph, and the driver is being sued. There were two warning signs: the first is located 1000 ft before the maintenance equipment, and the second located at 600 ft. The accident investigation team determined the following: the vehicle was traveling 30 mph when it struck the maintenance equipment, braking skid marks started 205 ft before the struck object, coefficient of road adhesion is estimated to equal 0.6, and the braking efficiency of the vehicle was 93%.
