Did you use the Emergency Response service? Let us know how we did!

MoDOT’s Emergency Response operators work hand in hand with local law enforcement, fire departments and private towing agencies to keep traffic moving. Emergency Response operators can help change tires, provide fuel and perform other minor, short term repairs. MoDOT’s Emergency Response crews assist fire department, police and EMT crews during major crashes. They also respond to emergency roadway cleanups, debris clearing, pothole patching and hundreds of other functions to improve the safety of the roadway during off hours.

Motorists who become stranded on patrol routes should pull off onto the right shoulder as far as possible and, if safe, wait with their vehicle until a Emergency Response truck arrives. Missouri state law requires vehicles to pull out of the driving lane after an accident unless there are injuries or the vehicles are not capable of being moved.
