01Move out of active traffic if possible
If the vehicle can be moved safely, guide it as far from travel lanes as conditions allow without creating a new hazard. If it is stopped in a live lane or cannot be moved safely, call 911 and follow emergency instructions.
02Make the vehicle visible
Use hazard flashers when appropriate. Do not walk into traffic to place triangles, flares, signs, or other warnings. Visibility tools help only when they can be used without increasing your exposure.
03Choose the safest waiting position
MoDOT advises staying inside a safely positioned disabled vehicle and avoiding exit into traffic. Keep the seat belt fastened. Leave only when fire, smoke, water, unstable terrain, traffic impact, or another immediate hazard makes remaining inside unsafe, and move away from traffic if you can do so safely.
04Do not attempt a roadside repair near traffic
Do not change a tire, inspect damage, retrieve an object, push the vehicle, or work under the hood in or near a live lane. A damaged tire or rim is less important than preventing a roadside strike.
05Share the exact carriageway
Give the highway number, direction of travel, nearest exit or mile marker, which shoulder, the last sign passed, a map pin, vehicle description, and whether ramps, barriers, bridges, construction, or divided lanes affect access.
06Confirm the assigned response
Tell dispatch whether police, highway assistance, insurance, or another tow provider is already involved. Keep your phone available and do not assume a website request, email, or location pin assigned a truck.
