How flatbed and other common towing methods differ, and what can affect the choice.
A flatbed carries the vehicle on the truck deck. It can be useful for AWD vehicles, specialty vehicles, damaged vehicles and situations where keeping all wheels off the road is preferred.
Wheel-lift towing raises one end of a vehicle while the other wheels remain on the road. Whether it is suitable depends on the vehicle, drivetrain, condition and manufacturer guidance.
Drivetrain, ground clearance, wheel damage, steering condition and recovery location all matter. Tell the dispatcher exactly what you are driving and what condition it is in.
