If you've added roadside assistance or emergency road service to your full coverage car insurance, your policy probably includes towing services. But if your full coverage only consists of collision and comprehensive insurance, towing is generally only covered when a covered incident — such as an accident or theft — renders your car undrivable. If the incident isn't covered by your collision or comprehensive insurance, your insurer usually won't cover the towing costs.
Roadside assistance typically includes towing, regardless of the reason for the breakdown. This includes mechanical issues, flat tires, dead batteries and other situations where your car is disabled.
