If you've recently been stuck in traffic caused by an accident on the motorway, you know that totalled vehicles cause congestion and danger when left sitting on the road for too long. A severe accident may result in a flipped car or auto parts strewn about multiple car lanes.
Hopefully you never get in a bad accident, but if you do, a tow truck can come to the scene to haul your car or truck to safety.
The last thing you want to worry about after an accident is getting your truck off the road, so let a tow truck do it for you. Even if your truck seems safe to drive, don't take your chances. Get it towed and have a mechanic give it a once over before you drive it again.
