Things happen fast on the road. The flow of traffic can change with a second’s notice. Since you’re driving a tow truck, you need as much notice as possible to be able to adjust to sudden changes on the road, like someone having to hit the brakes hard. To give yourself time to react and slow your tow truck or wrecker, you need to have lots of following distance between your tow truck and the car in front of you. Personal space is a good thing.
Even if you drive carefully and defensively, if you’re tailgating you might not have a way to prevent hitting the car in front of you if they have to slow down suddenly. Leaving plenty of following distance in front of the tow truck is a simple way to stop a rear-end accident from happening. And preventing accidents means saving money on your tow truck insurance rates!
