Driver protection device Rear end collision prevention Truck Mounted Attenuator

The truck mounted attenuator is installed in the rear of the truck. The red and white reflective film has an obvious warning function to the driver. If a rear end accident occurs, it can reduce the impact force produced by the vehicle collision, and prevent the front body of the car from entering the rear of the truck during the collision, which greatly protects the safety of the driver and the vehicle.

When the accident occurs, if the truck mounted attenuator is not installed, the front part of the car will be stuck at the rear of the truck due to impact. The accident will be very serious and may cause serious injury to the driver of the rear vehicle.

If a crash beam is installed, the extended part of the beam can not only cushion the impact force, but also prevent the car from hitting the bottom of the truck.
