Side underride guards, also known as lateral protective devices (LPDs), are designed to prevent pedestrians, cyclists, and motorcyclists from being swept under a large vehicle’s rear wheels in a side-impact collision. They are typically mounted on the sides of trucks between the axles. Angelwing
Purpose:
– Prevent Underride:
The primary function is to prevent vulnerable road users from being caught under the wheels of a large truck in a side impact crash
– Reduce Injuries and Death:
By prevening underride, these guards can help reduce the severity of injuries and fatalities in side-impact collisions.
– How they work:
Side underride guards act a physical barrier, preventing pedestrians, cyclists, and motorists from being swept under the wheels. They are designed to deflect these vulerable users away from the truck’s rear wheels.
With over 14 years of experience of real-use mileage under our wheels, our side guard systems have withstood everything the road can throw at them.
