Height mismatches
Damage from a low-speed but high-level impact; the energy-absorbing front off road pickup truck bumper system is completely bypassed and untouched.
For passenger cars, the height and placement of pickup truck bumper s is legally specified under both US and EU regulations. pickup truck bumper s do not protect against moderate speed collisions, because during emergency braking, suspension changes the pitch of each vehicle, so pickup truck bumper s can bypass each other when the vehicles collide. Preventing override and underride can be accomplished by extremely tall off road pickup truck bumper surfaces. Active suspension is another solution to keeping the vehicle level.
pickup truck bumper height from the roadway surface is important in engaging other protective systems. Airbag deployment sensors typically do not trigger until contact with an obstruction, and it is important that front off road pickup truck bumper s be the first parts of a vehicle to make contact in the event of a frontal collision, to leave sufficient time to inflate the protective cushions.
Energy-absorbing crush zones are completely ineffective if they are physically bypassed; an extreme example of this occurs when the elevated platform of a tractor-trailer completely misses the front pickup truck bumper of a passenger car, and first contact is with the glass windshield of the passenger compartment.
Truck vs. car
Underride collisions, in which a smaller vehicle such as a passenger sedan slides under a larger vehicle such as a tractor-trailer often result in severe injuries or fatalities. The platform bed of a typical tractor-trailer is at the head height of seated adults in a typical passenger car, and can cause severe head trauma in even a moderate-speed collision. Around 500 people are killed this way in the United States annually.
Following the 1967 death of actress Jayne Mansfield in an auto/truck accident, the US government agency NHTSA recommended requiring a rear underride guard, also known as a "Mansfield bar", an "ICC bar", or a "DOT (Department of Transportation) pickup truck bumper ". They are required to be not more than 22 in (56 cm) from the road.[18] The trucking industry has been slow to upgrade this safety feature,]and there are no requirements to repair ICC bars damaged in service. However, in 1996 NHTSA upgraded the requirements for the rear underride prevention structure on truck trailers, and Transport Canada went further with an even more stringent requirement for energy-absorbing rear underride guards, and in July 2015 NHTSA issued a proposal to upgrade the US performance requirements for underride guards.
