A rear collision (often called only back-end or in the UK shunt ) is a traffic accident in which the vehicle (usually a car or truck) vehicle in front of it. Common factors that contribute to rear collisions include by driver's lack of attention or disruption, tailgating, panic stops, and reduced traction due to weather or sidewalk use. It may also be a train wreck where the train goes to the back of the previous train.

Overview
The typical scenario for the rear end is a sudden slowdown by the first car (for example, to avoid someone crossing the road) so the car in the back does not have time to brake and collide with the first. Or the following car may accelerate faster than the lead (eg, leaving the intersection) resulting in a collision.
As a rule of thumb, if both vehicles have the same physical structure, bumping into another car is equivalent to crashing into a rigid surface (like a wall) at half of the closing speed. This means that the rear end of the stationary car while traveling at 50 km/h (30 mph) is equivalent, in the case of deceleration, to crash into the wall at 25 km/h (15 mph). The same is true for vehicle crashing. However, if one vehicle is significantly more rigid (eg the rear of the truck) then the deceleration is usually more reflected by the full closing speed for the less rigid vehicle.
The typical medical consequence of the back end, even in the case of a moderate-speed collision, is whiplash. In more severe cases, permanent injury, eg. herniation, may occur. The rearmost passengers in minivans benefit only from the shorter rear crumple zones, making them more likely to be injured or killed in rear-end collisions.
For insurance and police purposes, the driver of the car who crashed into the back of another car is almost always considered wrong because it does not leave enough stopping distances or lack of attention. Exceptions to this rule will apply if the vehicle on the back has a reverse gear. If the driver of the car located on the back end of the file claims against the driver who hit him, said the driver could be responsible for all damage to other car drivers. According to data reported by NHTSA, the percentage of accidents behind to all collisions is between 23-30%.
Ford Pinto became the focus of widespread concern when it was alleged that defects in its design could cause a fire from refueling as a result of rear collisions.
The latest developments in automated security systems have reduced the number of rear collisions, as they serve as a second-checking system if drivers fail to avoid vehicles ahead.
