Side collisions are vehicle crashes where the side of one or more vehicles is impacted. These crashes often occur at intersections, in parking lots, and when two vehicles pass on a multi-lane roadway.

Maps, Directions, and Place Reviews



Broadside or T-bone collision

Broadside collisions are where the side of one vehicle is impacted by the front or rear of another vehicle, forming a "T". In the United States and Canada this collision type is also known as right-angle collision or T-bone collision; it is also sometimes referred to by the abbreviation "AABS" for "auto accident, broadside". Vehicle damage and occupant injury are more likely to be severe, but severity varies based on the part of the vehicle that is struck, safety features present, the speeds of both vehicles, and vehicle weight and construction.

When a vehicle is hit on the side by another vehicle, the crumple zones of the striking vehicle will absorb some of the kinetic energy of the collision. The crumple zones of the struck vehicle may also absorb some of the collision's energy, particularly if the vehicle is not struck on its passenger compartment. Both vehicles are frequently turned from their original directions of travel. If the collision is severe, the struck vehicle may be spun or rolled over, potentially causing it to strike other vehicles, objects, or pedestrians. After the collision, the involved vehicles may be stuck together by the folding of their parts around each other.

An occupant on the struck side of a vehicle may sustain far more severe injuries than an otherwise similar front or rear collision crash.

Side-impact airbags can protect vehicle occupants during side collisions, but they face the same limitations as other airbags. Additionally, side impact wrecks are more likely to involve multiple individual collisions or sudden speed changes before motion ceases. Since the airbag can only provide protection during the first collision, it may leave occupants unprotected during subsequent collisions in the crash. However, the first collision in a crash typically has the most severe forces, so an effective airbag provides maximum benefit during the most severe portion of a crash.

Broadside collisions are frequently caused by a failure to yield right of way. In the case of collisions in an intersection, the cause is often a result of one vehicle failing to obey traffic signals (fail to stop or running past a red light). As with any crash, increased speed may increase crash severity.

Testing

Euro NCAP, IIHS and NHTSA test side impacts in different ways. As of 2015, they all test vehicle-to-vehicle side impacts, where heavier vehicles have lower fatality rates than lighter vehicles.

NHTSA and EuroNCAP also test the more severe vehicle-into-pole side impacts, where smaller vehicles have the same fatality rate as larger vehicles.

Newer cars have improved safety of front crashes, but side impacts are also deadly; about 9,700 people were killed in side impacts in the US in 2004. Side airbags became mandatory in 2009 in the USA, saving an estimated 1,000 lives per year. Research indicates that the vehicle's underbody is the best place to reinforce structures to reduce intrusion by the pole.

General list of side impacts

These are lists of cars with notable aspects of side impact.

List of cars after 2011

The NHTSA results are evaluated by the National Highway Traffic Safety Administration using Office of Crashworthiness Standards, New Car Assessment Program (NCAP) Side Impact Laboratory Test Procedure and Side Impact Rigid Pole Laboratory Test Procedure to display a simple star-rating. The "primary purpose of the NCAP side impact program is to provide comparative vehicle side protection information to assist consumers in making vehicle purchase decisions, thereby providing an incentive for vehicle manufacturers to design safer vehicles."

The IIHS results are evaluated by Insurance Institute for Highway Safety using their protocols.

This list shows the most notable of newer tested vehicles tested via NHTSA and IIHS. Some provide good protection, some less so, and some developed improved safety in response to a low result (Dodge Ram and Fiat 500). Some are common examples of their type.

Sorted roughly by rating, Head injury criterion (HIC) and Crush.

Limits are:
Moving Deformable Barrier (MDB): HIC max. 1000, Chest injury max. 44mm, abdominal injury max. 2500 Newton, pelvis injury max. 6000 N. There are additional limits for passenger similar to pole test.
Rigid Pole: HIC max. 1000, Lower Spine acceleration max. 82g, Pelvis sum max. 5525 N

List of cars before 2011
