The structural steel of bridges and overpasses can also be weakened by the heat. The destruction and intense heat of fires can also damage roadways, particularly by melting and burning the asphalt or spalling concrete surfaces. If the collision takes place in a remote area, getting medical help to the scene can be difficult. Multiple-vehicle collisions can also overwhelm local emergency services making speedy rescues more difficult. Collisions after the initial collision may occur from the side of the vehicle, where the passenger compartment is more vulnerable.Ī fire in one part of the collision can quickly spread via spilled gasoline and cover the entire crash area. Individual vehicles in a multiple-vehicle collision are often hit multiple times at high speed, increasing the risk of injury to passengers who may have survived the first impact with the benefit of now-discharged protective airbags. Even if survivors are able to exit their vehicles, other cars may strike them. Multiple-vehicle collisions are particularly deadly as the mass of crumpled vehicles makes escape for survivors difficult. Effects Emergency services work on the scene of a multiple vehicle collision in Toronto. In spite of their frequency, little formal research has been done in the United States regarding their causes. Considering that these roads often have high traffic volumes, more cars are forced into braking and skidding, darting into other lanes and in front of other traffic more vehicles become involved, creating a chain reaction effect.ĭetermining the cause of such collisions is difficult for investigators and it is often impossible to tell if negligence caused the crash. Due to the high traffic speeds on the road, if one car develops a problem and suddenly halts, ones behind it cannot stop in time and may hit it. Multiple vehicle collisions can also occur when a third vehicle is too close to an initial collision to avoid hitting one or both of the vehicles. Pile-ups generally occur in low-visibility conditions as drivers on freeways are following too closely and unable to adjust to road conditions.Ĭhain-reaction crashes can also occur in conditions of good visibility, when black ice or other road hazards are encountered unexpectedly as drivers round a curve or crest a hill. Graphs are unavailable due to technical issues. In crashes with three or more vehicles there was 200 motorists killed (18% of all motorists killed) and 17 pedestrians killed (5% of all pedestrians killed). In 2020, there were: 25730 single vehicle crashes, 57392 dual vehicle crashes, 8077 crashes involving three or more vehicles (9%) for a total of 91199 reported crashes.In crashes with three or more vehicles there were 228 motorists killed and 19 pedestrians killed. In 2013, there were: 42487 single vehicle crashes, 82429 dual vehicle crashes, 13744 crashes involving three or more vehicles (10%) for a total of 138660 reported crashes.In Great Britain, statistics are available on the number of vehicles involved in crashes. The most disastrous pileups have involved more than a hundred vehicles.Ī chain collision can be defined as "an accident involving 3 or more vehicles in which one vehicle has only rear impact damage (i.e., the "lead" vehicle) one vehicle has only frontal damage and all other vehicles have frontal and rear impact damage (these are the "middle" vehicles)". Generally occurring on high-capacity and high-speed routes such as freeways, they are one of the deadliest forms of traffic collisions.
