Vehicle-ramming attack in the context of "Traffic collision"

A traffic collision, also known as a motor vehicle collision or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is statistically the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy. The commonly used term car accident is increasingly falling out of favor with many government departments and organizations: the Associated Press style guide recommends caution before using the term and the National Union of Journalists advises against it in their Road Collision Reporting Guidelines. Some collisions are intentional vehicle-ramming attacks, staged crashes, vehicular homicide or vehicular suicide.

Several factors contribute to the risk of collisions, including vehicle design, speed of operation, road design, weather, road environment, driving skills, impairment due to alcohol or drugs, and behavior, notably aggressive driving, distracted driving, speeding and street racing.

A "soft target" is a person, thing, or location that is easily accessible to the general public and relatively unprotected, making it vulnerable to military strikes, terrorism, car bombs, or crimes such as vehicle-ramming attacks or mass shootings. By contrast, a "hard target" is heavily defended or not accessible to the general public.
