Head-on collision with two cars involved Standard wrong-way sign package used on all freeway off-ramps in the state of California to prevent head-on collisions [1]. A head-on collision is a traffic collision where the front ends of two vehicles such as cars, trains, ships or planes hit each other when travelling in opposite directions, as opposed to a side collision or rear-end collision.
Head-on collisions often have poor outcomes because of the speed involved when the collision takes place. In a head-on collision, the vehicle speeds are additive—the effective collision speed is the sum of the speeds of the two vehicles.
A "perfectly inelastic" collision (also called a "perfectly plastic" collision) is a limiting case of inelastic collision in which the two bodies coalesce after impact. An example of such a collision is a car crash, as cars crumple inward when crashing, rather than bouncing off of each other.
This helps any driver that runs off the edge of the roadway to maintain control while trying to steer back onto the pavement. A vertical edge drop-off often results in overcorrection, leading to a head-on collision, rollover, or a run-off-road collision on the far side of the road. Pavement edge drop-offs are problematic on roads where the hard ...
The head-on crash happened April 10 on state Route 542 near Dellroy in Carroll County. The collision killed Randy L. Simmons, 60, of East Liverpool, and two of his passengers, ...
A crash test illustrates how a crumple zone absorbs energy from an impact. Road Maintenance Truck Impact Attenuator, Auckland, New Zealand Extent of the crumple zones (blue) and the driver's safety cell (red) of an E217 series train The crumple zone on the front of these cars absorbed the impact of an offset head-on collision.
Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. . Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver(s), vehicle(s), roadway and gen
A traffic collision in Japan, 2007 The aftermath of an accident involving a jackknifing truck, Mozambique, Africa. 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.
