A head-on collision occurs when the front ends of two vehicles collide directly with each other. This type of accident often results in severe damage to both vehicles and can lead to serious injuries for the occupants. Factors contributing to head-on collisions include speeding, distracted driving, and driving under the influence of alcohol or drugs. These collisions are particularly dangerous because the combined speed of both vehicles increases the impact force. Safety features in vehicles, such as airbags and crumple zones, can help reduce injuries, but the risk remains high. Proper road design and signage can also play a role in preventing these accidents.
