What Factors Can Lead to Head-on Collisions on Undivided Roads?

Head-on collisions often occur when a vehicle crosses the center line into oncoming traffic. This can happen due to loss of control, distraction, unsafe passing, or sudden steering maneuvers.

On undivided roadways, there is limited physical separation between directions of travel, which can increase the risk of severe impacts when a vehicle drifts out of its lane. Investigators typically review skid marks, vehicle damage, and roadway layout to determine how a crossover occurred. Speed, visibility, and driver behavior are also commonly examined in multi-vehicle crashes. Witness statements and nearby surveillance footage can help clarify the sequence of events leading up to a head-on impact.
