Highway merge accidents occur for various reasons, but certain factors appear repeatedly in California collision reports. Understanding these common causes can help establish liability and strengthen your injury claim. Failure to yield right-of-way is the leading cause of merge accidents, as drivers entering the highway often misjudge the speed of oncoming traffic or fail to wait for a safe gap. California Vehicle Code Section 21804 requires drivers entering a highway to yield to traffic already on the roadway.
Speeding is another major contributor to merge zone collisions. When drivers exceed posted speed limits or drive too fast for conditions, they have less time to react to merging vehicles and require greater stopping distances. Distracted driving—including texting, phone calls, eating, or adjusting navigation systems—significantly increases merge accident risk. Even a momentary lapse in attention can result in a serious collision when vehicles are traveling at highway speeds.
Blind spot errors cause numerous merge accidents each year. Large trucks, SUVs, and vehicles with poor visibility create substantial blind zones where other vehicles disappear from view. Drivers who fail to check blind spots before merging or changing lanes may collide with vehicles they never saw. Additionally, inadequate acceleration when merging onto highways creates dangerous speed differentials that can lead to rear-end collisions or force other drivers to make sudden lane changes.
