The vast majority of motorcycle intersection accidents are caused by driver negligence rather than motorcyclist error. The most frequent cause is the 'left-turn accident,' where a vehicle turns left across the motorcyclist's path, violating their right of way. Drivers often claim they 'didn't see' the motorcycle, but failure to observe traffic is itself a form of negligence under California law. Other common causes include drivers running red lights, rolling through stop signs, and making illegal U-turns without checking for oncoming motorcycles.
Distracted driving has become an increasingly significant factor in intersection collisions. Drivers texting, adjusting GPS devices, or engaging with passengers often fail to notice motorcycles approaching intersections. Distracted driving accidents are particularly egregious because they are entirely preventable. Additionally, speeding through intersections reduces a driver's ability to react to motorcycles and increases the severity of any resulting collision. California Vehicle Code requires all drivers to exercise reasonable care and maintain proper lookout for all road users, including motorcyclists.
Poor intersection design and inadequate signage can also contribute to motorcycle accidents. Obstructed sight lines, confusing traffic signals, and poorly maintained road surfaces create hazardous conditions for all vehicles, but motorcycles are especially vulnerable. In cases where road design or maintenance issues contributed to your accident, you may have a claim against the government entity responsible for that roadway in addition to any negligent drivers involved.
