Motorcycles occupy a much smaller visual profile than cars and trucks, making them particularly vulnerable to being overlooked in a vehicle's blind spots. These blind spots—areas around a vehicle that cannot be seen in the side or rearview mirrors—are especially dangerous during lane changes, merges, and turns. Studies show that approximately 40% of motorcycle accidents involve another vehicle violating the motorcyclist's right of way, with blind spot collisions representing a significant portion of these crashes.
California drivers have a legal duty to check their blind spots before making any lateral movement on the roadway. This includes physically turning their head to look over their shoulder, not just relying on mirrors. Despite this requirement, many drivers fail to take this simple precaution, leading to serious and often fatal motorcycle accidents. The problem is compounded by distracted driving, as drivers checking their phones or adjusting controls are even less likely to notice a motorcycle in their blind spot.
For motorcyclists, the consequences of a blind spot accident can be catastrophic. Unlike occupants of enclosed vehicles, riders have no protective barrier between themselves and the road or other vehicles. When a car suddenly merges into a motorcycle's lane, the rider may be struck directly, knocked off balance, or forced to take evasive action that results in a crash. Common injuries include traumatic brain injuries, spinal cord damage, broken bones, road rash, and internal organ damage.
