California has more registered motorcycles than any other state, and while riding offers freedom and excitement, it also comes with serious risks. Motorcycle riders are far more vulnerable in collisions, and even minor crashes can lead to catastrophic injuries. Below are the 10 leading causes of motorcycle accidents in California, based on traffic safety data and accident reports.
1. Left-Turn Collisions
The most common type of motorcycle accident occurs when a car makes a left turn in front of an oncoming rider. Drivers often misjudge motorcycle speed and distance.

2. Lane Splitting Accidents
Although lane splitting is legal in California, it can be dangerous when drivers change lanes without looking or when riders speed between cars in congested traffic.

3. Distracted Drivers
Texting, eating, or using a GPS causes drivers to miss seeing motorcycles, leading to serious collisions.
4. Speeding
Excessive speed reduces reaction time and increases the severity of crashes, especially for unprotected motorcyclists.
5. Unsafe Lane Changes
Drivers who fail to check blind spots often collide with motorcycles, which are harder to see than cars.
6. Driving Under the Influence (DUI)
Alcohol and drug use remain significant factors in both rider and driver accidents.

7. Road Hazards
Loose gravel, potholes, oil spills, and uneven pavement pose a greater threat to motorcycles than cars.

8. Rear-End Collisions
When drivers follow too closely, they may rear-end motorcycles at stoplights or in traffic, often throwing riders from their bikes.
9. Weather Conditions
Rain, fog, or poor visibility increase the risk of motorcycle accidents, especially on California’s coastal highways.
10. Inexperienced Riders
Lack of proper training or safety gear contributes to crashes involving new or unlicensed motorcyclists.
