California offers some of the nation’s best cycling weather, but it also presents unique dangers for riders. Understanding the most common causes of bicycle crashes can help cyclists stay safer—and recognize when another party may be legally responsible.

Distracted Drivers

Texting, GPS use, eating, and other distractions reduce reaction time and frequently contribute to collisions involving cyclists.

Left-Turn Collisions

One of the most serious accidents occurs when a motorist turns left across the path of an oncoming cyclist.

Right Hook Accidents

Drivers turning right often underestimate a cyclist’s speed or fail to check bike lanes before making the turn.

Dooring Accidents

A parked driver opening a vehicle door into the path of a cyclist can cause severe injuries, particularly in urban areas.

Unsafe Lane Changes

Motorists who fail to check mirrors or blind spots before changing lanes frequently collide with cyclists riding legally alongside traffic.

Poor Road Maintenance

Potholes, uneven pavement, broken storm drains, loose gravel, and defective roadway design can all contribute to serious crashes.

Government agencies may sometimes be responsible when dangerous road conditions cause injuries.

Speeding

Higher vehicle speeds dramatically increase the severity of injuries sustained by cyclists.

Driving Under the Influence

Alcohol and drug impairment continue to play a significant role in serious bicycle accidents throughout California.

How Cyclists Can Reduce Risk

  • Wear a properly fitted helmet
  • Use front and rear lights
  • Ride predictably
  • Follow traffic laws
  • Stay visible
  • Avoid riding in blind spots
  • Scan constantly for turning vehicles

Know Your Rights

Even careful cyclists cannot prevent every crash. If another person’s negligence caused your injuries, California law may allow recovery for medical expenses, lost income, bicycle damage, and pain and suffering.
