The most common causes of rideshare accidents in California are distracted driving, driver fatigue, speeding, and GPS-related inattention. Because Uber and Lyft drivers depend on smartphone apps to accept rides, navigate, and communicate with passengers, the distractions built into the rideshare model make these crashes different from typical car accidents and create specific legal arguments for injured victims.

How Does App Use Contribute to Rideshare Accidents in California?
Rideshare drivers are required by the job to interact with their phones throughout every trip, creating a persistent source of distraction that is not present in ordinary driving.
- Accepting ride requests requires the driver to look at and tap the app while already in motion
- GPS navigation prompts demand frequent screen glances, particularly in unfamiliar areas
- Communicating with incoming passengers through the app while driving is a direct form of distracted driving
- California Vehicle Code Section 23123.5 prohibits handheld phone use while driving, and rideshare app interactions may violate this law
- Evidence that the driver was interacting with the app at the moment of impact can establish negligence per se
How Does Driver Fatigue Cause Rideshare Accidents?
Many Uber and Lyft drivers work rideshare as a second job or drive late into the night to take advantage of surge pricing, creating significant fatigue-related crash risk.
- California does not impose formal hours-of-service limits on rideshare drivers the way federal law limits commercial truckers
- Drowsy driving impairs reaction time, lane-keeping, and hazard recognition at rates comparable to alcohol impairment
- Drivers who log on during overnight surge periods between midnight and 4 a.m. carry the highest fatigue risk
- Trip records and GPS logs from the rideshare platform document how many consecutive hours a driver was on the app before the crash

What Traffic Violations Most Commonly Lead to Rideshare Crashes?
Standard traffic violations account for a large share of rideshare accidents, but the circumstances of rideshare driving make certain violations especially common.
- Sudden stops or swerves to pick up passengers at undesignated locations cause rear-end and sideswipe collisions
- Speeding between rides to maximize earnings and minimize time between fares is a documented rideshare driving pattern
- Illegal U-turns and wrong-way entry onto one-way streets occur frequently when drivers follow GPS directions blindly
- Double-parking and stopping in travel lanes to pick up or drop off passengers creates rear-end crash hazards for following traffic
How Do These Causes Affect Your Injury Claim After a Rideshare Crash?
The cause of the crash directly determines which legal theories apply to your claim, which evidence to preserve, and whether the rideshare company itself shares liability beyond its insurance policy.
- App distraction evidence, including trip logs and interaction timestamps, must be requested from Uber or Lyft immediately after the crash
- Fatigue claims are supported by the driver's full trip history showing hours worked before the accident
- Traffic violation evidence in police reports creates a strong negligence per se foundation for your claim
- If Uber or Lyft's platform design required the distraction that caused the crash, the company itself may face direct liability
