A bus driver may be held liable when careless, reckless, or unlawful driving causes a crash and someone suffers injuries or losses. Liability depends on the driver’s conduct, whether it caused the accident, and the surrounding facts.

Los Angeles is one of California’s largest cities, with public, school, charter, and other buses operating throughout the region. Bus routes run through neighborhoods and commercial areas across Los Angeles, while major roads such as Interstate 5, Interstate 10, U.S. Route 101, and Interstate 405 carry large volumes of traffic. These conditions mean bus accidents can involve passengers, pedestrians, cyclists, and people traveling in other vehicles.

A person injured in one of these incidents may need a Los Angeles bus accident attorney to understand how driver negligence affects a claim. This article explains when a bus driver may be held liable for an accident, what conduct can support a negligence claim, and what evidence may help establish responsibility.

When a Bus Driver Is Distracted

Distracted driving can include texting, using a phone, adjusting controls, eating, or taking attention away from the road. NHTSA reported 3,208 deaths from distracted driving crashes in 2024. If distraction contributes to a collision, it may support a negligence claim. Video footage, witness accounts, phone records, and the driver’s statements may help establish what happened.

Speeding and Other Reckless Driving Behaviors

Speeding can make it harder for a vehicle to stop or avoid hazards. Other reckless behaviors may include tailgating, unsafe lane changes, aggressive turns, or passing. A traffic citation can be useful evidence, but it does not automatically establish liability. Investigators may also review the accident report, video, vehicle data, and witness statements to determine whether the driver caused the crash.

Alcohol or Drug-Impaired Driving

Alcohol and drugs can impair judgment, coordination, reaction time, and attention. A bus driver who operates while impaired may be responsible when that impairment contributes to an accident. Evidence can include chemical testing, police reports, witness observations, and records showing whether the driver was investigated or cited.

Traffic Law Violations

Running a red light, failing to yield, making an unsafe turn, or ignoring another traffic rule can create a dangerous situation. When a violation causes a collision, it may provide evidence of negligence. A driver who runs a red light but does not cause the accident would not necessarily be responsible for another person’s losses.

California law also establishes specific duties for carriers transporting passengers, including requirements involving care, vehicle safety, and reasonable speed.

When a Bus Driver Fails to Protect Passengers

Bus drivers must account for passengers as well as road users. Sudden acceleration, harsh braking, sharp turns, or pulling away before passengers are safely positioned can cause falls and injuries even when no collision occurs. Ordinary bus movement does not necessarily establish negligence. Evidence must show that the driver’s conduct was unsafe under the circumstances.

California Civil Code § 2100 provides that a carrier of persons for reward must use the utmost care and diligence for the safe carriage of passengers and exercise a reasonable degree of skill. This heightened duty may be relevant when evaluating whether a bus driver or carrier took appropriate precautions to protect passengers from injury.

When the Bus Driver’s Employer May Also Be Liable

A bus driver may not be the only responsible party. Under respondeat superior, an employer can generally be responsible for an employee’s negligent conduct when the employee was acting within the scope of employment. A bus company or transit agency may also face claims based on its own conduct, such as negligent hiring, training, supervision, or maintenance. Identifying every responsible party can matter.

What Evidence Can Establish Bus Driver Liability?

Evidence can help connect the driver’s conduct to the accident and injuries. Useful records include:

• Police reports and traffic citations
• Bus or traffic-camera footage
• Passenger and eyewitness statements
• Driver schedules and employment records
• Vehicle or GPS data
• Medical records

Preserving evidence can be important when video or electronic records may be overwritten.

Key Takeaways

• Distraction, speeding, impairment, and traffic violations can support negligence claims.
• Unsafe braking, turning, or acceleration can injure passengers without a collision.
• An employer may also be responsible for an employee’s negligence on the job.
• Video, witness statements, and police records can help establish fault.
