Different Types of Bus Accidents and Who May Be Liable in California
When people think about bus accidents, they often picture a bus colliding with another vehicle. While those crashes can cause serious injuries, they are only one type of accident involving buses. Passengers can be injured when a driver stops suddenly, pedestrians can be struck as a bus turns through an intersection, and mechanical problems can contribute to a collision.
A recent California school bus crash shows how quickly an unexpected situation can lead to injuries. On August 27, 2026, a Placer County school bus carrying 22 students crashed into a concrete guardrail in Yuba County. According to the California Highway Patrol, the bus moved to the right when an oncoming vehicle approached, causing the rear of the bus to hit the guardrail. One student suffered minor injuries, and investigators were reviewing dashcam footage as they worked to determine what happened.
The investigation into that crash does not establish who was at fault. It does, however, illustrate why bus accidents require a close look at the circumstances surrounding the incident. The type of accident, the actions of the people involved, and the condition of the bus can all affect who may be legally responsible.
Bus-to-Vehicle Collisions
Collisions between buses and passenger vehicles are among the most familiar types of bus accidents. They can occur at intersections, when a bus changes lanes, as it pulls away from a stop, or when another vehicle fails to yield.
Determining who caused the crash requires more than simply identifying which vehicles made contact. Investigators may need to establish where each vehicle was traveling, whether a driver had the right of way, and whether either driver violated a traffic law. Traffic signals, vehicle speeds, lane positions, road conditions, and witness accounts can all help establish what happened.
A passenger injured in the crash may have a claim even though they were not driving either vehicle. Depending on the circumstances, the actions of the bus driver, another motorist, or both may become relevant to the claim.
Bus Accidents Involving Pedestrians
Buses frequently travel through areas with heavy pedestrian traffic, including intersections, downtown streets, transit centers, and residential neighborhoods. A pedestrian may be struck when a bus turns, pulls away from a stop, or approaches a crosswalk.
These accidents can cause catastrophic injuries because pedestrians have little protection against the force of a large vehicle. In July 2026, for example, a Long Beach Transit bus struck and fatally injured a pedestrian while making a left turn. Investigators said they did not initially believe speed, distracted driving, or impairment played a role.
A pedestrian accident does not automatically mean the bus driver or transit agency is liable. Investigators still need to determine how the collision occurred and whether the driver or another party failed to act reasonably.
Passengers Injured Inside a Bus
A bus does not have to collide with another vehicle for a passenger to suffer a serious injury. Sudden braking, acceleration, swerving, or sharp turns can throw passengers from their seats or cause people who are standing to lose their balance.
These injuries can be especially serious for older adults and people with mobility limitations. A passenger may strike a seat, pole, window, or another part of the bus during a sudden maneuver, resulting in injuries that require substantial medical treatment.
The circumstances surrounding the driver’s actions can become important in these cases. A sudden stop may have been necessary to avoid a collision, for example, while an unnecessarily abrupt maneuver could raise different questions about whether the driver operated the bus safely. California’s commercial driver guidance emphasizes smooth starting and stopping and giving passengers time to sit down or brace themselves before the bus moves.
Accidents While Boarding or Exiting
Passengers can also suffer injuries while getting on or off a bus. A person may fall because of a problem with the steps, door, ramp, or other equipment. In some situations, a passenger may be injured if the bus begins moving before they have safely cleared the doorway.
These accidents can raise different liability questions from a typical traffic collision. Investigators may need to determine whether the equipment was working properly, whether the driver could see the passenger, and whether the bus operator took reasonable precautions before moving.
When a mechanical or equipment problem contributes to the injury, responsibility may extend beyond the driver. The circumstances could involve a transit agency, maintenance provider, or manufacturer, depending on what caused the problem.
Bus Rollover and Loss-of-Control Accidents
A bus can also cause widespread injuries when the driver loses control or the vehicle rolls over. These accidents may result from excessive speed, unsafe maneuvers, hazardous road conditions, another driver’s actions, or a mechanical failure.
Because a bus can carry many passengers at once, a single loss-of-control accident can injure multiple people. Determining the cause may require investigators to examine the driver’s decisions as well as the condition of the roadway and vehicle.
Mechanical Failures and Poor Maintenance
Mechanical problems can create another category of bus accidents. Brake failures, tire problems, steering defects, and other equipment issues can make it difficult for a driver to control the vehicle or stop safely.
When a mechanical problem contributes to an accident, determining liability can become more complicated. A transit agency may have responsibility for maintaining its vehicles, while a private maintenance company could be responsible for defective repairs. In some cases, a manufacturer may also face a product liability claim if a defective component caused the failure.
Maintenance records, inspection reports, repair records, and information about previous problems with the vehicle may help establish whether someone knew or should have known about a dangerous condition.
Who May Be Liable for a Bus Accident?
The party responsible for a bus accident depends on what caused the injury. A negligent bus driver may be responsible for unsafe driving, while another motorist could be liable if their actions caused the bus to crash. A transit agency, maintenance company, or vehicle manufacturer may also become involved when their conduct or a defective product contributes to an accident.
Claims involving public transportation can present additional legal requirements. California Courts explains that people seeking compensation from a government agency generally must submit an administrative claim before filing a lawsuit. For many personal injury claims against a public entity, the claim generally must be presented within six months of the injury, although exceptions can apply.
What Should You Do After a Bus Accident?
If you are injured in a bus accident, seek medical attention promptly. Even when an injury does not seem serious immediately after the incident, symptoms can develop later. Medical records can also provide important documentation of the injuries and treatment associated with the accident.
If your condition allows, gather information about what happened while the details are still fresh. Photographs of the scene and your injuries, witness contact information, the bus route or vehicle number, and copies of medical records may all become useful later.
You should also find out whether a public agency operates the bus. Public transportation claims can involve shorter deadlines and additional procedures, so waiting too long to determine where and how to file a claim could put your rights at risk.
