What discovery should be prioritized in a common carrier bus case?

Onboard video and event data recorder output, operator training materials, the operator's personnel and complaint history, and vehicle maintenance records are typically the highest-priority discovery targets.

How does the common carrier standard affect the comparative fault argument?

The heightened duty requires the operator to anticipate that passengers, especially elderly, disabled, or burdened passengers, may not be able to secure themselves quickly, which counters defense arguments that the passenger's own conduct was the primary cause.

Should Public Records Act requests be used alongside formal discovery?

Yes, because LACMTA is a public entity, Public Records Act requests can be pursued independently and in parallel with formal litigation discovery to obtain policies, training materials, and prior incident records.

Does the common carrier duty apply to boarding and exiting, not just movement while riding?

Yes, the heightened duty extends to the boarding and exiting process, including ramp deployment, curb alignment, and door operation, not solely to the vehicle's movement while passengers are seated or standing.

Common Carrier Bus LACMTA California Doctrine: The Utmost Care Standard

The common carrier bus LACMTA California cases turn on is not the ordinary negligence standard most personal injury attorneys apply by default. Civil Code section 2100 imposes a materially higher duty, and failing to instruct the jury, and structure discovery, around that heightened standard is one of the most common strategic errors in transit litigation.

The Statutory Standard and Why It Matters

Civil Code section 2100 requires a carrier of persons for reward to use the utmost care and diligence for the safe carriage of its passengers, to provide everything necessary for that purpose, and to exercise a reasonable degree of skill. California courts, and CACI No. 902, translate this into a requirement that common carriers do all that human care, vigilance, and foresight reasonably can do under the circumstances to avoid harm to passengers. This is a demonstrably higher bar than the reasonable person standard applied in an ordinary negligence case, and counsel should request the specific common carrier jury instruction rather than allowing the case to be tried under a generic negligence framework.

Establishing a Prima Facie Case Through Unusual Movement

California courts have recognized that where a common carrier's passenger is injured and an unusual or violent movement of the vehicle caused the injury, that evidence alone can establish a prima facie case of negligence, shifting the practical burden to the carrier to explain the movement. This principle is particularly useful in sudden-stop and sharp-turn cases, where there may be no independent witness testimony beyond the plaintiff's own account and onboard video. Framing the case around this evidentiary principle from the outset shapes both the discovery plan and the eventual jury instructions.

Discovery Priorities Specific to Common Carrier Cases

Litigation against LACMTA as a common carrier should prioritize a defined set of records, and because LACMTA is also a public entity, these requests should be pursued both through formal litigation discovery and, where applicable, through California Public Records Act requests submitted independently and in parallel.

Onboard video and event data

Onboard video from all cameras and any event data recorder output covering speed, braking force, and acceleration at the time of the incident.

Operator training and history

Operator training materials and policies addressing passenger safety during acceleration, braking, and turns, plus the operator's personnel file and any prior safety violations or passenger complaints.

Vehicle maintenance records

Maintenance records for the specific vehicle, particularly for claims involving ramp malfunctions or door mechanisms.

Keeping the Heightened Standard in Front of the Jury

A recurring defense tactic is to argue that a passenger's fall resulted from their own failure to hold on, inviting the jury to apply an ordinary contributory negligence framework. Plaintiff's counsel should meet this directly by emphasizing that the common carrier's heightened duty exists precisely because passengers, particularly those who are elderly, disabled, or standing with packages or children, cannot always secure themselves quickly, and the operator is required to anticipate that reality. Counsel should request CACI No. 902 and any related instructions rather than accepting a generic negligence package, object on the record if the court declines the heightened-duty instruction to preserve the issue for appeal, and have any transit operations expert frame their opinions around the utmost care standard rather than a generic reasonableness analysis.
