Truck Talk: Commercial Bus Accidents

Watch this Truck Talk segment on YouTube

Commercial buses, including charter buses, intercity carriers like Greyhound, and contracted shuttle services, operate under a specific set of federal safety rules that differ from those governing standard passenger cars. When a bus crash occurs in Kentucky, determining who is responsible and what evidence to gather requires understanding how those rules work and who had the duty to follow them.

Federal Rules That Govern Commercial Buses

Commercial buses with a gross vehicle weight rating over 10,000 pounds, or designed to carry nine or more passengers for compensation, fall under FMCSA regulations, the same federal body that oversees large trucks. Bus drivers must hold a valid Commercial Driver’s License with a passenger endorsement. Under 49 CFR Part 391, bus drivers must pass medical examinations, maintain clean driving records, and meet the same drug and alcohol testing requirements as truck drivers.

Hours-of-service rules under 49 CFR Part 395 limit bus drivers to 10 hours of driving after eight consecutive hours off duty. This differs from the 11-hour limit for truck drivers. A bus carrier that schedules drivers for routes that push against these limits creates a foreseeable crash risk, and that scheduling record is obtainable through litigation.

Bus Crash Statistics and Why Passengers Are Vulnerable

Commercial bus crashes cause serious injuries at higher rates than many people expect. In 2023, large trucks and buses together were involved in hundreds of thousands of police-reported crashes nationwide, according to NHTSA. When a bus rolls over or collides with another large vehicle at highway speed, passengers face unique risks: buses are not required to have seat belts in all configurations, interior surfaces can cause serious secondary impact injuries, and roof crush in a rollover is a recognized hazard.

Attorney Jon Hollan has noted that the lack of seat belt requirements on older commercial buses means passengers are often ejected or thrown against interior surfaces in crashes that would be survivable in a properly restrained vehicle. This is a regulatory gap that becomes relevant to injury severity in litigation.

Who Can Be Held Responsible in a Kentucky Bus Crash

Bus crash liability in Kentucky can extend to multiple parties:

• The bus driver, for fatigue, distraction, speeding, or violating federal safety rules
• The bus company, for negligent hiring, improper driver supervision, or scheduling routes that force hours-of-service violations
• The maintenance contractor, if a mechanical failure such as brake failure or tire blowout contributed to the crash under 49 CFR Part 396
• The entity that contracted the bus service, such as a tour company or employer, if it selected a carrier with known safety deficiencies

Kentucky Bus Corridors and Common Crash Locations

Interstate charter and intercity bus routes in Kentucky run heavily along I-65 between Louisville and Nashville, I-64 between Louisville and Lexington, and I-75 between Lexington and Cincinnati. These corridors carry both freight trucks and passenger buses side by side at highway speeds. Crashes involving buses on these routes often involve rear-end collisions from following trucks, sideswiping during lane changes, and single-vehicle rollovers when a driver overcorrects after drifting.

Kentucky State Police crash data shows that interstate crashes on I-64 and I-65 alone account for thousands of collisions annually, with fatal crashes concentrated at high-speed interchange zones. Bus crashes in these areas are particularly serious because of the number of people who may be injured in a single incident.

Evidence That Matters in Commercial Bus Crash Cases

The same electronic data systems that matter in truck crashes apply to commercial buses. ELD records show hours-of-service history. Driver qualification files under 49 CFR Part 391 document whether the driver met federal standards at the time of hire. Carrier safety ratings on the FMCSA’s Safety Measurement System reflect prior violations. Dashcam footage, if present, provides direct evidence of driver behavior. All of this data must be preserved through a written legal hold demand sent immediately after the crash. More on how this process works appears in the Truck Talk episode on black box data and in the truck accident practice area.

Medical Certification and Bus Driver Fitness

Bus drivers operating under FMCSA rules must maintain current medical certification, just like truck drivers. Under 49 CFR Part 391, drivers must be medically examined by a certified medical examiner and carry that certificate with them. Conditions such as uncontrolled hypertension, seizure disorders, or vision impairments can disqualify a driver from holding a valid medical certificate.

When a bus driver medical condition is suspected as a contributing cause of a crash, the driver’s medical examiner records and any medical variance documentation become key evidence. Carriers who place drivers on routes without confirming their current medical certificate status face direct liability for negligent entrustment. Crashes on I-64 and I-65 in Kentucky involving charter buses sometimes reveal medical certification lapses that carriers failed to catch before the driver was assigned to a multi-hour route.

Bus crash cases in Kentucky also benefit from early preservation of any video footage from inside the bus. Many commercial buses now carry passenger-facing and forward-facing cameras as standard equipment. These cameras record the driver’s behavior, distraction events, and the road conditions ahead in real time. If a bus company fails to preserve that footage after being put on notice, Kentucky courts may allow an adverse inference instruction telling the jury it may assume the footage would have been damaging to the carrier’s case.
