How do I know if the truck driver was violating hours-of-service rules?

Electronic logging devices (ELDs) automatically record the driver's duty status, driving time, and rest periods. Your attorney can subpoena ELD data from the trucking company during litigation. This data shows whether the driver exceeded maximum driving hours, skipped required breaks, or falsified their driving time. ELD data is one of the most important pieces of evidence in fatigue-related truck accident cases.

Can a trucking company be held liable for hiring an unsafe driver?

Yes. Federal regulations require trucking companies to investigate a driver's background before hiring, including reviewing their driving record, prior employment history, and drug and alcohol testing history. If a company hires a driver with a history of accidents, violations, or failed drug tests without adequate review, the company can be held independently liable for negligent hiring.

Does a federal safety violation automatically prove the truck driver was at fault?

Not automatically, but a regulatory violation is strong evidence of negligence. To establish liability, you must also show that the violation contributed to causing the accident and your injuries. For example, if a driver exceeded hours-of-service limits and fell asleep at the wheel, the HOS violation combined with the driver fatigue evidence strongly supports a negligence claim.

Federal Trucking Regulations and How Violations Affect Your Illinois Accident Case

Last Updated: April 2, 2026

**The FMCSA enforces federal trucking regulations covering driver qualifications, maintenance, and hours of service.** Violations of these regulations constitute negligence and support your lawsuit against the trucking company. Citations for violations are admissible as evidence.

Federal regulations govern nearly every aspect of commercial trucking — from how many hours a driver can operate to how a truck must be maintained and loaded. When a trucking company or driver violates these regulations and causes an accident, those violations are powerful evidence of negligence in an Illinois personal injury or wrongful death case. Understanding which federal rules apply and how they relate to your case is essential to building a strong claim.

Hours of Service (HOS) Regulations

Fatigue is one of the most common causes of truck accidents. The FMCSA’s hours-of-service rules limit how long commercial drivers can operate before taking mandatory rest breaks. Property-carrying drivers may drive a maximum of 11 hours after 10 consecutive hours off duty, may not drive beyond the 14th consecutive hour after coming on duty, and must take a 30-minute break after 8 cumulative hours of driving. Violations of these rules — driving beyond the maximum hours, falsifying log entries, or skipping required breaks — are direct evidence of negligence. Electronic logging devices (ELDs), which are now required on most commercial vehicles, record driving time automatically and are critical evidence in fatigue-related truck accident cases.

Drug and Alcohol Testing Requirements

The FMCSA requires commercial drivers to undergo drug and alcohol testing at several points: pre-employment, randomly during employment, after any accident meeting certain severity thresholds, when a supervisor has reasonable suspicion, and upon returning to duty after a violation. Trucking companies are required to maintain records of all testing and to remove drivers from service who test positive. Failure to comply with these testing requirements — or failure to act on positive results — can establish negligence by both the driver and the trucking company.

Vehicle Maintenance and Inspection Standards

Federal regulations require trucking companies to systematically inspect, repair, and maintain all commercial motor vehicles under their control. Drivers must conduct pre-trip and post-trip inspections and report any deficiencies. Companies must address reported deficiencies before allowing the vehicle back on the road. Annual inspections by qualified inspectors are also required. When a truck accident is caused by a mechanical failure — brakes, tires, steering, lights — the truck’s maintenance records and inspection reports are essential evidence. Missing or incomplete records may themselves be evidence of regulatory violations.

Cargo Loading and Securement Rules

FMCSA cargo securement rules specify how different types of cargo must be loaded, distributed, and secured to prevent shifting during transport. Overloaded trucks require longer stopping distances and are more prone to tire blowouts and rollovers. Improperly secured cargo can shift during turns or braking, destabilizing the truck or falling onto the roadway. The catastrophic injuries that result from truck accidents are often made worse when cargo loading violations contribute to the crash severity.

Driver Qualification Standards

Federal law sets minimum qualifications for commercial truck drivers, including age requirements, medical certification, road testing, and a valid commercial driver’s license (CDL) with appropriate endorsements. Trucking companies must verify these qualifications and maintain driver qualification files. Negligent hiring — putting an unqualified or unsafe driver behind the wheel — is a separate basis for liability against the trucking company. Prior accident history, traffic violations, and failed drug tests in a driver’s record can all be relevant if the company failed to review or act on this information.

How Regulatory Violations Help Your Case

In Illinois, violations of federal trucking regulations can be used as evidence of negligence. While a regulatory violation alone does not automatically establish liability, it demonstrates that the driver or company failed to meet the safety standards that apply to the trucking industry. Combined with evidence that the violation contributed to the crash, regulatory violations can be compelling evidence for a jury. They also help counter the common defense that the truck driver was simply involved in an unavoidable accident.
