😴 Truck Driver Fatigue Laws

Drowsy driving by commercial truck drivers kills thousands of Americans every year. Learn how FMCSA fatigue regulations protect you — and how their violation helps your case.

The Fatigue Crisis in Commercial Trucking

The Federal Motor Carrier Safety Administration estimates that fatigue is a contributing factor in approximately 13% of all commercial truck crashes. A fatigued truck driver behind the wheel of an 80,000-pound vehicle is a catastrophic risk to every motorist on the road. Studies have shown that driving after 18+ hours without sleep produces impairment equivalent to a blood alcohol concentration of 0.08% — the legal limit for drunk driving.

FMCSA Hours of Service Regulations

The Hours of Service (HOS) rules (49 CFR Part 395) are the primary federal tool for combating fatigued driving. For property-carrying drivers (the most common type in interstate commerce):

⏱️
11-Hour Driving Limit

After 10 consecutive hours off duty, a driver may drive for a maximum of 11 hours.

📅
14-Hour On-Duty Window

Driving is prohibited beyond the 14th consecutive hour after coming on duty.

30-Minute Break

A 30-minute break is required after 8 cumulative hours of driving.

🛑
10-Hour Rest Requirement

Drivers must take a minimum of 10 consecutive hours off duty between driving shifts.

📆
60/70-Hour Weekly Limit

Drivers cannot drive after 60 hours on-duty in 7 days, or 70 hours in 8 days.

Despite strict regulations, HOS violations are endemic in the industry. Common schemes include:

Fatigue Violations and Your Case

When we prove a driver was in violation of HOS regulations at the time of your crash, it creates a powerful presumption of negligence. In many states, a statutory violation that causes injury constitutes negligence per se — meaning the defendant is presumed to be negligent without requiring further proof.

Moreover, if we can show the trucking company's dispatchers knew the driver was fatigued and pressured them to continue driving anyway, this opens the door to significant punitive damages against the corporation.

Time Is Critical

ELD data can be overwritten after a certain number of driving days. Contact our attorneys immediately after a crash to issue a spoliation letter before this evidence is gone. Find your state's representation:
