The Federal Hours of Service Rules: How Truck Driver Fatigue Leads to Catastrophic Crashes

Federal Hours of Service Rules Exist for a Reason

The Federal Motor Carrier Safety Administration, or the FMCSA, sets strict rules about how long truck drivers can operate their vehicles before mandatory rest. These Hours of Service regulations exist specifically because the trucking industry needed hard limits to protect the public.

Here is what the current rules require:

• The 11-Hour Driving Limit: A truck driver may drive a maximum of 11 hours after completing 10 consecutive hours off duty. Once a driver hits that 11-hour mark, they must stop. No exceptions.
• The 30-Minute Break Requirement: Drivers must take a 30-minute break after 8 cumulative hours of driving without at least a 30-minute interruption.
• The 60/70-Hour Weekly Limit: Drivers cannot exceed 60 hours on duty in any 7-day period, or 70 hours in any 8-day period. This cap prevents drivers and their employers from simply running nonstop across an entire work week.
• The 34-Hour Reset: A driver who reaches their weekly hour limit must take at least 34 consecutive hours off duty before starting a new weekly cycle.

These rules are clear, specific, and legally enforceable. When drivers or trucking companies violate them, they are breaking the law and creating the conditions for catastrophic crashes.

How HOS Violations Affect Your Case

When a fatigued driver causes a crash, a skilled personal injury attorney immediately investigates whether Hours of Service violations played a role.

Driver logs, electronic logging device data, GPS records, fuel receipts, and dispatch communications all tell a story about how long that driver had been on the road before the crash.

If the evidence shows that a driver exceeded their legal driving limits, or that a trucking company pressured drivers to falsify their logs and keep driving, that violation becomes powerful evidence of negligence.

This shifts the narrative from “an accident happened” to “a preventable crash occurred because someone broke federal law.”

Our personal injury lawyer uses HOS violations to demonstrate not only that the driver was at fault but also that the trucking company behind them shares direct responsibility.
