Driving a massive commercial truck while fatigued is incredibly dangerous. We know this, and the Federal Motor Carrier Safety Administration knows this. That is exactly why commercial drivers are heavily restricted on the number of hours they can legally drive by a strict set of rules known as Hours of Service regulations.

Understanding Hours of Service Rules

These specific federal regulations are codified in 49 C.F.R. Section 395. They dictate the maximum allowable driving time, the minimum required rest periods, and the strict weekly caps on total duty hours. When a driver intentionally ignores these regulations, it becomes a federal offense. If that specific offense causes your catastrophic crash, a judge and jury will hear all about it. Truck drivers frequently describe experiencing extreme pressure from their corporate employers to keep rolling regardless of the heavy hours they have already logged.

The Electronic Logging Device Mandate

Long gone are the days of trucks rolling down the highway with easily manipulated handwritten logs showing illegal driving hours. The FMCSA put a definitive end to that practice. Under 49 C.F.R. Section 395.8, commercial drivers are now legally required to install an Electronic Logging Device. This ELD plugs directly into the truck’s engine diagnostics and permanently records their active driving time.

An advanced ELD automatically records critical data such as:

• The exact moment the truck engine is turned on or off.
• Every minute the truck is physically moving in gear.
• The precise number of miles driven during a shift.
• The exact length of time the driver has been actively on duty.

An ELD is one of the absolute best forms of objective evidence in a truck accident case. However, if it is not preserved properly by an aggressive attorney, this digital data can be overwritten and gone forever. If your accident involves a commercial truck, you do not want to take any chances with ELD data disappearing.
