Yes. Commercial truck drivers and trucking companies operate under an additional layer of federal safety regulations that don't apply to everyday drivers. These rules cover things like hours-of-service limits (how long a driver can be on the road before resting), vehicle maintenance and inspection requirements, and driver qualification standards.

This matters in a crash case because a violation of these federal rules can be important evidence of negligence. Some of the records that can come into play include:

• Electronic logging device (ELD) data
• Driver qualification files
• Vehicle inspection and maintenance records
• Drug and alcohol testing records

We intentionally aren't listing specific regulatory numbers or thresholds here, since those rules are detailed and can change. What we can tell you is that trucking companies often move quickly to preserve evidence that helps them and may not be as quick to preserve what helps you. If you've been in a crash with a commercial truck anywhere in Metro Detroit, time matters.
