You may see this in a crash report, a trucking company letter, or a lawyer's request for records: "possible violations of FMCSA regulations" or "subject to FMCSA compliance." That usually points to the Federal Motor Carrier Safety Administration's safety rules for commercial trucks, buses, drivers, and motor carriers. These rules cover things like hours-of-service, driver qualifications, vehicle inspection and maintenance, cargo securement, and drug and alcohol testing.

After a serious truck crash, those rules can become key evidence fast. A violation may help show negligence or support a claim that a carrier failed to supervise, train, inspect, or keep an unsafe truck off the road. On Connecticut highways, that can matter a lot when conditions turn suddenly dangerous, including black ice on bridges over the Connecticut River where road-surface warning may come too late.

The clock starts running right away. Some FMCSA-required records, including certain log and supporting documents, may be kept for only a limited time, and electronic data can be overwritten. A prompt preservation letter can help protect driver logs, dashcam footage, inspection records, and onboard data before they disappear. In Connecticut, the general injury deadline under Conn. Gen. Stat. § 52-584 (2024) is usually two years, but waiting that long can cost you crucial proof. FMCSA regulations often provide the roadmap for what evidence should exist - and what may already be at risk of being lost.
