The Federal Rules That Decide Truck Cases
Alcohol and drugs
A commercial driver may not use alcohol within four hours of going on duty or have any measurable concentration while on duty (49 CFR 392.5), and may not drive under the influence of Schedule I drugs, amphetamines or narcotics (49 CFR 392.4). Four of the eight fatal crashes recorded in the Kaysville area since 2018 involved an impaired driver.
Hours behind the wheel
A property-carrying driver is limited to 11 driving hours after 10 consecutive hours off duty, inside a 14-hour window, and must keep an electronic log (49 CFR 395.3). A driver finishing a shift on the Ogden-to-Salt Lake run meets the worst of the I-15 slowdown right through Kaysville, and the log is what shows how long he had been driving.
Identifying the carrier
Every commercial vehicle must display the operating carrier’s name and USDOT number on both sides, legible from 50 feet, and a leased truck running under another company’s name must add “operated by” with the real carrier (49 CFR 390.21). A single photograph of the door often establishes who actually pays.
Coverage limits
Interstate carriers hauling general freight must carry at least $750,000 in liability coverage, and hazardous loads require more: $1,000,000 for many, $5,000,000 for certain bulk substances (49 CFR 387.9). Tankers running I-15 fall in the higher tiers. See our Utah truck claims guide.
If the truck does not stop
Kaysville-area records show 180 hit-and-run crashes since 2018. Uninsured motorist coverage may respond, but where the truck never touched your vehicle, Utah Code § 31A-22-305(6) requires clear and convincing corroboration beyond your own testimony, so write down anything you read on the door.
