What can I do after a hit-and-run with a semi truck?

Sometimes the driver never knew

An 80,000-pound rig can sideswipe a car merging on its right, or drag a bumper during a lane change, and the driver may never feel it. Other times a tire tread or a chunk of load flies off and the truck is a mile gone before anything lands. And sometimes the driver knows and just keeps rolling.

Whatever happened, the law in most places still treats leaving the scene of an injury crash seriously, and you still may have a claim. The job right now is to identify the truck.

Report it right away

Call 911 from the scene if you can. A prompt police report matters twice: it starts the search, and many insurance policies make a timely report to police a condition of paying an uninsured motorist claim for a hit-and-run. The exact rules differ by state and by policy, so read yours or have a lawyer read it.

Tell your own insurer too, as soon as your policy requires.

How a semi gets traced

Semis are big, marked and tracked. That helps you.

• Company name and USDOT number on the cab door, even a partial number
• Trailer number, fleet logo, reefer unit brand, flatbed vs. dry van
• Plate state and any letters you caught
• Dash cam footage from your car or another driver's
• Traffic, toll and business cameras along the route
• Weigh station, fuel stop and truck stop cameras down the road
• Witnesses who followed or called it in

If the truck is never found

Uninsured motorist (UM) coverage on your own auto policy is often the main source of payment in a true hit-and-run. Some states and policies add requirements for a phantom vehicle, such as physical contact between the vehicles or an independent witness, especially when debris or a near-miss caused the crash rather than a direct hit.

Debris cases have their own wrinkles. Our page on truck tire debris accidents uses a California example to show how these claims can play out.

If you were driving a truck yourself when a hit-and-run rig took you out, workers' comp may also be in the picture. That's covered elsewhere in our library.

If the truck turns up later

Sometimes police or an investigator track the truck down days or weeks later through a camera, a fuel receipt, or a tip. At that point the case can shift from an uninsured motorist claim to a regular claim against the carrier and its insurance.

That's another reason to move fast. Trucks carry ELDs, and many carry dash cams and GPS tracking that can place a specific rig at a specific spot and time. Those records aren't kept forever, and a carrier has little reason to hold onto them unless someone asks in writing.

Keep a simple log of every call, claim number and name you deal with. If the case changes direction, that record saves time.
