Can a truck be liable for a side underride collision in Georgia?

· 3 min read

A side underride collision happens when a vehicle strikes the side of a long trailer and slides beneath it, often where the gap between the trailer body and the road leaves a car’s windshield and roofline exposed to the trailer’s edge. The truck side can be liable in Georgia, though the analysis differs from rear underride because the safety-equipment landscape for trailer sides is less developed.

Why side underride is a distinct problem

Unlike the rear of a trailer, where impact guards are generally required, trailer sides have historically lacked a comparable mandated guard. The long, open span between the wheels and the kingpin can let a car pass under the trailer in a side impact, with the trailer’s lower edge striking the passenger compartment. Because there is no equivalent long-standing federal requirement for side guards on most trailers, a claim cannot usually rest on the absence of a legally required guard the way a rear-underride claim sometimes can.

That does not foreclose liability. It shifts the focus toward the conduct that put the trailer in the vehicle’s path and toward the trailer’s visibility and condition.

Where liability can come from

In Georgia, side underride cases generally turn on ordinary negligence and the circumstances of the crash:

  • A truck that blocked or crossed a roadway, such as backing across or making a slow turn that left the trailer spanning travel lanes in the dark.
  • Inadequate reflective tape, lighting, or conspicuity markings that made the trailer’s side hard to see at night, which federal rules address through conspicuity requirements.
  • An improperly parked or stopped trailer obstructing a lane.
  • Driver conduct that created the hazard, such as an ill-timed turn into oncoming or cross traffic.

If poor visibility or unsafe positioning of the trailer contributed to the impact, the carrier and driver can be responsible. Conspicuity violations, in particular, can support a negligence theory because the rules exist to make trailers visible and prevent exactly this kind of collision.

How Georgia divides the fault

Responsibility is allocated by percentage among everyone at fault. The striking driver’s own speed, attention, and conduct are weighed alongside the truck’s positioning and visibility, and a claimant who is 50% or more at fault recovers nothing. Investigations look at lighting and reflective markings, the trailer’s location and movement, sight lines, and the time and conditions of the crash.

The bottom line

A truck can be liable for a side underride collision in Georgia, but because mandated side guards are not the established norm, liability usually rests on negligence: an unsafely positioned trailer, a poorly timed maneuver, or inadequate lighting and reflective markings that left the trailer’s side unseen. The striking driver’s conduct is still weighed under Georgia’s percentage-based fault rules.
