Commercial vehicle making a two-lane wide right turn, passenger vehicle on the right

These accidents happen when a commercial vehicle makes a wide right turn on a road with two lanes traveling in the same direction without straddling both lanes and collides with a vehicle in the right lane.

In this diagram, Vehicle A is making a wide right turn from the left lane when it collides with Vehicle B, which is in the right lane.

  • Vehicle "A" = 75%

  • Vehicle "B" = 25%

The rules of the road

Commercial vehicles on two-lane streets must signal and straddle both lanes in order to make a wide right turn. Drivers must not overtake a turning commercial vehicle. Therefore, Vehicle A would be 75% responsible and Vehicle B would be 25% responsible. Responsibility can shift to the passing vehicle in the right lane if it attempts to pass the commercial vehicle and the commercial vehicle is signaling and straddling both lanes.
