A RUNAWAY trailer sparked a series of incidents at the bottom of the Toowoomba Range last night.
The trailer was being towed by a Toyota Land Cruiser when it became unhinged at the bottom of the Range in the eastward-bound lanes about 7.25pm.
It came to a stop in the outside lane before three vehicles collided with it.
A Hyundai Excel Sprint, the first vehicle to collide with the trailer, and a Nissan Maxima sedan sustained the worst of the damage.
None of the occupants of the vehicles were injured. The eastward-bound lanes were closed for about 25 minutes as emergency crews cleared the scene.
