Hanger Lane and the A40
The gyratory combines a high volume of merging traffic with several lanes and limited sightlines, and the A40 approaches it at speed from both directions. Shunts and side-swipes are routine, and multi-vehicle incidents are not unusual.
It is a poor place to be standing next to a damaged car. If the vehicle can be moved and it is safe to do so, get it off the gyratory before anything else. If it cannot, stay well clear of live lanes and call 999.
For the recovery itself, the constraint is where a truck can safely stop and load. Sometimes that means the vehicle is moved a short distance first, and sometimes it means waiting until traffic can be managed.
