Hazardous protrusions are prohibited on new and in-service vehicles and are controlled by a number of legal means.

Many vehicle accessories can become hazardous if not installed appropriately including bull bars, radio antennae, winches, bonnet adornments, and fishing rod holders - to name a few.

The legislation is not limited to the front of a vehicle but includes the rear of the vehicle eg - towbars, spare wheel carriers and interior fittings, and the side of the vehicle.

External or internal protrusions

No vehicle shall be equipped with:

  • any object or fitting that is technically essential to the vehicle unless its design, construction, and conditions and the manner in which it is affixed to the vehicle are such as to reduce to a minimum the risk of bodily injury to any person
  • any object or fitting which, because it is pointed or has a sharp edge, is likely to increase the risk of bodily injury to any person
  • any bumper bar the end of which is not turned towards the body of the vehicle to a sufficient extent to avoid any risk of hooking or grazing.
