Road Worthiness






Roadworthiness Checks



Enforcement Officers regularly carry out vehicle roadworthiness checks on Northern Ireland´s roads to ensure that vehicles are roadworthy and comply with relevant Construction & Use requirements. Generally vehicles are stopped and directed into a check site or area designated safe to conduct mechanical inspections. Enforcement Officers can exercise powers to direct vehicles up to 10 miles for such purposes. Once at the check site your vehicle will be examined by a Vehicle Examiner.
