ROAD TRAFFIC AND VEHICLES

This Order prescribes a speed detection device for the purposes of Article 23 of the Road Traffic Offenders (Northern Ireland) Order 1996 (speeding offences etc: admissibility of certain evidence). The device prescribed captures and records images of motor vehicles at two positions on the road and calculates the average speed of the vehicles between those positions.
