ROAD TRAFFIC AND VEHICLES
This Order prescribes a type of 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). This means that devices of this type can be approved by the Department of the Environment and the record produced from those approved devices can then be adduced as evidence in proceedings for certain road traffic offences when accompanied by an appropriate signed certificate as to the circumstances of its production. The Order permits the use of devices that record the time it takes for a vehicle to travel between two points on a road by manual activation and which are capable of measuring the distance between those two points by means of the odometer pulses of the vehicle to which they are fitted.
