The Government has moved on what it calls "technical problems" in the laws covering breath-testing, speed measurement and weighing devices on the roads.

The Transport Minister, Mark Gosche, introduced a bill yesterday that he said would correct the discrepancies.

He said changes proposed in the Land Transport (Road Safety Enforcement) Amendment Bill would deal with the use of laser and static cameras in prosecutions against speeding drivers in 50 km/h areas, and in areas with temporary speed limits.

Police have suspended the use of the cameras.
