By 1 January 2008, speed limiters will have been fitted to all recently registered, and many older, buses, coaches and goods vehicles over 3.5 tonnes.
All speed limiter settings are specified in kilometres per hour.
For certain classes of vehicle, the maximum speed limit on motorways, as shown in the Highway Code, is now significantly greater than the maximum legal speed permitted by these vehicles’ speed limiters.
This anomaly is acknowledged by VOSA (Vehicle and Operator Services Agency) in their leaflet “New Speed Limiter Legislation” which states:
“It is likely, once all the changes to vehicles requiring road speed limiters have taken place (after 1 January 2008), the national motorway speed limit for goods vehicles over 3.5 tonnes and buses will be lowered.”
Currently, 70 mph is the maximum speed limit on motorways for goods vehicles not exceeding 7.5 tonnes maximum laden weight, and 70 mph is the limit for buses and coaches.
Will these speed limits be brought into line with speed limiter settings? i.e. 90 km/h (56 mph) and 100 km/h (62 mph). Will they be set at 55 mph and 60 mph? Or will they be set at some other values?
When defining speed limits, why not remove the anomalies that arise from using two incompatible systems, and set all national speed limits in kilometres per hour instead?
