Proposals to simplify motorway speed limits for buses, coaches and heavy goods vehicles (HGVs) were published today by the Department for Transport.

The Department reports that the changes are needed because of differences that have arisen between new vehicles, which are fitted with speed limiters, and older vehicles which are not.  This means that while newer HGVs are limited to 56mph older vehicles are able to drive at up to 70 mph on the motorway.  Similarly, new passenger vehicles with over eight seats are limited to 62.5 mph on the motorway but older vehicles are able to drive at 70 mph.

This can cause confusion for other drivers and creates a disincentive for companies to invest in safer and more fuel efficient vehicles.  In addition, vehicles with speed limiters are not allowed to use the right hand lane of three lane motorways but those without speed limiters currently are.

The proposals put forward in the Department's consultation include:

• Setting a 65 mph limit for all buses, minibuses and coaches with more than eight passenger seats regardless of whether or not they are fitted with a speed limiting device;
• Setting the motorway speed limit at 60 mph for all HGVs over 3.5 tonnes regardless of whether or not they are fitted with a speed limiting device;
• Prohibiting all HGVs between 3.5 and 7.5 tonnes and all buses, minibuses and coaches with more than eight passenger seats from using the right hand lane of motorways with three or more lanes.

The consultation is available by clicking here and closes on 27 April 2010.
