Drivers of buses, coaches and HGVs could face lower motorway speed limits following proposals by the Department for Transport.
New vehicles are currently fitted with speed limiters, meaning an HGV is only able to drive at up to 56mph on the motorway, while a vehicle with more than eight seats can reach up to 62.5mph.
However, older vehicles that are not fitted with the limiters, can reach speeds of up to 70mph.
This can cause confusion for other drivers and create 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.
The plans put forward by the Department for Transport include setting a 65mph limit for buses, minibuses and coaches travelling on motorways and a 60mph limit for HGVs over 3.5 tonnes.
They also ban HGVs between 3.5 and 7.5 tonnes and buses, minibuses and coaches from using the right hand lane of motorways with three or more lanes.
