Category B driving licence permitted to drive zero emissions vehicles (ZEV) up to 4,250kg

From today, 10 June 2025, drivers that hold a valid category B driving licence (standard car licence) will be permitted to drive a zero emissions vehicle (ZEV) with a maximum authorised mass (MAM) of 4,250kg.

ZEVs are powered by electric or hydrogen, with the previous permitted limit up to 3,500kg on a standard car license - a limit that still applies for all other vehicle types, including hybrid vehicles.

The DVLA has stated that this change has been implemented to account for the increased mass of batteries and fuel cells in electric vehicles.

The RHA's Head of Technical, Engineering and Policy, Aaron Peters, said: "The increased weight limits allow for the additional weight of batteries and fuel systems in electric and hydrogen-powered vehicles without reducing payload capacity. For operators this can improve operational efficiency and reduce the need for multiple trips."

"Encouraging the use of ZEVs and AFVs aligns with broader environmental goals, reducing emissions and promoting cleaner transportation options within the haulage industry."

This change is only relevant to drivers who passed their test on or after 1 January 1997. Drivers who passed before this date are usually allowed to drive a vehicle and trailer combination up to 8,250kg MAM.
