Driving a Small Car Without a Full Licence in the UK in 2025

Overview of Category B Driving Licence

A category B driving licence authorises driving cars, small vans, and similar vehicles once the holder has passed the required theory and practical tests. Most drivers in the UK hold this licence type.

In 2025, holding a category B licence allows you to drive:

• Cars, SUVs, vans, or small trucks designed for up to 8 passengers (including the driver)
• Vehicles within specified maximum authorised mass (MAM) limits, which vary by fuel type and vehicle modifications

A higher or additional licence is not necessary for driving many standard and zero-emission small cars under these limits.

Vehicle Weight Limits for Category B Licence Holders in 2025

From 10 June 2025, the UK introduced changes to the maximum authorised mass (MAM) limits for category B licence holders, particularly concerning zero-emission vehicles. The main points include:

Zero-Emission Vehicles (Electric and Hydrogen Cars)

• MAM increased from 3,500kg to 4,250kg
• Applies to electric and hydrogen-powered cars, SUVs, vans, and small trucks
• Vehicles may carry up to 8 passengers, including the driver
• MAM encompasses the total weight of the vehicle plus passengers and luggage
• No additional heavy vehicle licence (such as category C1) is required
• Licence holders are automatically entitled to drive within these limits; no reapplication or licence update is necessary
• Examples of vehicles within this limit include some larger electric SUVs such as the Mercedes EQS SUV and Volvo EX90

Petrol, Diesel, and Hybrid Vehicles

• MAM limit remains at 3,500kg
• Driving heavier petrol, diesel, or hybrid vehicles requires a higher category licence

Vehicles with Disabled Passenger Equipment

• For vehicles specially adapted to carry disabled passengers, the MAM limit is 5,000kg
• Additional weight pertains solely to specialist equipment installed for accessibility purposes
• This allowance enables category B licence holders to operate certain heavier adapted electric vehicles

Regulations on Towing for Category B Licence Holders in 2025

Category B licence holders may tow trailers with certain conditions:

• The combined maximum authorised mass of the vehicle plus trailer must not exceed 7,000kg
• For a zero-emission vehicle weighted at 4,250kg MAM, the trailer can weigh up to 2,750kg
• These limits apply to support lawful towing for various purposes without requiring further licences

Considerations for Drivers Licensed Before 1997

Drivers who obtained their licence before January 1997 retain “grandfather rights,” allowing them to drive vehicles up to 7.5 tonnes without holding a category C1 licence. This entitlement was granted based on the licence rules in place at the time of initial licence acquisition.

Licence Updates and Verification

Drivers do not need to apply for new photocard licences, undertake additional tests, or request specific licence changes to benefit from the updated allowances for zero-emission vehicles.

Drivers are encouraged to verify their licence details via official UK government channels to confirm their current entitlements and understand the exact vehicle categories they are authorised to drive.

Types of Vehicles Included in the Updated Rules

The updated allowances apply to a range of zero-emission vehicles, such as:

• Electric cars and SUVs that meet the new 4,250kg MAM limit
• Electric vans and small trucks relevant for various commercial uses
• Electric minibuses carrying up to 8 passengers, or up to 5,000kg MAM if adapted for disabled access
• Hydrogen fuel cell vehicles, subject to the same regulations as electric vehicles

Important Considerations and Restrictions

• The increased MAM limits apply exclusively to zero-emission vehicles (electric and hydrogen-powered)
• Weight limits for petrol, diesel, and hybrid vehicles remain unchanged at 3,500kg MAM
• It is unlawful to drive any vehicle without a valid driving licence or while holding only a provisional licence unless accompanied by a qualified instructor, in accordance with UK driving laws
• Drivers must comply with all applicable UK traffic laws and licensing regulations relating to provisional licences and learner drivers
• Vehicles exceeding the relevant MAM limits require appropriate higher category licences, such as category C1
• Operating heavier vehicles calls for increased attention to vehicle handling and safety considerations

Summary of Driving a Small Car Without a Full Licence in the UK in 2025

Category B driving licence holders may drive many small cars, including larger electric and hydrogen vehicles, under updated UK law without needing a heavy vehicle or commercial vehicle licence. Key points include:

• Zero-emission vehicles up to 4,250kg MAM are permitted on a category B licence
• Petrol, diesel, and hybrid vehicles remain limited to 3,500kg MAM
• No new licence application or additional testing is required to benefit from the updated allowances
• Towing is permitted as long as the combined MAM of vehicle and trailer does not exceed 7,000kg
• Special adaptations for disabled passengers can increase the permitted MAM to 5,000kg

These regulatory adjustments aim to facilitate the transition to zero-emission vehicles for drivers and businesses while maintaining compliance with licensing requirements.
