Driving Small Cars Without Full Licence in UK 2026

Category B Driving Licence Overview

A category B driving licence authorises holders to drive vehicles with a maximum authorised mass (MAM) not exceeding 3,500 kilograms (3.5 tonnes). This commonly includes cars, small vans, and some electric and hybrid vehicles. Obtaining a category B licence requires passing both theory and practical driving tests administered by the Driver and Vehicle Standards Agency (DVSA).

Most drivers in the UK hold a category B licence, which forms the basis for legal operation of standard passenger vehicles. The licence also permits driving a trailer with a MAM up to 750 kg, or towing a trailer over 750 kg as long as the combined MAM of vehicle and trailer does not exceed 3,500 kg.

Changes Affecting Category B Licence Holders in 2026

Recent legislative changes affecting the use of category B licences at the start of 2026 include updates to authorised vehicle weights and allowances, particularly concerning zero-emission technologies such as electric and hydrogen-powered cars.

Expanded Authorised Mass (MAM) for Zero-Emission Vehicles

The UK government updated the regulations to recognise the heavier build of many zero-emission cars due to their battery weight. From June 2025 onwards, category B licence holders may drive certain zero-emission vehicles with a MAM up to 4,250 kg without requiring a larger vehicle licence category.

This adjustment aims to reflect the evolving vehicle market, where electric or hydrogen cars can weigh more than traditional petrol or diesel equivalents.

Petrol, Diesel, and Hybrid Vehicles

Standard petrol, diesel, and hybrid vehicles remain subject to the general 3,500 kg MAM limit for category B licence holders. Vehicles above this weight require additional entitlement, such as a category C1 licence.

Towing Regulations for Category B Licences

Under existing rules, drivers with a category B licence may tow:

• Trailers up to 750 kg MAM with no additional restrictions.
• Trailers over 750 kg MAM where the combined weight of car and trailer does not exceed 3,500 kg.

If the combined weight exceeds 3,500 kg, drivers need to have passed an additional practical test to obtain category B+E entitlement.

Drivers Licensed Before 1997

Individuals who obtained their UK full car driving licence before 1 January 1997 retain special allowances known as “grandfather rights.” These rights permit them to drive vehicles and combinations with a MAM up to 7,500 kg and trailers without needing a Category C1 licence, which would normally be required for heavier vehicles.

This concession does not extend to drivers licensed after this date. Verification of licence entitlements can be done via official DVLA channels.

Verification of Licence Categories and Entitlements

Drivers are advised to consult their driving licence to confirm the categories they are entitled to drive. Licence details are available on the photocard and can be checked online through the official UK government vehicle and driver services website. No additional application or fee is needed to benefit from the expanded allowances covering zero-emission vehicles, provided the driver holds a valid category B licence.

Types of Vehicles Covered by Updated Rules

The updated category B licence allowances apply to various zero-emission vehicles, including:

• Electric cars, such as battery electric vehicles (BEVs) with larger batteries contributing to increased vehicle mass.
• Hydrogen fuel cell vehicles, which also have structural weight considerations.

Examples of vehicles fitting within the extended MAM allowance could include certain electric SUVs and larger zero-emission vehicles on the UK market where the MAM is between 3,500 and 4,250 kg.

Important Restrictions and Considerations

While the MAM extension accommodates heavier zero-emission vehicles, several restrictions remain:

• Drivers must adhere to trailer towing limits relating to combined vehicle and trailer weight.
• Larger vehicles or vehicles exceeding category B licence allowances (above 4,250 kg MAM) require specific higher category licences.
• Vehicle usage remains subject to standard UK traffic and safety regulations.

Additional checks such as valid insurance, road tax (Vehicle Excise Duty), and MOT certification continue to apply regardless of vehicle type or licence category.

Typical Costs in United Kingdom (2026)

When considering driving small cars under a category B licence, typical costs in the UK include:

• Basic option: Private used small petrol or diesel cars generally range from £3,000 to £8,000 depending on age, mileage, and condition.

• Standard option: New or nearly new small electric vehicles typically cost between £20,000 and £35,000, subject to brand and battery capacity.

• Premium option: High-end zero-emission vehicles, including luxury electric and hydrogen models, can exceed £40,000, reflecting advanced technology and features.

Costs are influenced by additional factors such as vehicle insurance premiums, charging infrastructure availability for electric vehicles, and ongoing maintenance requirements.

Summary

In 2026, UK category B licence holders can drive a range of small vehicles, including many zero-emission models with increased weight allowances up to 4,250 kg MAM. Standards for petrol, diesel, and hybrid vehicles remain at 3,500 kg. Drivers licensed before 1997 retain additional entitlements for heavier vehicles. Updated rules reflect the evolving vehicle market and technological changes while maintaining existing restrictions on towing and vehicle weight.

Licence holders can verify their entitlements via the DVLA, and need no additional applications to benefit from these allowances. Understanding UK licence categories and vehicle classifications is essential for compliance with current driving regulations.
