March is set to bring significant driving regulation changes that will impact car owners and road users across the UK. From updated fuel reimbursements to fresh number plate rules and new pay-per-mile charges, it’s important to stay informed about what’s coming.
One of the biggest updates involves the introduction of new number plates. Starting March 1, 2026, vehicles will feature the latest “26” identifier as part of the DVLA’s biannual registration plate system. While the plates look similar to previous versions, motorists should be aware that the release of “26” plates may reduce the resale value of cars currently bearing the “75” plates. This presents an opportunity for buyers interested in nearly-new models at lower prices.
Experts are cautioning drivers to check their insurance carefully during this period, especially at a time of heightened dealership sales. Darryl Bowman of Cuvva warns that many motorists underestimate the risks of driving without adequate coverage. Penalties for uninsured driving can include fines, penalty points, or even vehicle seizure, so ensuring insurance compliance is crucial.
Fuel rate reimbursements will also see adjustments. Advisories from HMRC have dropped rates for LPG vehicles: those with engines up to 1,400cc will see a decrease from 11p per mile to 10p, engines between 1,401 and 2,000cc will drop from 13p to 12p per mile, and over 2,000cc engines will reduce from 21p to 19p per mile. Petrol and diesel rates remain unchanged as of April.
March will also mark the deadline for government feedback on the proposed Electric Vehicle Excise Duty (eVED), which is expected to begin in 2028. Under these plans, electric vehicle owners would pay 3p per mile and hybrid users 1.5p per mile, a shift aimed at balancing eco-friendly incentives with road maintenance funding.
Fuel duty increases planned for March 23, 2026, have been postponed. After a five-month extension, the fuel duty cut introduced in 2022 will eventually be reversed in three stages: one penny in September, two pence in December, and another two pence in March 2027.
Learner drivers will also face new restrictions. From March 31, 2026, they will only be permitted two changes to their driving test bookings, down from six. This includes altering the test date, time, centre, or swapping appointments with another learner driver. However, multiple changes can be combined into a single request.
Lastly, MOT testers must complete at least three hours of annual training between April and March each year. The DVSA will suspend testers who fail to pass this mandatory assessment by the end of March, ensuring higher standards for vehicle inspections.
With these changes on the horizon, drivers are encouraged to review their vehicle insurance, monitor fuel cost reimbursements if applicable, and be proactive in adapting to new testing and plate requirements.
