DVSA Roadside Checks Caught 28,837 Dangerous Cars as Enforcement Fell 9 Percent

DVSA found 28,837 serious roadworthiness defects and traffic offences at the roadside in 2025-26, its own annual report confirms.

The figure sits above DVSA’s official target of 28,000, but it is down from 31,824 the year before, a fall of almost 3,000 cases.

DVSA also brought 829 MOT fraud, dishonesty and negligence cases to court last year, up from 783 the year before.

Fewer Roadside Stops, Same Official Target: What DVSA’s Own Numbers Show

The Driver and Vehicle Standards Agency has published its annual report and accounts for 2025-26, covering the year to 31 March 2026. Buried in the performance tables is a figure that gets little attention next to the agency’s more familiar driving test backlog: how many seriously unsafe vehicles it actually catches on the road.

In 2025-26, DVSA identified 28,837 serious roadworthiness defects and traffic offences through its targeted roadside enforcement work. That is officially a pass. DVSA’s own target for the year was to detect at least 28,000 such cases, and 28,837 clears that bar. But the same report shows the agency found 31,824 cases the year before, in 2024-25. Set the two years side by side and roadside enforcement outcomes fell by 2,987 cases, a drop of more than 9 per cent, while the pass mark itself stayed fixed at 28,000.

A serious roadworthiness defect in DVSA’s terms is not a flat tyre or a cracked wing mirror. It covers faults that make a vehicle a genuine danger on the road: failed brakes, worn steering or suspension components, structural corrosion, or a vehicle that has been altered in a way that makes it unsafe to drive. A traffic offence caught in the same enforcement sweep can include drivers operating without the correct licence, vehicles used commercially without the right operator licence, or drivers’ hours breaches for professional drivers.

Who a badly maintained vehicle on the road actually affects

Every one of the 28,837 cases DVSA caught last year is a vehicle that was, at the point of inspection, unsafe enough for an examiner to act on. Some will have been prohibited from driving on the spot. Others will have led to a fixed penalty or a court referral. The reader who never gets stopped by DVSA still shares a motorway, a roundabout or a school run with vehicles that do not get caught at all, and a falling detection rate raises a fair question: is DVSA finding fewer dangerous vehicles when there are truly fewer of them on the road, or is the same targeted resource now spread across a road network carrying more traffic than it did the year before?

DVSA’s own report does not claim the roads got safer. It frames the fall as part of a shift to a more targeted enforcement model rather than a blanket one, using data from automatic number plate recognition cameras to direct examiners at specific vehicles flagged as high risk before they reach a checkpoint, rather than stopping vehicles at random. In theory that should mean each stop is more likely to find a real defect. In practice, a driver whose vehicle has never attracted attention from an ANPR system has no way of knowing whether that is down to their car being safe, or simply that it has not yet been flagged.

The court figures point the other way. DVSA brought 829 MOT fraud, dishonesty and negligence cases to court in 2025-26, up from 783 the year before, a rise of 46 cases. These are prosecutions against garages and testers who falsified MOT records, issued certificates for vehicles that were never properly tested, or covered up serious faults to keep a car on the road. That side of DVSA’s enforcement work grew even as roadside stops fell, suggesting the agency’s resources moved rather than shrank overall.

How DVSA decides which vehicles to stop

DVSA no longer relies mainly on physically flagging vehicles down at a roadside checkpoint. Its 2025-26 report describes a model built around ANPR data that cross-references a vehicle’s number plate against MOT status, tax records, insurance databases and known risk indicators before an examiner ever approaches it. Remote tachograph downloads can now catch drivers’ hours breaches in commercial vehicles without a physical stop at all, and digital load-check equipment is used to catch overloaded vehicles without them leaving the road.

For an ordinary car driver, the practical effect is that a badly maintained vehicle is more likely to be picked out when it has already triggered a flag somewhere in that system, such as a lapsed MOT or an insurance mismatch, rather than through simply passing an examiner’s checkpoint. A car that has a valid MOT, tax and insurance, but has developed a fault after its last test, is statistically less likely to be the one DVSA’s targeting model puts in front of an examiner.

What drivers should check before DVSA checks for them

A valid MOT certificate is a snapshot of a car’s condition on the day it was tested, not a guarantee that covers the following twelve months. Brake pads wear, tyres lose tread, and suspension components can fail well before the next test is due. Drivers who want to avoid becoming one of next year’s roadside statistics can check tyre tread depth against the legal minimum of 1.6mm, listen for grinding or pulling when braking, and get any dashboard warning light looked at rather than waiting for the next scheduled service.

Anyone who wants to check their own vehicle’s MOT and tax status, in the same way DVSA’s own systems do, can do so free through the government’s vehicle check service on GOV.UK. It takes the number plate and returns the current MOT expiry date, tax status and a history of past advisories and failures going back to 2005, which can flag a recurring fault before it turns into a roadside prohibition.

DVSA’s figures are a reminder that roadworthiness enforcement in Britain now runs largely on data rather than random stops. That is, in theory, a faster way to catch dangerous vehicles. Whether it is catching more of them, or simply fewer of the ones that slip through a data net built on MOT and insurance records rather than a mechanic’s eye, is a question DVSA’s own numbers do not fully answer.

What a prohibition notice actually means for a driver

When a DVSA examiner finds a serious defect at the roadside, the vehicle does not simply get a warning letter. An immediate prohibition notice stops it being driven until the fault is fixed and the vehicle is re-inspected, and for the most dangerous defects that can mean a car is taken off the road on the spot, with the driver left to arrange recovery. A delayed prohibition gives a short window, usually ten days, to get the vehicle repaired before the same rule applies. Both types are recorded against the vehicle and can be checked by anyone using the free government vehicle history tool, which means a prohibition notice can also affect what a car is worth if the owner tries to sell it on later.

Fixed penalties sit alongside prohibitions for less severe offences, and can be issued on the spot for things such as an insecure load, a defective tyre, or driving without the correct licence category. For commercial drivers, a drivers’ hours breach caught through a remote tachograph download can result in a fixed penalty or a referral to a traffic commissioner, who has the power to suspend or curtail an operator’s licence entirely, a much larger financial consequence than a single fine.
