New roadside-enforcement data gives van operators a useful reminder: simple defects can stop a working vehicle in its tracks.
The Driver and Vehicle Standards Agency data updated on 17 September 2026 records 1,258 mechanical checks on GB-registered light goods vehicles between April and June 2026. Officers issued 890 mechanical prohibitions, a rate of 70.75%. They also conducted 1,080 weight checks and issued 742 overload prohibitions, a rate of 68.70%.
Those percentages must be interpreted correctly. DVSA roadside activity is targeted, not a random survey of every van on British roads. The figures do not mean that seven in ten UK vans are mechanically defective or overloaded. They show what officers found among the vehicles they selected for closer inspection.
For a farmer, contractor, tradesperson or fleet manager, the commercial lesson is still clear. A roadside defect can interrupt the day, delay customers and generate repair, recovery or enforcement costs.
What inspectors are finding
Tyres were the most frequently recorded prohibition defect. In DVSA’s latest LGV defect table, tyre condition defects were recorded against 22.68% of the vans inspected.
Direction indicators followed at 15.83%, while security of the body was recorded at 10.06%. Other leading categories included exhaust emissions, brake warning systems, seat belts and supplementary restraint systems, parking-brake operation, electrical equipment, suspension springs, and wheels and hubs.
One vehicle may have more than one defect, so the percentages should not be added together. Treat them as a priority list for checks and maintenance.
A practical van roadworthiness routine
1. Start with tyres and wheels
Check every tyre before the first journey, including the inner sidewalls where they can be seen safely. Look for cuts, bulges, exposed cords, embedded objects, uneven wear and incorrect inflation. Confirm that tread depth is legal across the required area and that wheel nuts or indicators show no sign of movement.
Use the manufacturer’s pressures for the vehicle and its load. Uneven wear can indicate an alignment, suspension or loading problem that needs investigation.
2. Test lights with a repeatable sequence
Indicators ranked second in DVSA’s defect table. Make lighting checks a fixed sequence rather than a quick glance.
Test dipped and main-beam headlamps, sidelights, indicators, hazard lights, rear lamps, brake lights, reversing lights and registration-plate illumination. Check that lenses are present, clean, secure and the correct colour.
Where a driver cannot see a lamp from the controls, use a colleague, a safe reflection or another reliable method. A dashboard bulb warning should trigger an inspection.
3. Check the body, doors and load area
Security of the body was the third most common defect category in the latest table. Inspect doors, hinges, shutters, tail lifts, steps, panels, racks and load-area fittings. Nothing should be loose, damaged or capable of opening or detaching on the road.
Secure tools, materials and loose equipment so they cannot move during braking or cornering. Keep the bulkhead and any load-restraint points in sound condition. A tidy load area also makes damage and leaks easier to spot.
4. Know the van’s real operating weight
Payload is not simply the weight of the goods on the delivery note. The vehicle’s gross weight includes the van, driver, passengers, fuel, tools, racking, accessories and load. Individual axle limits matter as well as the overall limit.
Record the plated limits and weigh a representative loaded vehicle at a suitable weighbridge. For changing loads, create simple rules and leave margin for people, fuel and equipment. After deliveries, check that the remaining weight is not distributed poorly across the axles.
5. Inspect the driver’s area
The DVSA van walkaround guidance includes the view through the windscreen, mirrors and cameras, warning lamps, steering, horn, brakes, seats and seat belts.
Clear rubbish and loose objects from the footwell. The driver’s seat must be secure, and the belt should latch, retract and remain free from cuts, fraying or damage. Check that mirrors and camera lenses are clean and correctly positioned.
Any cab accessory must suit the actual vehicle and seat. It must not obstruct a seat belt, airbag, adjustment control, sensor, heating or ventilation feature. Farm Packs supplies heavy-duty van seat covers for working interiors, but fit should always be checked against the real seat configuration before use.
Seat protection can help with routine cleanliness. It cannot make a damaged seat, belt or restraint system safe.
6. Record defects and close the loop
Give drivers a clear method for recording the vehicle, date, mileage, defect and supporting photograph. State who reviews reports, who decides whether a van is safe to move and how the repair is confirmed.
Safety-critical faults should not wait for the next service or MOT. If a driver is unsure, a competent person should assess the vehicle before it returns to service.
7. Audit the routine, not just the paperwork
Managers should occasionally observe the check. If every form is completed in exactly one minute, or repeated defects appear without repair evidence, the process may exist only on paper.
Review patterns by vehicle and defect type. Repeated tyre wear, warning lights or broken load restraints may indicate a wider maintenance, loading or training problem.
The GOV.UK roadside-check guidance explains that police and DVSA officers can stop vans, inspect roadworthiness and authorised weights, and issue a prohibition that prevents further driving until the problem is fixed. The annual MOT does not remove the responsibility to keep the vehicle roadworthy between tests.
A five-minute briefing for tomorrow morning
Before the next shift, ask every van driver to confirm that they will:
- Check tyres, wheels, lights, bodywork and visible leaks before departure.
- Keep the windscreen, mirrors, cameras, controls and footwell clear.
- Inspect the seat, belt and dashboard warning lamps.
- Know the vehicle and axle limits, including people, fuel, tools and accessories.
- Report defects immediately and wait for a clear decision before driving.
DVSA’s latest figures are not a verdict on every van in Britain. They are a useful picture of what targeted enforcement continues to uncover: basic defects and excess weight that can be found before a journey.
The practical response is not a longer form. It is a short, consistent check, an honest loading calculation and a repair process that closes every safety-critical defect before the van goes back to work.
