Older articles sometimes refer to VOSA, but the enforcement body today is the Driver and Vehicle Standards Agency (DVSA). VOSA closed and was replaced by DVSA. [1]
The practical message for van drivers hasn’t changed: if your vehicle isn’t roadworthy, it can fail its MOT — and it can also be stopped at a DVSA roadside check.
Are van MOT failure rates really “50%”?
A blanket “50% failure rate” claim doesn’t match current published DVSA data. DVSA’s MOT dataset shows that class 7 vehicles (goods vehicles between 3,000 and 3,500kg) had an initial fail rate of about 34–35% in the most recent published figures. [2]
Class 4 MOT results cover “cars, vans and passenger vehicles” as a combined group, so they’re not a clean “van-only” measure. [3]
What vans fail on most often (based on DVSA defect data)
DVSA publishes breakdowns of initial failures by defect category. For class 7, higher shares of initial failures include suspension, visibility, steering, and tyres in recent quarters. [4] For the combined class 3 and 4 group (cars and vans under 3,000kg), common failure categories also include suspension, tyres, and visibility. [5] Many failures are linked to wear-and-tear items that can often be spotted early with basic checks.
What happens at a DVSA roadside check?
DVSA officers (and police) can stop commercial vehicles and assess roadworthiness. If a defect is serious, you may receive a prohibition notice, which can prevent the vehicle being driven until the defect is fixed. [6] DVSA sets out how it approaches enforcement and sanctions across road traffic and construction-and-use offences. Serious offences can lead to prosecution and court outcomes, depending on the circumstances. [7]
Buying a used van: what to check with MOT risk in mind
MOT failure rates don’t prove that “half of used vans are poorly maintained”, but they underline why checks matter. Before buying:
- Review the van’s MOT history and look for repeated advisories (tyres, brakes, corrosion, suspension)
- Check tyres for tread and uneven wear
- Look for warning lights on the dash and test all lights
- Inspect windscreen wipers, washers and visibility-related items
- If in doubt, get an independent inspection
Simple maintenance habits that help
A realistic routine for working vans:
- Weekly: tyres (pressure/tread), all lights, windscreen washer fluid
- Monthly: wiper condition, visible leaks, obvious suspension/steering knocks
- Before long jobs: brake feel, load security, mirrors and visibility
Good maintenance won’t guarantee a pass, but it reduces avoidable fails and helps keep the van safer day to day.
