Vehicle Maintenance and MOT
Understand vehicle maintenance standards and MOT requirements for goods vehicles.
Understand how DVSA uses the Operator Compliance Risk Score to target enforcement, what Green, Amber and Red ratings mean for your business, and practical steps to improve your score through better compliance.
DVSA rates your compliance as Green, Amber, or Red based on vehicle and traffic offences. Improve your score by maintaining vehicles, complying with drivers’ hours, and fixing defects promptly. A good score reduces roadside checks and may qualify you for the Earned Recognition scheme.

The Driver and Vehicle Standards Agency (DVSA) uses a risk-based approach to enforcement. Rather than checking every operator equally, DVSA focuses its resources on operators most likely to be non-compliant. The primary tool for this targeting is the Operator Compliance Risk Score (OCRS), which rates every goods vehicle operator based on their enforcement history.
Understanding how OCRS works gives you a significant advantage. Operators who actively manage their compliance can reduce enforcement encounters, lower insurance costs, and protect their commercial reputation.
DVSA enforcement operates through several channels, all feeding into your OCRS:
DVSA examiners conduct roadside checks at fixed sites and mobile locations across Great Britain. Vehicles are selected based on the operator's OCRS rating, visual condition, and random sampling. During a check, the examiner inspects vehicle condition, tachograph records, driver documentation, and load security.
If defects are found, the examiner can issue:
Every roadside encounter is recorded and affects your OCRS, whether the outcome is positive or negative. A clean check improves your score; a prohibition worsens it.
DVSA compliance officers make announced and unannounced visits to operating centres. They inspect vehicle maintenance records, defect reporting systems, safety inspection sheets, and tachograph download records. Poor record keeping or gaps in maintenance evidence can trigger a referral to the Traffic Commissioner.
Your vehicles' annual test pass and failure rates at Authorised Testing Facilities (ATFs) also feed into the OCRS roadworthiness score. A pattern of first-time failures indicates poor maintenance standards.
If you discover your OCRS is Amber or Red, take immediate action:
If your compliance record is consistently strong, consider applying for DVSA's Earned Recognition scheme. Members share real-time compliance data with DVSA through approved systems, and in return receive fewer roadside checks, formal recognition as a trusted operator, and a competitive advantage when tendering for contracts. Earned Recognition demonstrates to customers and insurers that your compliance is independently verified.
