DVSA Compliance — How to Prepare for Roadside Checks and Operator Inspections

Updated May 2026 — Driver & Vehicle Standards Agency enforcement guidance

DVSA carries out roadside checks on commercial vehicles and separate operator compliance inspections at operating centres. Both types of check have direct consequences for operator licence holders — poor results are reported to the Traffic Commissioner and can trigger a public inquiry. This guide explains what DVSA looks for and how to be prepared.

Roadside checks — what DVSA officers examine

At a roadside check, a DVSA examiner will typically cover:

• Driver documents — driving licence (correct categories), Driver CPC card, digital tachograph card, any specialist certificates (ADR, HIAB) relevant to the load or vehicle
• Tachograph data — the last 28 days of driver activity are downloaded and checked for driver hours compliance, adequate rest periods, and correct use of the tachograph (manual entries, ferry crossings etc.)
• Vehicle condition — brakes, tyres, lights, steering, bodywork; DVSA can issue an immediate prohibition if the vehicle is found to be in a dangerous condition
• Load security — whether the load is properly secured and within axle weight limits
• Operator licence disc — displayed in the cab; confirms the vehicle is authorised under a valid operator licence

Prohibition notices — what they mean

DVSA can issue two types of prohibition:

• Immediate prohibition — the vehicle must stop immediately and cannot move until the defect is remedied. Issued for dangerous defects such as brake failures or a driver without valid documents.
• Delayed prohibition — the vehicle can continue to a specified location (usually the operator's premises or a repair facility) but must be fixed before it returns to normal service.

All prohibitions are recorded on the vehicle and operator licence record. A pattern of prohibitions — particularly immediate prohibitions — is a significant factor in the Traffic Commissioner's assessment of whether an operator is maintaining vehicles properly and managing compliance effectively.

Operator compliance inspections

In addition to roadside checks, DVSA carries out formal operator compliance inspections at operating centres. These are more comprehensive and cover:

• Driver records — hours records, tachograph data, licence and CPC records
• Vehicle maintenance records — inspection schedules, defect reporting, brake testing records
• Operator licence conditions — financial standing evidence, transport manager engagement
• Working time compliance — driver working hours under the Road Transport (Working Time) Regulations

An OCRS (Operator Compliance Risk Score) is assigned to every operator based on enforcement encounter results. A poor OCRS increases the frequency of roadside checks and the likelihood of a formal compliance inspection. A good OCRS reduces scrutiny. The score is calculated from the last three years of encounter history.

The most common compliance failures

Based on DVSA enforcement data, the most frequent issues found at roadside checks:

• Expired or absent Driver CPC cards
• Expired digital tachograph cards
• Driver hours infringements — inadequate rest, excessive driving time
• Vehicle defects — particularly tyre condition, brake performance, lighting
• Tachograph manipulation — the most serious category; can result in criminal prosecution
• Overloading — particularly on tipping and aggregates vehicles

What a compliant operator looks like to DVSA

DVSA's own compliance guidance describes the characteristics of an operator taking compliance seriously. Key indicators include:

• A documented driver document management system — records showing what was checked and when, with expiry dates tracked
• A regular vehicle inspection schedule with records retained
• A genuine transport manager who can demonstrate active involvement
• Driver debrief procedures for tachograph anomalies
• A culture where drivers report defects without fear of pressure to continue
