Enforcement is what happens when the rules are tested - at the roadside, in a desk based assessment, or ultimately before a Traffic Commissioner.
DVSA can issue graduated fixed penalties, immediate or delayed prohibitions, and build a picture of your compliance through the Operator Compliance Risk Score (OCRS) that decides how often you're stopped.
These guides explain what a roadside check involves, how penalties and prohibitions are graded, how OCRS is calculated and improved, and how repeated infringements escalate towards a Public Inquiry.

Penalties scale with the seriousness of the breach:
• Up to £2,500 (Level 4 on the standard scale) for drivers' hours breaches.
• Unlimited fines for the most serious tachograph offences, such as failing to fit or use a tachograph. (In England and Wales the old £5,000 cap on these was removed in 2015.)
• Up to 2 years' imprisonment for deliberate falsification of records - and considerably more (up to 10 years) where it's prosecuted as fraud or conspiracy.
On top of any fine, serious breaches can lead to vehicle prohibition, referral to the Traffic Commissioner and operator licence action.
A Graduated Fixed Penalty (GFP) is a fixed fine issued at the roadside by DVSA examiners or the police. The amount depends on:
• the severity of the offence;
• the circumstances of the breach; and
• whether it's a first-time or repeat issue.
It's designed to deal with offences efficiently and reduce court cases, while preserving your right to challenge the penalty in court. The penalty bands are set in legislation - the examiner decides which band applies based on what they find, rather than picking a figure at their own discretion.
Common offences that trigger a GFP include:
• overloading;
• defective brakes, steering or tyres;
• failing to download tachograph data on time; and
• failing to carry the required documentation.
A single GFP is capped at £300. Typical roadside levels are:
• minor breach (e.g. tacho not set to UK for the duty period) - £50;
• moderate breach (e.g. rest period violations) - £100–£200; and
• serious breach - up to the £300 maximum.
Importantly, penalties can stack-up. An examiner can issue up to five drivers' hours penalties in a single check (up to £1,500). The most serious breaches - such as falsifying records - usually go beyond a fixed penalty altogether, leading to prosecution, vehicle prohibition or immobilisation, operator licence action and, in the worst cases, a custodial sentence.
You must be able to show:
• driver’s licence, driver qualification card and digital tachograph card;
• records of driving, other work, availability (POA), breaks and rest;
• manual entries covering out-of-scope work, annual leave and sick leave;
• physical charts and printouts; and
• the current day's records, plus the relevant number of previous days (see below).
How many previous days you need depends on the journey:
• 28 calendar days - for domestic (UK-only) journeys under the assimilated rules, and for AETR journeys to, from or through non-EU countries;
• 56 calendar days - for vehicles and combinations over 3.5 tonnes on international journeys to and from the EU.
NOTE: From 1st July 2026 this also extends to vehicles and combinations between 2.5 and 3.5 tonnes undertaking international hire or reward journeys to and from the EU. Some exemptions apply, see the ‘Exemptions’ article in the ‘Knowledge Hub’, and verify against current regulatory sources before relying on one.
Failure to produce these records is treated as non-compliance with Article 36 of assimilated Regulation (EU) 165/2014 and an offence under Section 99 of the Transport Act 1968, and will trigger enforcement.
