Drivers’ Hours: A Traffic Commissioner’s Perspective on Safety, Compliance, and Responsibility

23.3.2026 - | Her Majesty's Revenue and Customs

In commercial road transport, few regulations are as vital to public safety and operational integrity as the rules governing drivers’ hours.

As Traffic Commissioners for Great Britain, our statutory role is to ensure that operators and drivers uphold the highest standards of safety, compliance, and professionalism. Drivers’ hours rules are essential safeguards against fatigue, unfair competition, and risk to life. However, there is no research to support that 4 ½ hours is a safe period to drive. The rules aim to prevent operators competing on the basis of driving for longer but actual driving and rest periods need to be based on an analysis of risk taking account of factors such as the type of driving, time of day and the driver’s health and personal situation.

This blog explores how drivers and operators might approach the drivers’ hours framework, the expectations we place on operators and transport managers, and the consequences of non-compliance. It is written to help operators understand our perspective and to promote a culture of proactive compliance.

Why do we have them?

The drivers’ hours rules exist to:

Fatigue is a silent killer on our roads. Studies show that tiredness can impair driving ability as severely as alcohol. The rules are designed to mitigate this risk by enforcing structured rest and break periods.

Where do the rules come from?

There are several sets of rules that drivers must follow. The domestic drivers’ hours rules in Great Britain (GB), working time rules, Assimilated rules (previously called EU rules) and The European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport (AETR) rules on drivers’ hours, breaks and rest.

Or

Most driving falls under what are known as the EU Rules – now called the Assimilated Rules. If vehicles travel internationally, then AETR regulations apply - and these are almost identical to the EU rules. If your work is exempt EU, then domestic rules apply. There are separate limits on working time.

DVSA has a longer guide to them here.

Where does the Traffic Commissioner fit in?

As Traffic Commissioners, we are responsible for:

We take a proactive approach to regulating the industry, focusing on education, prevention, and proportionate response. Our decisions are guided by statutory documents and case law, and by our commitment to public safety.

What common compliance failures do we see?

Despite guidance, we frequently encounter breaches of drivers’ hours rules. These include:

Failure to Take Breaks

Drivers miscalculate or split breaks incorrectly. For example, taking 20 + 25 minutes instead of the required 15 + 30 minutes.

Exceeding Driving Limits

Poor route planning or pressure to meet delivery deadlines can lead to breaches of daily or fortnightly limits.

Tachograph Misuse

Not downloading data frequently enough

Removing cards mid-shift

Using vehicles without inserting the driver card

Recordkeeping Failures

Missing manual entries – especially for occasional drivers

Lost or damaged printouts

Failure to reconcile discrepancies

Lack of Oversight

Transport managers failing to monitor infringements or take corrective action.

When drivers’ hours breaches are brought up in a public inquiry, it often seems like operators and drivers view these rules as something to try to only pay lip service to in a hope to ‘get ahead’, whereas, fundamentally, they are for protecting everyone.

What do we expect from operators?

We expect a high level of understanding of the rules.

Robust Systems

 

Operators must have written procedures for managing drivers’ hours, including:

Regular Monitoring

Operators should review tachograph data regularly, carrying out risk-assessments then adopting policies that suit their business and investigating any anomalies. Reports must be signed and retained.

Training and Refresher Courses

Drivers must be trained on the rules and receive regular updates. Transport managers should also be competent in interpreting data and managing compliance.

Disciplinary Procedures

Operators must have a clear process for dealing with repeated breaches, including verbal warnings, retraining, and dismissal if necessary.

What happens when it goes wrong, and infringements are noticed?

Regulatory Actions

When breaches occur, we have a range of options:

We do not take action lightly. Our decisions are based on evidence, proportionality, and the likelihood of future compliance.

Our advice

For drivers –

Based on what we see, we would suggest trying the following –

Know which rules apply to your journey - this will differ for HGV and PSV drivers.

For Goods –

You can find the guide at -

Drivers’ hours and tachographs: goods vehicles - Guidance - GOV.UK

For PSV –

A simplified guide for both can be found here. You can use this as a start point.

Use Your Tachograph Properly

One case saw drivers repeatedly fail to record the mandatory breaks, instead continuing journeys without rest. This led to fatigue-related risks and was flagged during a DVSA roadside check.

Another operator got into a great deal of trouble over tachograph records here.

Use Your Tachograph Effectively

One operator instructed drivers to remove tachograph cards mid-shift to avoid recording excess hours. This deliberate falsification resulted in licence revocation and disqualification of the transport manager.

Remember your tachograph is a great tool for you as a driver if you can keep it accurate!

Plan Your Route with Breaks in Mind

Understand Split Breaks and Rest Periods

Prioritise Your Wellbeing

There is at least one operator that has installed fridges in lorries- see what your company can do for you.

Keep Records Clean

Drivers who are engaged in the process rather than trying to ignore it have fewer problems and are an asset to the business.

This operator was found not downloading tachograph data within the required 28-day period, leaving compliance checks incomplete. This systemic failure led to formal warnings and undertakings at inquiry.

Watch Out for Rule Changes

For Operators, transport managers and fleet managers –

Provide regular training

Promote a culture that values safety

Schedule smartly

Use fleet management software

Audit tachograph data

An alarming number of operators don’t look at the data they have recorded. If you’ve got it, use it!

Final Thoughts

Drivers’ hours regulations aren’t just a legal requirement – they are a shared responsibility between drivers and fleet managers. By combining knowledge, planning, and communication, we can create safer roads and healthier working conditions for everyone in the transport industry.
