The roads are changing, and so are the rules. From October 2024, HGVs over 12 tonnes must comply with revised DVS standards to operate in Greater London. For lower-rated vehicles, that means installing a DVS Progressive Safe System and securing a safety permit.
But being compliant on paper isn’t enough. Enforcement officers may conduct a DVS audit to check whether your HGV vehicles actually meet the DVS standards. These compliance checks verify that the correct equipment is installed and working properly and flag any aspects of the installation that may cause issues or fall short of the regulations. These can happen at roadside inspections or follow-up checks, so HGV operators must be prepared.
This guide explains step by step how to prepare for a DVS audit so you can keep your fleet compliant, safe, and on the road.
What is a DVS?
The Direct Vision Standard, or DVS, is a Transport for London (TfL) safety initiative introduced as part of Mayor Sadiq Khan’s Vision Zero for London strategy. This ambitious plan aims to eliminate all deaths and serious injuries on London’s transport network by 2041.
The DVS focuses on reducing accidents involving HGVs, pedestrians, and cyclists and aims to improve visibility from the cab of heavy goods vehicles. Each HGV is assigned a DVS rating from 0 to 5 stars, based on how much a driver can see directly through the cab windows without relying on mirrors or cameras.
Since October 2024, the DVS system has allowed only HGVs rated three stars or higher to operate in Greater London without modification. Vehicles rated 0–2 stars must be fitted with a DVS Progressive Safe System to qualify for a safety permit. The system is designed to address blind spots and improve safety for pedestrians, cyclists, and other road users.
Step 1: Check Your Vehicle’s DVS Star Rating
Begin by checking the star rating of each HGV in your fleet. You can do this through TfL’s official vehicle checker. If your vehicle is already rated 3, 4, or 5 stars, you can move straight to applying for the safety permit.
However, if the vehicle is rated 0–2 stars or has no rating, you’ll need to install a compliant DVS progressive safe system before applying. Keep in mind that the manufacturer determines DVS ratings and relates only to the vehicle’s direct vision, not to any added technology.
Step 2: Fit a DVS Progressive Safe System
For vehicles below the required star rating, the next step is to install a full DVS progressive safe system. This includes:
- A camera monitoring system (CMS) to eliminate nearside blind spots.
- A blind spot information system (BSIS) to warn drivers of pedestrians and cyclists when turning left.
- A moving-off information system (MOIS) to alert the driver to anyone directly in front of the cab.
The system must also include audible warnings when turning, warning signage, and side under-run protection (unless exempt).
To ensure your installation passes a DVS audit, always use an approved supplier familiar with TfL requirements.
This is where Crystal Ball can help. Our Direct Vision Standard Kit London Progressive Safe System (PSS)solution includes all required hardware—DVS cameras, MOIS, nearside sensors, signage and audible alerts—installed to the latest standards.
Step 3: Gather Evidence for Your Permit Application
Before applying for a safety permit, make sure you have the right documentation. This includes two photographs clearly showing the front and rear nearside of the vehicle, with visible registration plates and fitted safety equipment. You’ll also need your installer’s signed Sensor Functionality Statement confirming the equipment works properly and meets DVS standards.
These documents are required for the permit application and will be valuable during any future DVS audit.
Step 4: Submit the Application Online
Once your vehicle is equipped and your evidence is ready, apply for a DVS safety permit through the official TfL portal.
The application is free and typically takes around 10 working days. Permits are valid until 28 October 2030 unless the vehicle is sold. Make sure the vehicle’s details match the submitted documentation or the application may be rejected.
Step 5: Maintain Equipment and Keep Records Audit-Ready
Once your permit is approved, your work doesn’t end there. TfL carries out DVS audits through roadside inspections and camera monitoring, so you’ll need to ensure your equipment always functions correctly. That includes your DVS camera system, monitors, sensors, and audible alerts.
Keeping accurate records, such as installation certificates, maintenance logs, and photographic evidence, ensures you’re prepared if asked to verify compliance. With enforcement penalties of £550 per vehicle per day, even a single lapse can quickly get expensive.
Step 6: Train Your Drivers on DVS Equipment
Your DVS system is only effective if your drivers know how to use it. They need to understand how to interpret alerts from the moving-off information system, monitor blind spots using the DVS camera system, and respond to proximity sensors correctly. Even with the right equipment fitted, a lack of familiarity can lead to incidents or audit issues.
Stay DVS Audit-Ready and Compliant
Preparing for a DVS audit is all about making sure your vehicles are fitted with the right systems, your records are in order, and your team understands how to use the equipment properly. With the right preparation, passing a DVS audit becomes a routine part of managing a safe, compliant fleet.
