If your vehicles over 12 tonnes enter Greater London, the Direct Vision Standard (DVS) applies to you. It rates how much the driver can see directly from the cab, and it requires a valid safety permit for every vehicle before it uses the capital’s roads. Get it wrong and the operator, not just the driver, picks up the penalty.
The DVS is part of the Mayor of London’s Vision Zero plan to eliminate deaths and serious injuries on London’s transport network by 2041. It measures how much a driver can see directly through the cab windows, without relying on mirrors or cameras, and expresses that as a star rating from zero (very limited direct vision) to five (good direct vision).
Two things about the rating matter for fleet planning. First, it is fixed by the vehicle’s design and generally assigned at the point of manufacture. Second, you cannot change it as an operator. A two-star truck stays a two-star truck; what you can change is the safety equipment fitted around it.
Every HGV over 12 tonnes gross vehicle weight needs an HGV safety permit before entering or operating in most of Greater London. The scheme runs 24 hours a day, every day of the year, and applying is free of charge. Whether or not you think your vehicle meets the standard, the permit obligation applies.
The original scheme allowed zero-star vehicles to operate with a 2019 Safe System of mirrors and sensors. That era has ended. Permits issued under the legacy Safe System conditions expired at 23:59 on 27 October 2024, and it is no longer possible to get a permit on those terms.
Since 28 October 2024 the minimum standard is a three-star rating. Vehicles rated three, four or five stars get a permit on their rating alone. Vehicles rated zero, one or two stars must be fitted with the Progressive Safe System (PSS) to qualify. In practice this means a large share of older rigids and tractor units needed retrofit work before they could keep working in London.
The PSS is a package of measures aimed at protecting people walking and cycling. TfL’s guidance sets out seven requirements:
TfL also recommends deactivating or removing legacy 2019 Safe System sensors when the PSS is fitted. Keeping old sensors running alongside new ones is not required for compliance and risks overloading the driver with competing alerts.
Applications are made online through TfL and are free. Start with the vehicle’s star rating. TfL holds ratings for many vehicles, and its online checker will tell you what it has. If TfL cannot match your registration, you will need proof of the rating from the vehicle manufacturer, usually an email confirmation, plus a copy of the V5C log book, or the non-UK equivalent for foreign-registered vehicles.
If you already know a vehicle is rated zero, one or two stars, you can self-certify the rating by uploading a written statement confirming you are self-certifying and stating which rating applies. That shortcut exists because low-rated vehicles need the PSS anyway; nobody self-certifies downwards to avoid equipment.
Two practical traps catch operators out. Permits are not transferable between vehicles or registration marks, so every fleet addition needs its own permit before its first London job. And if you transfer a personalised plate, TfL cancels the permit recorded against the old mark, so the vehicle needs a fresh application under the new one. Owners of newly registered vehicles should start the process as early as possible, even before TfL knows the registration mark.
The scheme is not limited to UK operators. HGVs over 12 tonnes registered outside the UK need a valid permit to operate in Greater London, applied for in the same way, with the vehicle’s national equivalent of the V5C confirming the registration and VIN.
Left-hand drive vehicles must meet the same requirements, mirrored. Cameras and sensors are fitted to account for the blind spot on the right-hand side of the cab, and the audible manoeuvre warning covers right turns.
A small number of vehicles get a full or partial exemption, mainly specialist construction vehicles built for predominantly off-road use, such as telehandlers and mobile cranes, and vehicles with an active 100 percent Showman’s discount. TfL’s operator guidance carries the full list. If your vehicle is not recognised as exempt, or is registered abroad, contact TfL with the V5C and photos of the vehicle rather than assuming the exemption applies.
Operating an HGV in London without a valid permit brings a Penalty Charge Notice to the operator. Beyond the immediate penalty, repeated non-compliance is exactly the kind of conduct that can reach the Traffic Commissioner, because it speaks to whether an operator takes its safety obligations seriously. For a transport manager, DVS permits belong on the same compliance calendar as MOT dates and tachograph calibration: a simple check, done on time, that avoids a completely preventable problem.
The sensible routine is to check the permit status of every vehicle in the fleet against TfL’s online checker, diarise permit applications for incoming vehicles alongside their delivery dates, and keep the manufacturer’s star rating confirmations with the vehicle files.
