If your fleet runs into Greater London, DVS London 2024–2025: Progressive Safe System Installation and Permit Guide is the playbook you need. The rules changed on 28 October 2024: HGVs over 12 tonnes must be 3-star direct vision or be retrofitted with the Progressive Safe System (PSS) to obtain/retain an HGV Safety Permit. Miss it and you risk daily penalties, lost access, and unhappy customers.
Introduction to DVS London 2024–2025
Overview of Direct Vision Standard (DVS)
London’s Direct Vision Standard scores HGV cabs from zero to five stars based on how much a driver can see directly through the windows (without mirrors/cameras). Since 28 October 2024, the minimum to operate is three stars, or you must fit the Progressive Safe System and re-apply for a permit. Enforcement is 24/7 across most of Greater London.
Why the Progressive Safe System (PSS) matters
The PSS is Phase-2 of DVS. It adds tech that detects vulnerable road users (VRUs) at the nearside and directly in front of the cab (where most fatal conflicts occur), plus camera visibility, warnings, and side protection. Zero-, one-, and two-star vehicles must fit PSS to keep operating.
Installation Requirements for Progressive Safe System
Mandatory Components of PSS
TfL’s specification (summarised by the Road Haulage Association) lists seven core requirements. We group them by function:
| Function | What must be fitted | Why it’s there |
| Nearside visibility | Camera Monitoring System (CMS) on the nearside or a CMS that replaces Class V/VI mirrors | Eliminates nearside blind spot and gives a clear in-cab view. |
| Mirror coverage | Class V and VI mirrors (unless replaced by CMS) | Ensures legal mirror coverage where CMS isn’t used. |
| Nearside VRU detection (BSIS) | Blind Spot Information System with full-length nearside coverage on rigids; must avoid false alerts on street furniture | Warns of cyclists/pedestrians on the left; aims to prevent left-turn collisions. |
| Front VRU detection (MOIS) | Moving Off Information System monitoring the frontal “kill zone”; warns at move-off | Addresses the front blind spot at pull-away. |
| Physical protection | Side underrun protection both sides (where practicable) | Barrier against dragging/entrapment. |
| External alerts | Audible warning when turning left (right for LHD) and reversing | Tells VRUs what the HGV is doing. |
| External signage | Clear, legible warning signage (TfL suggests A3 size where possible) | Consistent, easy-to-see warnings for VRUs. |
Important nuance: Systems certified to UNECE R151 (BSIS) and R159 (MOIS) are a good indicator, but PSS detection zones can be stricter (e.g., detection right up to the vehicle side and nose). Aftermarket kits stamped “R151/R159” don’t automatically equal PSS-compliant—check the TfL PSS technical spec or obtain a letter from your supplier.
Installation Process and Timeline (from real fleets)
- Survey each vehicle (tractor + body type) to determine BSIS sensor count/placement, CMS camera positions, power/load on vehicle electrics.
- Quote + plan: agree kit list, lead times, and retrofit timeline planning to minimise downtime.
- Fit & function-test: calibrate BSIS/MOIS zones, set audible warnings, check in-cab monitor view and night glare.
- Capture evidence: take required photos and secure a sensor functionality statement from your installer (details below).
- Apply/renew permit: submit evidence; track your permit application steps and application submission timeline.
Many fleets used third-party installation contractors; TfL does not accredit installers or certify kits—compliance rests with the operator. Build an installation contractors network and keep work order tracking for audit trails.
Obtaining the HGV Safety Permit
Application Process Overview
- Check star rating (VIN-based via manufacturer or TfL checker), then apply online for your HGV Safety Permit.
- The permit is free of charge; approvals are electronic. Fleet tools allow multi-vehicle applications.
Who needs to re-apply?
All vehicles ≤2-star (or unrated) need a new PSS-compliant permit from 28 Oct 2024. Vehicles already 3–5 stars keep their permits to the original end date (some until 2030) and don’t need extra evidence.
Safety Evidence Requirements (what TfL asks for)
For 0–2 star (or unrated) vehicles, submit:
- Two photos: front-nearside and rear-nearside with number plates visible, clearly showing PSS components installed.
- Sensor functionality statement: a letter from the installer or OEM stating BSIS and MOIS are active, “fully functional, effective,” and installed to PSS technical specs. (Third-party certification not required; a signed installer letter is acceptable.)
Pro tips (Safety Evidence & “safety evidence package”)
- Photograph visual inspection criteria: camera heads, nearside radar positions, sideguards, speaker locations, and signage.
- Keep the invoice/worksheet linking VIN ↔ kit serials.
- Store evidence in your fleet compliance program folder with renewal reminders set.
Managing and Renewing Your Permit
- Build a maintenance schedule for sensors, alarms and camera lenses; document emergency equipment checks.
- When vehicles change vehicle dimensions (body rebuilds) or vehicle modification affects detection fields, re-test and re-evidence.
- Use your TMS to flag permit renewal process windows alongside LEZ/insurance renewals.
Grace Period and Compliance Deadlines
What the 2024–2025 Grace Period was
TfL and London Councils agreed a six-month enforcement grace for fleets that applied on time and proved they had PSS booked/ordered. It ran 28 Oct 2024 → 4 May 2025 (23:59). It was not automatic and needed a TfL approval per vehicle (bulk route for >100 vehicles). Note: the application window closed in October 2024; if you didn’t apply, you don’t have grace.
How operators applied (for the record)
- Hold a London Road User Charging (LRUC) account.
- Submit a DVS enquiry with proof (booking confirmation/equipment order) showing installation after 28 Oct 2024 but by 4 May 2025.
- Apply per-vehicle (bulk route open 1–27 Oct 2024 for 100+ vehicles).
If you had grace, it ended 4 May 2025—by then you needed the PSS installed and a live permit on each vehicle.
Penalties for Non-Compliance
Potential Fines and Enforcement
Operate an HGV >12t in Greater London without a valid permit (or in breach of permit conditions) and you face a Penalty Charge Notice (PCN) up to £550 per day, typically reduced to £275 if paid within 14 days. Guidance also notes possible operator £550 and driver £130 PCNs in some circumstances. Non-payment can escalate (e.g., Charge Certificate).
Penalty quick table
| Situation | Typical outcome |
| HGV >12t in DVS zone, no valid permit | PCN up to £550 per day (often £275 if paid in 14 days) |
| Repeat non-compliance | Multiple daily PCNs; possible enforcement escalation |
| Permit breaches (e.g., evidence doesn’t match the truck) | PCN; permit may be revoked/suspended until rectified |
(Always check the latest TfL penalty page for current amounts and processes.)
Strategies to Ensure Compliance (and avoid PCNs)
- Calendarise DVS alongside LEZ and insurance renewals.
- Audit readiness: a quarterly audit of permits vs. VRNs, star ratings, photo evidence dates, and installer letters.
- Driver toolbox talks: how BSIS/MOIS alerts work, avoiding driver distraction, and what to do if a sensor fails mid-route.
- Spare kit plan: carry a spare in-cab monitor and speaker; agree third-party installers for breakdown cover.

Budgeting, procurement, and “how to choose” (practical tips)
- Safety equipment standards: ask vendors to cross-map their kit to TfL’s PSS spec (showing BSIS/MOIS zones). Request drawings of detection fields beside your wheelbase to avoid blind spots at the vehicle size restrictions you operate.
- Retrofit financing options: some providers offer staged payments; otherwise treat as a capex bundle per VIN and amortise against London revenue.
- Grant funding eligibility: limited; check borough-level road safety or air-quality funds and industry bodies for time-bound schemes (not guaranteed).
- Installation requirements: insist on a sign-off sheet and in-cab driver briefing card; add the kit to your maintenance schedule.
- Operator training requirements: brief drivers on alert logic, road safety measures, and how to keep camera lenses clean (especially winter).
Step-by-step: HGV Safety Permit (what the back office actually does)
- Check star rating per VRN; export a list using TfL’s multi-vehicle checker.
- Decide PSS scope: 0–2-star vehicles need PSS; order parts; book installs.
- Collect evidence: two photos per VRN + functionality statement for sensors.
- Apply: submit online; monitor status; save the electronic permit (no need to display).
- Ongoing compliance monitoring: monthly spot-checks that fitted kit still works; capture any inspection requirements results, and track audit readiness.
FAQ (fast answers for planners)
Is the permit free?
Yes—applying is free of charge. Budget for the PSS retrofit, not the permit.
We’re mostly 3-star. Do we need to do anything now?
Keep your existing permits; no fresh PSS evidence is needed unless your rating changes (e.g., after vehicle modification). Some 3–5 star permits run to 2030.
What if our kit meets UNECE R151/R159—are we done?
Not necessarily. PSS detection zones can be tighter; confirm with your supplier and obtain the installer letter for your safety evidence package.
What were the grace-period dates?
Granted cases ran 28 Oct 2024 → 4 May 2025. Applications closed in October 2024; they required proof of booked installs.
How big are the fines?
Typically a £550 PCN (often £275 within 14 days). In some scenarios, a £130 driver PCN may also be issued.
Templates you can copy into your SOPs
Permit evidence email (to installer)
Please provide a letter on headed paper confirming the BSIS/MOIS fitted to VIN [ ] are “fully functional, effective, and installed in compliance with the PSS technical specifications.” Include VRN, serials, and install date.
Driver briefing card (PSS use)
- Check nearside camera view on ignition.
- If MOIS/BSIS alarm triggers, pause and confirm surroundings before manoeuvre.
- Report faults via app; avoid masking sensors with road grime or stickers.
Compliance calendar
- Quarterly: photos updated if major repairs/bodywork done.
- Monthly: quick check of alerts, cameras, speakers, signage.
- Annually: audit a sample of vehicles for full PSS function.
The DVS rating thresholds—at a glance
| DVS Star Rating | Permit status from 28 Oct 2024 |
| 0–2 stars | PSS required + new permit (evidence needed) |
| 3–5 stars | Permit continues to expiry; no PSS retrofit required right now |
The “3-star minimum or PSS” rule is the core of 2024–2025 DVS compliance.
