What is Direct Vision Standard (DVS)?
The Direct Vision Standard measures how much a driver can see directly through an HGV cab and supports London's HGV Safety Permit scheme.
Freight movements in Greater London may be affected by vehicle safety permits, emission standards, charging schemes and route restrictions. These requirements are separate and must be checked individually for the vehicle and planned time of travel.
| Aspect | What to know |
|---|---|
| Core meaning | Greater London requirement |
| Operational use | Applies to HGVs over 12 tonnes |
| Control point | Uses star rating |
| Key caution | Permit may require safety equipment |
How does it work in practice?
The operator checks the vehicle's star rating and fits the required Progressive Safe System where direct-vision performance is insufficient.
The planner verifies registration, vehicle weight, emission standard, permit status and route before accepting a London delivery. Evidence of compliance and any exemption should be available to the operator.
Decisions, exceptions and reference numbers should be recorded in the transport order or relevant system. This creates a clear audit trail of the information available and the actions taken by each party.
Key points to check
- Greater London requirement
- Applies to HGVs over 12 tonnes
- Uses star rating
- Permit may require safety equipment
Always check current contract terms and official guidance as the correct application may vary by vehicle, goods, route, port, customer role or selected customs procedure.
Why does it matter for urgent transport?
A time-critical delivery can still be delayed or penalised if the vehicle lacks the correct London permit or uses a restricted road. Route compliance must be confirmed before collection.
Good preparation prevents a fast vehicle movement from being delayed by missing documents, unsuitable equipment, incorrect classification or denied access at the collection, border or delivery point.
