Direct Vision Standard safety permit requirements revealed

Fresnel lenses won't meet the vision standard required by TfL's Safety Permit Scheme, but the permits themselves will be free of charge, according to new guidance.

The permit scheme, announced last year and part of the Direct Vision Standard (DVS), is designed to recognise efforts made by hauliers in regards fitting camera and sensor systems.

DVS will rate HGVs depending on the level of a driver’s direct vision from a cab. HGVs will be given a rating between ‘zero-star’ (lowest) and ‘five-star’ (highest). Zero-rated vehicles will be banned from 2020, and three-stars will be required to drive on London’s streets by 2024.

However, the permit as proposed would mitigate this, allowing HGVs that are rated zero-star to continue operating in London past 2020 if they have certain safety equipment fitted.

Under the proposals, all HGVs over 12-tonnes operating in Greater London from 26 October 2020 will need to hold a permit. They will be issued from October 2019.

If an HGV meets the DVS requirement a permit will be granted automatically. If it doesn’t then action must be taken to meet TfL’s Safe System.

The Safe System mandates that front and side blind spots are eliminated via a camera system, and that class V and VI mirrors and a sensor system with driver alerts. Left turn audible and ‘prominent’ signage is also required.

As stated, Fresnel lenses are not considered an appropriate means of minimising vehicle blind spots.

Under-run protection is mandatory. There are some exemptions from the Safe System requirements for emergency vehicles, and in specific cases, recovery vehicles.

The Direct Vision Standard has been described as flawed by road transport trade associations who have argued technology would be more effective and affordable.
