Meet the minimum DVS star rating

A vehicle can have a rating of zero stars (the lowest rating, with poor direct vision) up to five stars (the highest rating with excellent direct vision).

When your HGV is rated one to five stars, you can apply for a permit without the need to provide any additional evidence.

Alternatively, if your HGV is rated zero stars, you will need to make your vehicle safer by fitting it with Safe System improvements.

Safe System Measures: Improving HGV Safety

To apply for a permit as a zero star rated vehicle, you will need to fit your vehicle with all the safety equipment listed below to improve indirect vision and help drivers see near the vehicle.                                                                                                                                                                               • Class V and VI mirrors                                                                                                                                                                                                                                     • A fully operational camera monitoring system
