Guidance if you have received a warning letter.

I have received a warning letter (also called an advisory notice): what do I need to do?

We have reduced speed limits to 50mph to reduce nitrogen dioxide (NO2) pollution on some roads in Wales.

Our partner, GoSafe, is issuing notices to drivers who drive above 50mph on these roads.

We have issued you a letter to remind you that the air quality speed limits are now being enforced for the road on which you were travelling.  If you break the speed limit again it could lead to prosecution. You don’t need to do anything.

I wasn’t driving

The letter is issued against the vehicle and registered keeper.

If the vehicle breaks the 50mph speed limit again, the registered keeper will receive a Notice of Intended Prosecution (NIP).

The NIP will include a S172 request for driver information which should be completed within 28 days of the date on the notice.

I don’t own the car anymore

You are legally required to let the DVLA know that you are no longer the keeper of the vehicle.

My car was not in the area at the time

Please send your details to the Safety Camera Process Unit. Email: scpu@northwales.police.uk

They will investigate whether an error has occurred and to ensure that a vehicle is not linked to criminal activity e.g. cloned number plate/vehicle.

I drive an electric car, why am I receiving a letter?

You have received a letter because you drove over 50mph along one of the stretches of road that have a 50mph speed limit to lower NO2 pollution.

We acknowledge that low and ultra-low emission vehicles are likely to emit much less/zero NO2, but we need all vehicles to stick to the 50mph speed limit. 

Having a separate speed limit for different vehicles would make the road more dangerous.

Can I have photographic evidence of the offence?

If you would like to obtain the photograph of the offence, please contact the Safety Camera Process Unit. Email: scpu@northwales.police.uk

Please be aware it is the responsibility of the registered keeper to know who was driving the vehicle at the time.

Can I appeal the advisory notice?

No. No action is being taken against you. The letter advises you that action may be taken against you if you break the speed limit again.
