Weight restriction orders make it an offence to drive a vehicle through the restricted area where the vehicle exceeds the weight limit imposed (unless they're delivering or collecting within the weight restriction).
We have no enforcement powers to deal with vehicles who are not abiding by weight restrictions, this being the responsibility of the police.
If you believe a HGV to be contravening a weight restriction you can report this to the police by calling 101 providing details of date, time, location (road name or number and village), direction of travel and identification of the vehicle (registration number or company name).
The police may not respond directly but will log and review the contravention and contact the haulier or company to confirm if the vehicle was legitimately travelling within the zone or not.
