LEZs are designated areas within city roads that limit the entry of vehicles failing to meet specific environmental standards. The initiative targets air quality improvement and public health protection, making cities more livable and attractive for residents, workers, and visitors. Non-compliant vehicles entering these zones will incur Penalty Charge Notices (PCNs).
In Glasgow, the LEZ has applied to buses since 2018. For other types of vehicle, enforcement began on 1 June 2023 (for residents within the zone, enforcement began on 1 June 2024), but Dundee began enforcement on 30 May 2024, with Aberdeen and Edinburgh following from 1 June 2024.
Local authorities determined the geographic scope, scope, and timescales for LEZ implementation.
LEZs operate 24/7 throughout the year, including public holidays. They are monitored using Automatic Number Plate Recognition (ANPR) cameras linked to vehicle licensing databases, identifying non-compliant vehicles. Stationary vehicles are not subject to LEZ restrictions.
To drive within these Scottish LEZ, vehicles must meet the following Euro emission standards:
- Euro 4: Petrol cars and vans
- Euro 6: Diesel cars and vans
- Euro VI: Buses, coaches, and HGVs
Motorbikes and mopeds are currently exempt from LEZ restrictions.
A Vehicle Checker tool is available to verify compliance status.
Fines for non-compliant vehicles
Non-compliant vehicles detected in a LEZ will receive a Penalty Charge Notice (PCN) issued to the registered keeper.
The initial penalty is £60, reduced by 50% if paid within 14 days. The penalty amount doubles with each subsequent breach within the same LEZ, capped at £480 for cars and light goods vehicles, and £960 for minibuses, buses, coaches, and HGVs.
After 90 days without further violations, the penalty resets to £60.
PCNs will include information on payment and appeals. Non-payment within 14 days results in the full penalty rate. Legal enforcement issues in Glasgow from June to October 2023 have been resolved, ensuring current fines are enforceable.
Fined motorists can appeal to the issuing council. If denied, they may escalate the appeal to the Transport Appeal Tribunal for Scotland, and subsequently to the Scotland first-tier and Upper-tier tribunals if necessary.
Foreign vehicles
Non-UK registered vehicles must comply with LEZ standards. Drivers should confirm compliance with their national vehicle authorities before travel.
