An abnormal load is a vehicle that has any of the following:

1. A weight of more than 44,000 kilograms
2. An axle load of more than 10,000 kilograms for a single non-driving axle and 11,500 Kilograms for a single driving axle
3. A width of more than 2.9 metres
4. A rigid length of more than 18.65 metres

If you are responsible for transporting an abnormal load, you need to follow regulations for notifying the authorities. NMWTRA is responsible for all trunk roads within North and Mid Wales and so you will need to notify us of any proposed abnormal load movement on the NMWTRA Network.
The preferred method for receiving notifications is via ESDAL (Electronic Service Delivery for Abnormal Loads) (

Depending on the load you are moving and your route, you may also need to give advance warning to:
1. The police (North Wales Police or Dyfed Powys Police)
2. Other highway authorities
3. Bridge and structure owners (eg. Network Rail)
