Speed limit changes

Learn how to get a speed limit lowered, raised or extended.

To make a request you will firstly need to contact us.

Your request will be assessed against the West Sussex Speed Limit Policy (see below) and the opinion of the police sought. The assessment will consider:

  • the characteristics of the road, such as its alignment
  • the level of use by vulnerable road users such as pedestrians, cyclists and equestrians
  • the injury collision record
  • the degree of severance caused to a community by the speed of vehicles
  • the existing surrounding limits
  • the cost of necessary works and enforcement.

If it is considered that a change in the speed limit is warranted then a new Traffic Regulation Order has to be made. This involves a statutory legal process that may take up to nine months to complete.

You can see current and previous consultations on speed limit changes in our Traffic Regulation Order section.

If the road in question has a system of street lighting, with no speed limit repeater signs, the road is already subject to 30mph and we are not permitted to erect 30mph repeater signs. The system of street lighting in a built up area should be sufficient evidence of a 30mph limit.
