Traffic calming measures

Other traffic calming measures to tackle speeding in your area.

How to request traffic calming for your road

Requests for traffic calming measures to be introduced will reviewed in line with:

  • current county policy
  • consultation with the community
  • consultation with local councillors
  • current funding availability.

You should contact us to make your request.

The County Local Committee is designed to get your opinions heard on many key local issues affecting West Sussex.

30mph repeater signs

The use of speed limit signs is restricted by law. The existence of a system of street lighting in an area indicates that a 30mph speed limit applies (unless signed otherwise) and prohibits the installation of 30mph repeaters. Effectively, the lamp columns act as the repeater signs.

Road humps

On the public highway such measures must be lawfully placed by West Sussex County Council (WSCC) as highway authority, otherwise it is an illegal obstruction.

For a road hump, or any other traffic calming feature, not to be classified an obstruction, it has to be:

  • built in accordance with national regulations
  • undergo the appropriate consultation for a Traffic Regulation Order
  • be approved by the highway authority.

Traffic calming on private roads and streets

Consideration must first be given to whether the public have a right of way along the road. You can find out if a road is a public highway on our highway boundary information page.

You may also need to check with Land Registry with regards to road ownership. If it is public highway, then highway law applies and you must follow the national regulations and guidance on the use of traffic calming.

We would also recommend you seek independent legal and professional engineering advice, especially regarding any liability arising from a traffic calming scheme, whether or not the public have the right of way along the road.

Additionally, it is worth noting that traffic calming schemes can be expensive, especially if street lighting has to be installed or upgraded to reach the standards required by law, as well as any changes to drainage that may be required.
