Weather disruption
Winter weather is causing disruption to services in some parts of the county. Find out what services may be affected in your area.
A Speed Indicator Device (SID) is a temporary vehicle activated illuminated sign used by local communities to display vehicle speeds. SIDs help to raise driver awareness of local speed limits and are proven to reduce traffic speeds at appropriate locations.
Applying for a SID
We support local communities to own and use their own SIDs. SIDs can only be set up at locations approved and assessed by us. We also need to approve the make and model of the SID.
SIDs should not be deployed permanently, but as directed by us as the Highway Authority. Deployment periods are currently for 4 to 6 weeks per site, with a limit of 3 sites per SID.
SID costs
For full costs and details on approved SID models please email us.
