Speed Indicator Devices
Speed Indicator Devices or 'SIDs' are temporary
mobile interactive signs designed to alert passing motorists of
their speed.
Make SID smile!
If the motorist's speed is within the speed limit, SID rewards them
with a smiley face. If it is above the limit, SID displays a
frowning face to remind them that they should slow down. The device
is a non-threatening way of encouraging drivers to observe the
speed limit for the benefit of community safety and quality of
life.
Recent research undertaken by Dorset County
Council has shown that speeds are reduced by an average of
around 5mph at sites where SID is being used.
SIDs are available for use by Parish Councils and recognised
community groups on roads with a speed limit of 40mph or less. To
make a request contact the Highways
Service in writing either, by email entering 'SID Request'
in the subject field, or by letter. Groups other than Parish
Councils should make their application through their local Parish
Council where one exists.
The Highways
Service will advise you whether your application can be
progressed and when to submit a SID Site Request Form.
