The sign with a Smile !

Affectionately known as “Smiley SID” Speed Indication Display, SID has gained acceptance by its user selectable “Safety Smile” mode giving a friendly presentation of a serious message, reinforcing safety and educating drivers on site and within our communities.


Covert tool for data capture

The Speed Indication Display provides an extremely effective road safety tool for a range of speed-reduction initiatives; the system provides overt and covert monitoring.

Easy to use

SID is extremely versatile and can be deployed in minutes, coming complete with 10 day interchangable battery and anti-theft bracket, ready to deploy unit.

Powerful features

The Speed Indicator Device (SID) is not just static display. It has several unique features that give users greater flexibility and a better understanding of how to maximise its use as a road safety tool.
