Developed to inform drivers and the community of speed behaviour, SID is a rugged, lightweight radar activated Speed Indication Display  that can be used at temporary or permanent locations.


SID provides a non-confrontational warning to drivers, warning them of their speed via an LED display and putting social pressure on them to decrease speed when required.



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.
