Speed Indication Displays are a proven method of reducing vehicle speeds. CA Traffic's ‘Smiley SID' is simple to use and extremely effective.
The units are no-confrontational and serve as an aid to calming road traffic. Features of the sign include a ‘smiley face’ that rewards drivers for complying with the speed limit and a ‘sad face’ for those which are not.
The SID has two mounting options, making it the most versatile portable speed sign on the market today.
The SID comes in two versions. ‘Simple SID’ is operated by a rotary switch and can be used by the most novice user. ‘Clever’ SID is programmable using the supplied Palm Vx and is capable of recording speeds of up to 250,000 vehicles.
