General Description

SID detects speeding vehicle by Doppler K-band radar to warn motorists that their speed is above the limit and display
their actual speed together. Limit speed is adjustable to alter the speed threshold as conditions change.

·Speeders will slow down up to 80% of the time when alerted by a SID
·Typical speed reductions are 10-20%
·Overall compliance with the posted speed limit will go up by 30-60%
·ELLUMIN SID is particularly effective at getting “super speeders” to slow down
