Those who work on Connecticut’s highways made a passionate pitch Friday for a bill that would allow the use of automated traffic enforcement safety devices within maintenance work zones. The bill would allow cameras to be placed in work zones where there are no police officers on duty starting next January. The cameras will be used to capture the license plate number of any vehicle driving 12 m.p.h. or more over the speed limit in a work zone. Tickets will then be mailed to the registered owner of the vehicle within about 10 days. Any fines collected would be placed in a special “work zone safety account” to be used by the DOT to protect the safety of workers in highway work zones through highway traffic enforcement.
