KENT, Wash. - The City of Kent has added red light cameras to the intersections with the highest collision rates.

Red light cameras went live at the intersections of Central Avenue and Smith Street, Central Avenue and James Street, and Kent Des Moines Road and Pacific Highway (eastbound approach from the west) on Saturday as part of phase one of the city project.

Drivers will be mailed warning citations from July 13 until August 11. Real tickets will be mailed to drivers after the 30-day warning period is over.

Drivers who receive tickets will owe $136.

The warning period for the cameras in phase one was expected to begin on July 1, but Kent police said the starting date was pushed back due to technical difficulties.

Three additional intersections will go live with cameras at Southeast 256th Street and 104th Avenue Southeast, East Valley Highway and South 212th Street, and Southeast 240th Street and 104th Avenue Southeast at a later date. Drivers will be given warning citations during a 30-day period after the cameras are activated.

In a video released by the city, Kent Police Chief Rafael Padilla said the city did a traffic study looking at collision data to determine where the new red light cameras would be placed. The city said it isn't putting in the cameras for the sake of writing extra tickets, but to keeps roads safer.

Padilla said tickets won’t count as moving violations but civil penalties.
