Say cheese
I saw them putting up red light photo enforcement equipment this afternoon at the intersection of NE Broadway and Grand Avenue in Portland. The camera I saw is aimed at traffic on Broadway, which is one way going westbound. I didn't see one pointed at the traffic on Grand (northbound), or anything at nearby Broadway and MLK Boulevard, but I suspect they are soon to follow (if they didn't get there later today).
This equipment makes it easy and cheap for the city to give you a ticket for running the light. Your paying the ticket and your increased auto insurance premiums will be not so easy or cheap.
