Why it matters: Local officials hope the cameras reduce speeds at five intersections where lead-footed motorists have a history of endangering pedestrians, cyclists and other drivers.
How it works: The system will only flag vehicles going at least 10 mph over the speed limit, sending a ticket to the vehicle's registered owner.
A driver's first citation will always be a warning — and the system will only issue warnings during the month of October.
Subsequent offenses will cost far less than a regular ticket (starting at $40).
What we're watching: State law allows Minneapolis to place up to 42 cameras, and city officials have already identified 11 "high priority" locations where they'd like to expand the program.
