If, hypothetically speaking, there were a war on cars in D.C., the battlefield just got a little trickier for drivers.

The Metropolitan Police Department announced today that it will install automated traffic enforcement cameras throughout the city that will ticket drivers for offenses like not stopping for pedestrians at crosswalks and not stopping at stop signs.

The DC Street Safe campaign targets aggressive driving that endangers pedestrians and cyclists—-and the cameras officially turn on tomorrow. (Only warnings will be issued for the first month or so, with fines starting on Dec. 30)

The cameras will use video analytic and radar technology and will also catch cars speeding through intersections and blocking intersections or crosswalks.

Tickets for failing to yield to a pedestrian or blocking a crosswalk will be $250. Not coming to a complete halt at a stop sign will cost drivers $50. If drivers feels they were ticketed in error, they can contest the fines.

In case drivers are still confused about what’s legal and what’s not, MPD has produced a few goofy, intensely acted videos to explain the program. Watch the rest of the videos, and see where the cameras will be located, right here.
