D.C.’s police department has officially launched its Street Safe campaign, “aimed at using new photo enforcement technologies to combat aggressive and dangerous driving habits that endanger some of our most vulnerable road users, such as pedestrians, bicyclists, and other vehicle drivers and passengers.” Translation: The city now has more than 130 new traffic cameras and will be giving out more tickets.

The cameras will be activated tomorrow and will issue warnings to vehicles through December 29. Actual tickets will be issued starting December 30. Here’s what they’ll do:

Gridlock enforcement units that will improve traffic flow by targeting “blocking the box” at intersections;

Portable stop sign enforcement units to reduce violations in residential neighborhoods ;

Portable crosswalk enforcement units that will enhance pedestrian safety at crosswalks near schools, parks, and recreation centers;

Speed enforcement units that will focus on intersections with known speeding problems;

Units that will enforce rules on oversized and overweight commercial vehicles in order to reduce infrastructure damage and enhance quality of life in our neighborhoods.

Locations of the new cameras looking for gridlock, crosswalk, intersection speed, and oversized vehicle violations can be found on Street Safe’s website. A release says the spots “were selected based on a variety of criteria, including sites with crashes and injuries, calls for service, high speed volume, near schools, or in zones prohibited for use by certain commercial vehicles.”

To kick off the campaign, MPD also released a series of light-hearted videos that explain what violations the new traffic cameras are looking for. One of the ads states that, while it’s not possible to fine someone for “being the wrong size for your clothes,” it is possible to fine drivers of oversized vehicles. Fat-shaming and public safety!

Correction: This post originally misreported that the locations of the cameras weren’t available. It has been updated to correct that.
