Chicago’s taxi regulator, Rosemary Krimbel, the Business Affairs and Consumer Protection commissioner, revealed on Twitter this Sunday that her department is teaming up with the Chicago Department of Transportation to build awareness that people opening car doors need to look out for passing cyclists. Based on a simple reminder — “LOOK” — this city-led anti-dooring effort will join a grassroots campaign launched in early March.

Here’s what Krimbel tweeted two days ago:

@gabe_klein @therealbevin Training includes classes on pedestrian and bike safety. New stickers coming soon for cab windows!

CDOT spokesperson Pete Scales said in an email last Thursday that the “LOOK” stickers are a few weeks away from going public. “They are not yet at the printers, but we’re hoping to get that ordered soon,” he said. “It will be a few more weeks more before we roll it out to the public with a press event with BACP.”
