When drivers illegally stop in a bike lane, people on bikes have to ride into traffic to get around the obstacle. It’s annoying, but even worse it can put them in danger when they merge into oncoming traffic. The Arlington Police Department tweeted this handy infographic to help drivers understand if they can stop in a bike lane.

The First Street NE protected bikeway might be a good spot to post the infographic, as people have reported trucks parking there despite the protective barrier.

In the past, the District’s Metropolitan Police Department sent tweets reminding cyclists to wear a helmet or telling drivers to “move to the right” for an ambulance.

MPD has also been more recently tweeting advice including one reminding drivers not to park in bike lanes.

Arlington County has been very successful in promoting cycling but also in educating all road users about how to share the road. Obviously, there’s still a lot of learning to do, but every little bit helps.
