Blocked Bike Lanes

Blocked Bike Lanes

Every day SFMTA receives approximately 40 reports of blocked bike lanes on the streets of San Francisco. Some of these are ride share vehicles that have momentarily crossed over a painted white line while others are more aggressive offenders that have egregiously driven over or around a parking protected delineator designed to clearly protect cyclists from traffic.

Whatever the scenario every time a vehicle crosses into a bike lane it forces cyclists to merge into busy city traffic where they are unprotected from fast moving cars and trucks that can crush them in an instant.

Since 1996 31 cyclists have been killed by vehicles on the streets of San Francisco. Tess Rothstein was riding her bike down Howard St. on the morning of Friday, March 9th, 2019 when a parked car threw open its door in front of her forcing her out of the bike lane and into traffic where she was crushed to death by a 2 1/2 ton delivery truck. She was one block away from the beginning of a parking protected bike lane that would have saved her life.

California Vehicle Code 21209 allows vehicles to enter a bike lane for three reasons:

  • To park where parking is permitted
  • To enter or leave the roadway
  • To prepare for a turn within a distance of 200 feet from the intersection

Under no circumstances is it permissible to park a vehicle in a bike lane, doing so obstructs the lane for cyclists forcing them to navigate around the vehicle putting their lives at serious risk.

If you see a vehicle stopped in a bike lane please report it to 311 either by phone or via their app. This map shows those reports in realtime as they come in helping SFMTA respond and clear the bike way as quickly as possible.

Thank you for not blocking the bike lane with your vehicle.
