SAN FRANCISCO (CBS SF) — A mass of bicyclists blocked traffic during the first-ever “wiggle stop-in” on the popular bike route in San Francisco’s Lower Haight and Duboce Triangle neighborhoods during the evening commute Wednesday to protest the Police Department’s enforcement of a law requiring cyclists to come to a full stop at stop signs.

The stop-in led to significant traffic delays in the area as cyclists waited their turns at all the stop signs on the route.

Streets that make up the “wiggle” bike path, including Duboce Avenue, Scott Street, Waller Street, Pierce Street and Haight Street, had traffic at a standstill beginning around 5:30 p.m.

The protest was organized by members of the group The Wigg Party who describe themselves as “urban sustainability guerrillas” and said their hope is to change the law to not require cyclists to come to a complete stop.

The group said additional “wiggle stop-in” events might be necessary to get the point across.

The San Francisco Bicycle Coalition is also pushing back against a crackdown by the San Francisco Police Department’s Park Station officers on bicyclists who flout the rules of the road.

The SFPD’s Park Station has stated that their officers will be on the lookout for bicyclists in violation of the rules of the road.

According to the San Francisco Bicycle Coalition, this crackdown is a “significant departure from the SFPD’s Vision Zero Commitment” and argues that the crackdown “risks lives by diverting resources away from the deadliest traffic violations.”

Vision Zero was adopted in San Francisco last year and aims to eliminate all traffic-related fatalities in the city by 2024.

Chris Cassidy, the San Francisco Bicycle Coalition’s communications director, said the crackdown would be at odds with Vision Zero, which is why the bicycle coalition has launched a petition to stop the Park Station from moving forward with it.

Police Chief Greg Suhr said hours prior to the bike-in that stopping at stop signs is still the law in San Francisco and needs to be enforced, but he noted that less than 1 percent ofall citations go to cyclists.

Suhr said just in driving around the city, he has noticed that “there are not a lot of bicyclists who stop really when they’re supposed to stop. And unfortunately, we do have a certain amount of bicyclists get injured as they don’t stop or they go the wrong way.”

Suhr said bicycles are considered vehicles and need to follow the rules of the road.

“I think the bicyclists sometimes are seriously injured or killed and they’re the party most at fault,” Suhr said.

Mayor Ed Lee shared Suhr’s view, expressing support for the Police Department’s decision to enforce the law on cyclists, as well as motorists.

Earlier this week, the department released a statement regarding Park Station’s daily cyclist education and traffic safety enforcement efforts.

“The purpose of this operation is to educate all cyclists as to the inherent dangers of rolling through red lights and stop signs without stopping, as well as yielding the right of way to pedestrians at crosswalks, both of which are mandatory under the California Vehicle Code,” the statement said.

Police said that while other U.S. states have adopted laws that allow cyclists to treat a stop sign as a yield sign, California law still requires cyclists to stop at stop signs.

“However, if new legislation is passed, SFPD will of course enforce the new law. We are required to enforce the laws on the books, and all citizens have a responsibility to keep the roads safe whether on foot, two wheels, or four wheels,” the statement said.
