Two California Highway Patrol officers were among five people injured following a car crash at an anti-vaccination protest in San Francisco. The crash occurred at the San Francisco entrance to the Golden Gate Bridge as protesters gathered for a “nationwide walkout” on Thursday against government-mandated COVID-19 vaccinations.

The two officers and a Golden Gate Bridge employee were hospitalized with injuries not believed to be life-threatening, California Highway Patrol spokesman Andrew Barclay said, reports NBC. Two other bridge employees who were hurt were treated at the scene, he said.

The incident happened in the northbound lane after authorities closed it as protesters threatened to “take over” the road, Barclay said.

The protesters didn’t enter traffic, he said, but the lane remained blocked by a concrete barricade, police officers, patrol cars and trucks.

Aerial video captured by NBC Bay Area shows an SUV and a sweeper truck colliding directly next to the barricade. Both of the vehicles then rammed into a truck that was part of the barricade, thrusting the truck into the two officers and the three bridge employees.

A federal judge earlier this month ruled against California’s 30-foot buffer zone designed to restrict protests at coronavirus vaccination sites as part of a new state law that took effect October 8.

U.S. District Judge Dale Drozd ruled Saturday that the 30-foot limit, which is contained in what he called the law’s “uncommon definition of ‘harassing,’” is too restrictive.

The temporary restraining order bars the state from enforcing the “harassing” portion of the law, while leaving in place the ban on obstructing, injuring, intimidating or interfering.

Those other portions of the law “appear to more precisely target the harms that the Legislature sought to prevent and further the state’s interest in ensuring that Californians can freely access vaccination sites,” he ruled.
