New Bike Light Shield at Fell & Masonic: Small Change Might Reduce Crashes


With the shield, drivers see the no-turn arrow but not the green bike light to the left

The bike signal lights are obscured from the view of drivers in turning lane

Previously, drivers saw both red and green lights at the same time

Enforcement needed here: some drivers ignore all signals (1pm Nov. 9)

Without fanfare or even an announcement, the San Francisco Municipal Transportation Agency (SFMTA) has installed a shield to the bike light at the intersection of Fell and Masonic. The small adjustment may reduce the risk of collisions for travelers who use the intersection. The shield -- actually metal slits within the housing of the bike light -- obscures motorists' view of the bike signal so they don't think a green bike light allows a left turn from Masonic even with a visible red no-left-turn arrow.

Several collisions occurred at the crossing involving motorists and bicyclists and motorists and pedestrians before the bike light was installed in September 2008, and crashes continued to happen afterwards. Pedestrian and bike advocates have suggested that motorists may get confused by the combination of a red turn arrow and the green light meant only for bicyclists using the crosswalk. They began urging an adjustment within weeks of the initial light installation. Two years later, cyclists noticed the new shield on Monday of this week.*

A stop at the intersection early this afternoon indicated that drivers waiting in the left turn lane were unable to see the bike light. (I asked two motorists waiting for the light since I traveled by bike and did not approach the intersection in a vehicle). However, as happens frequently at the intersection, a truck driver did not see or ignored the red turn signal and nearly hit two cyclists crossing with a green light. As much as the new light shield may reduce collisions, the real solution for safe passage for bicyclists and motorists is to install separated bikeways on Oak and Fell for east-west travel.

Correction: An earlier version of this article listed the date of the bike light installation as January of 2008; the light was installed September 2008.

"I'll Never Do That Again," Bicyclist Tells SFPD After Trying to Beat Signal, Colliding with SUV Driver in NOPA

Trying to beat the light in the North Panhandle is obviously just as risky as many other parts of the city. Yesterday morning a bicyclist spinning southbound in the bike lane down Baker Street from McAllister thought he could clear the intersection at Fulton before the signal changed. Instead, he mis-timed his approach, entered the intersection against the light, and collided with a motorist driving a BMW on Fulton. SFPD and the Fire Department arrived soon after. According to NOPA neighbors Jignesh Desai and Leela Gill who happened on the scene independently after the crash, the cyclist appeared OK even if his bike was badly twisted.

Lt. Mark Solomon, Acting Captain of SFPD Park Station, told BIKE NOPA that the investigation of the collision was straightforward and easier than most. "The bicyclist admitted he was at fault," Solomon explained. "He told us, 'I'll never do that again.'" Solomon said he was uncertain if the cyclist was taken to the hospital. Another officer had already filed the collision report downtown.

In an earlier conversation Solomon said a different bicyclist involved in a collision at Fell and Masonic on September 21 was also found at fault. In that incident a motorist travelling southbound on Masonic entered the intersection at Fell and then stopped before the crosswalk linking the east and west ends of the Panhandle's multi-use path. Pedestrians had already entered the crosswalk with the green light and the right-of-way. Apparently, when the driver noticed a lull, she proceeded to cross the sidewalk. In those few seconds a bicyclist entered the crosswalk with the green bike light and collided with the vehicle.

Two independent witnesses, one of whom was a cyclist, gave statements during the investigation. They both stated that the motorist stopped in the intersection and proceeded when the crosswalk seemed clear. Both asserted that the cyclist was travelling at "high speed," perhaps 15 mph or more on Panhandle Path when he hit the vehicle. Solomon cited the California Vehicle Code (CVC) 21451 (b), for determining the cyclist's fault. He explained that the cyclist (or any "driver") should have yielded to the motorist who was lawfully within the crosswalk. Had the motorist tried to "beat the light" but got stuck in the intersection when pedestrians were already in the crosswalk? Solomon said the CVC considers the driver legally waiting for the crosswalk to clear. "It's looking for the lull that's important," Solomon concluded.

In the earlier report of this September collision, it appeared that the motorist may have been turning left from Fell onto Masonic against the light. The SFPD investigation found that was not the case: the motorist was travelling southbound on Masonic.

In other SFPD Park Station news:
  • Lt. Solomon confirmed that officers continue to ticket motorists for speeding on Masonic Avenue and making illegal left turns onto side streets. "Five days a week officers are out there on motorcycles, the other two days they're in cars."
  • The one-year federal allocation that financed pedestrian sting operations in the city expired September 30th.
  • Solomon will conclude his position as Acting Captain of Park Station on Sunday, October 10th. Captain Dennis O'Leary will take command of Park Station early next week.
