Double-Fine Zones: Do They Work?

State Highway Routes 1 (19th Ave.) and 101 (Van Ness Ave. and Lombard St.) in San Francisco were the targets of Senator Yee's legislation in 2008. In this op-ed, he describes the contrasting results of the double fine on both roads. However, an earlier Examiner article gives a contrasting viewpoint.

"In 2008, after five years of hard work, we were finally able to get a double-fine zone on 19th Avenue when Gov. Arnold Schwarzenegger signed SB 1419 - a bill I crafted with the help of several San Francisco community members. The combination of the fines and the improvements resulted in a substantial drop in traffic accidents along 19th Avenue, and there was not a single pedestrian death in 2009 - a result of which all San Franciscans can be proud."

As part of the compromise to get the double-fine zone on 19th Avenue approved, the Senate Transportation Committee insisted that we also include a double-fine zone on Van Ness Avenue, another dangerous corridor in our city. However, thus far, the (street) improvements that have been made on 19th Avenue have failed to materialize on Van Ness Avenue, and as a result we have not seen a similar statistical change."

From SF Examiner, Jan 13, 2010: Doubled fines fail to deter crashes: "Doubling the traffic fines on city streets that also serve as highways does not prevent car crashes and pedestrian accidents on the busy thoroughfares, according to new statistics. One year into the five-year trial period, however, accidents on one stretch of the roadway covered by the fines have increased by 40 percent, pointing to the ineffectiveness of the penalties alone to make the streets safer for cars and pedestrians."

However, the above collisions were reported on Van Ness Ave (and Lombard St., also part of Hwy 101), not 19th Ave, which saw a decrease in reported collisions.
