California cars and bicycles, meet your new three foot buffer zone.

Governor Jerry Brown signed into law on Monday a measure that defines the space required between bicycles and vehicles on public streets. Previous legislation stated that drivers could pass cyclists at a safe, but undefined, distance.

Sponsored by Assembly Member Steven Bradford (D-Gardena), AB 1371 amends the vehicle code to "explicitly define a safe passing distance as a minimum of three feet," according to a news release from Bradford's office.

The announcement distinguishes California as the 22nd state to adopt this type of law, and says AB 1371 will go into effect September 16, 2014.
