California’s new “Three Feet for Safety Act” is about to take effect. The law Gov. Jerry Brown signed a year ago requires cars to keep at least 3 feet from cyclists when passing. The version that will take effect does not allow drivers to cross a double-yellow line to pass. If they can’t abide by the new 3-foot rule, they must slow to “a safe and reasonable speed” when passing. Vetoed versions of the bill allowed drivers to cross double-yellow lines to pass bikes at a safe difference.
