Update: Sept. 16, 2014 — Twenty-four states and the District of Columbia require that motorists give bicyclists at least 3 feet of clearance when passing.
Gov. Brown vetoed the two previous bills. In 2012, he cited potential liability problems regarding a provision that allowed motorists to pass on a double-yellow line if that were the only way to give a cyclist 3 feet of space.
The only other governor to reject a 3-foot passing bill has been Texas Gov. Rick Perry.
Virginia’s 3-foot passing law became effective on July 1, 2014, and West Virginia’s law went into effect on June 3, 2014.
Ohio currently has a 3-foot passing bill in the legislature. House Bill 145 is currently before the House chamber after passing out of the House Transportation Committee.
In 2011, Pennsylvania enacted a bill that requires a 4-foot gap.
In reporting on the Pennsylvania bill, the York Daily Record succinctly explained its importance:
“The intent of the new law is pretty clear. Recognize bicyclists as part of the transportation mix and follow some basic rules of the road to ensure the safety for all.”
The 24 states with 3-foot (or more) laws are: Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Illinois, Louisiana, Kansas, Maine, Maryland, Minnesota, Mississippi, Nebraska, Nevada, New Hampshire, Oklahoma, Pennsylvania (4 feet), Tennessee, Utah, Virginia, West Virginia and Wisconsin.
Washington DC also requires a 3-foot passing gap.
The state of Washington requires that motorcycles give bicyclists 3 feet of space when passing in the same lane. The requirement was added as an amendment to SB 5263 in 2013, which sought to require motorcyclists to change lanes before passing other motor vehicles, but not when passing bicyclists. The amendment suggested by Washington Bikes is the first 3-foot requirement in the state and advocates consider it a foundation to expanding to all motor vehicles in the future.

At least five recommend 3 feet in driver’s manuals; four require a safe distance without specifications.
Other new additions to list
Nevada became the 19th state with a 3-foot passing law on Saturday, Oct. 1, 2011, after Gov. Bryan Sandoval signed Senate Bill 248 in law on May 19.
Also in 2011, Kansas and Georgia became the 17th and 18th states requiring that motorists give bicyclists at least 3 feet of space when they pass. Those laws went into effect on July 1.
Meanwhile, at least nine cities in Texas have ratified 3-foot passing bill. That follows Texas Gov. Rick Perry’s veto in 2010 of a statewide 3-foot law that had gained legislature approval but faced opposition from special interests.
Montgomery, Ala., also passed a 3-foot passing ordinance for the city in 2012.

Safe distance states
New York has Merrill’s Law, which requires motorists to “keep a safe distance” when passing a bicyclist. Named for Merrill Cassell, 66, who was sideswiped by a bus and killed. Enacted in 2010.
Rhode Island enacted a law in 2010 that requires motorists pass at a safe distance, defined as a distance sufficient to prevent contact if the bicyclist were to fall into the driver’s lane of traffic.
South Carolina enacted a law in 2008 that requires a “safe operating distance” (not 3 feet per se).
Michigan’s motor vehicle code, section 257.636, says the driver of a vehicle overtaking a vehicle proceeding in the same director shall pass as a safe distance to the left of that vehicle. This applies to bicycles, as bikes are considered vehicles when they’re on the road.
Drivers’ manual states

Bills submitted for 2010
Iowa — Senate File 117 Passed by the Senate in 2009, but stalled in the House. A subcommittee is revamping the 3-foot bill to include provisions to protect “vulnerable users” by adding enhanced fines. More at Sioux City Journal.
Maryland — Senate Bill 51 Requires motorists to pass bicycles by “not less than 3 feet;” also makes it illegal to throw an object at a bicyclist. Also, motorists crossing a bike lane to turn must yield the right of way to bicyclists.
Ohio (announced Sept. 28, 2009) Senate Bill 174 requires a motor vehicle overtaking a bicycle to maintain a safe passing distance between the motor vehicle and bicycle of not less than three feet. It eliminates the current requirement for the operator of an overtaken vehicle, including a bicycle, to give way to the right in favor of the overtaking vehicle at the latter’s audible signal.
Virginia — Senate Bill 566 and House Bill 1048 (HB 1048 defeated) requires motorists give bicyclists at least three feet. The bills also outlaw tailgating and create a a new Class 3 misdemeanor of Careless Driving — to counter the difficulty of charging motorists with Reckless Driving when they kill or injure cyclists. More details at Virginia Bicycling Federation and at Richmond Sunlight (SB 566 and HB 1048).
