A statute is a written law passed by a legislature on the state or federal level.Statutes set forth general propositions of law that courts apply to specific situations. statute begins as a bill proposed or sponsored by a legislator.

The average width of a car lane is 9 feet which is equivalent to  2.7 meters. However, this may vary in some cases like highways  which are 3.7 meters or 12 feet wide.
Cyclists (and indeed motorists) need a bike lane to be between 10ft and 12ft wide. 10-12ft allows motorists to fully merge before a right turn, and it allows cyclists to operate outside the door zone mid-block and with no fear of their vehicle's inherent instability putting them in conflict with other road users.
