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.
Although 12 ft. lane widths are desirable on both rural and urban roadways, there are circumstances where more narrow lane widths can be used. In urban areas where pedestrian crossings, right of way, or existing development become stringent controls, the use of 10 or 11 ft. lanes is acceptable.
