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.
Auxiliary lanes at intersections and interchanges often help to facilitate traffic movements. Such added lanes are to be as wide as the through-traffic lanes but not less than 10 ft. Where continuous two-way left-turn lanes are provided, a lane width of 10 to 16 ft. provides optimum design. Category: 231 Typical Section Elements for Roadways.
