How wide is a single lane?

Question

How wide is a single lane?

Answer 1

Half the width of a duel carriage way.  :)

Answer 2

I think the standard lane on an interstate is 12 feet wide.

To whoever said add 4 inches to the width of your car, you are crazy.

Answer 3

In the UK, the standard road width for a road carrying two-way traffic is 8.3 metres.

As a consequence, the standard for a single lane is 4 metres

Answer 4

measure the width of ur car and add about 4 inches to it

Answer 5

In the US, most lanes on an interstate are 10 -12 feet wide and can be as wide as 16 feet in special areas. On other roads, they are as narrow as 8 feet. Private drives, or lanes to rural houses may be no more than 2 ruts the width of the wheels, with the underbrush cut back from them.

Answer 6

12 feet or more is standard, but it is often less due to various constraints
