I am thinking mostly of rural roads that are less than the width to
have lanes, to tag these as having two lanes would be wrong and
misleading as, whilst they have a 60 mph speed limit and that speed is
achievable you will expect to have to slow down and take care when
passing other traffic. You also need to slowdown on bends as visibility
is limited.

They are not advisable as through routes for large vehicles.

It is common for other rural roads, whilst mostly 2 lanes to drop in
width where they encounter restrictions, such as bridges. I map the bridge sections with width.
