"Driving on the Highway
• Make sure your vehicle operates well and can drive at highway speeds.
• Stay to the right and only use the left lane for passing. On an
expressway with three or more lanes in your direction, use the far
right lane for slower driving, the middle lane for faster driving, and
the far left lane for passing."

No, there aren't any sign.
