I would like to know the meaning of the following expression:

Keep left.

Does it mean "maintain on the left-hand-side of a road" or "do not enter"?

  • In countries wherein one drives on the left side of the road, and where tourism is common, "Keep left" reminds tourists from right-side-of-the-road countries that in this country where you are now, drive in the left lane. Aug 10, 2014 at 4:38

To "keep left" means to stay on the left-most lane(s) of the road.

  • Correct. In the United States, it's Keep Right. Or, in Washington State, where I live, it's Keep Right Except To Pass, which means to drive in the righthand lane of two lanes on a 4-lane expressway, normally. The left-hand lane is to be used only for passing slower vehicles. Aug 10, 2014 at 1:44

Stay on your left hand side of the road.


It's context dependent, really.

On a straight two-lane road, the sign would mean STAY IN THE LEFT LANE. However, when you are approaching a divided road, those same words could be used to mean STAY TO THE LEFT SIDE OF THE MEDIAN (or ISLAND), like this:
