Two solid yellow lines indicate no passing. Never drive to the left of these lines unless you are:
In a carpool lane/high occupancy vehicle (HOV) lane that has a designated entrance on the left.
Instructed by construction or other signs to drive on the other side of the road because your side of the road is closed or blocked.
Turning left across a single set of double yellow lines to enter or exit a driveway or private road, or make a U-turn.
