Under free-flowing traffic conditions, there is no such thing as the &quot;fast lane.&quot; What you&#x27;re thinking of is called the &quot;passing lane.&quot; If you are not actively passing someone in the cruising lane, then you need to get out of the passing lane, right now. If someone in the cruising lane is next to you and going the same speed as you, then you need to slow down or speed up, move over, and resume your cruising speed. There is no excuse for cruising in the passing lane.
