You Haven't Learned These Yet

1. If there is two lanes going in your direction, the right lane is the travel lane and the left lane is the passing lane. Let's ponder this difficult situation to avoid all confusion. Driving from point A, the location that you started out from; to point B, the location where you want to end up is called traveling; therefore, you should drive in the 'travel lane', which is the right lane as I stated above.
But, along the way you come upon a car in the travel lane that, of course, is traveling too slow. What to do? If you wish to continue with your speed, then you go into the left lane, which is the passing lane, and pass that car. When you safely clear the car you just passed then you're going to continue traveling; so, guess what? You should get into the right lane to continue your traveling.
To sum up: If you're traveling you should be in the travel lane, and if you're passing you should be in the passing lane. On highways with three or more lanes, the extreme left lane is still the passing lane. In many states passing on the right is lawful also on three or more lanes highways.
All good rules have exceptions:
a. If you're more important than all the other drivers on the highway.
b. If you're always oblivious to the traffic around you. OR
c. If you're just plain stupid.
