As if your life wasn’t already full of tough choices, now you’re going to have to choose a lane as well. Bugger.

The lane furthest to the left—the fast lane—is referred to as the “Number 1 Lane”. The next one over is called the “Number 2 Lane”, and so forth. Of course, you won’t ever have a need to call them by name unless one of them is late for dinner, but at least now you know in case anyone ever asks.

You should generally drive in the lane that features traffic that is moving at roughly the same speed that you are. You will usually be traveling in the middle lane, or one of the middle lanes if there are more than three. However, if you’re stuck behind Sister Brakes-a-Lot or wish to drive a bit faster, you should move over to the left lane. (Make sure that you still don’t go faster than the posted speed limit; this isn’t some magical lane where normal traffic rules don’t apply, you know.) If you are Sister Brakes-a-Lot, or if you’re going to need to turn off the road soon, use the right lane.

Unless someone is paying you to interlace fabric, don’t be a weaver. Those who weave in and out of traffic like maniacs will end up flipped over on the side of the road sooner or later, or else they will leave a trail of devastation and destruction behind them. While this concept might excite your inner action junkie, we believe that you’re basically a good person at heart and don’t want innocent people to die. Save the weaving for Grand Theft Auto.
