1998 GMC Suburban Owner's Manual - Page 204

Do not get too close to the vehicle you want to pass while you're awaiting an opportunity. For one thing, following t.oo closely reduces your area of vision, especially if you're following a larger vehicle. Also, you won't have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance. When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and don't get too close. Time your move so you will be increasing speed as the time comes to move into the other lane. If the way is clear to pass, you will have a "running start" that more than makes up for the distance you would lose by dropping back. And if something happens to cause you to cancel your pass, you need only slow down and drop back again and wait for another opportunity. If other cars are lined up to pass a slow vehicle, wait your turn. But take care that someone isn't trying to pass you as you pull out to pass the slow vehicle. Remember to glance over your shoulder and check the blind spot. Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are farenough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. (Remember that if your right outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is.) Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. Don't overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not flashing, it may be slowing down or starting to turn. I f you're being passed, make it easy for the following driver to get ahead of you. Perhaps you can ease a little to the right. 4-12
