If you are on a three-lane freeway, treat the right lane as the slower-speed through lane, the middle lane as the higher-speed through lane, and the left lane as the passing lane. Before changing lanes, check your rearview mirrors. Then use your turn signal. Just before you leave the lane,glance quickly over your shoulder to make sure thereisn't another vehicle in your "blind" spot. If you are moving from an outside to center lane ona a freeway having more than two lanes, make sure another vehicle isn't about to move into same spot. Look at the the vehicles two lanes overand watch for telltale signs: turn signals flashing, an increasein speed, or moving toward the edge of the lane. Be prepared to delay your move. Once you are moving on thefreeway, make certain you allow a reasonable following distance.Expect to move slightly slower at night. any circumstances, stop and back up. Drive on to the next exit. At each exitpoint is a deceleration lane. Ideally it should be long enough for you to enter it at freeway speed (after signaling, of course) and then do your braking before moving onto the exit ramp. Unfortunately, not all deceleration lanes are long enough -- some are tooshort for all the braking. Decide when to start braking. If you must brake on the through lane, and if there is traffic close behind you, you can allow a little extra timeand flash your brake lights (inaddition to your turn signal) as extra warning that you are about to slow down and exit. The exit ramp can be curved, sometimes quitesharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distanceat higher speeds, you may tend to think you are going slower than you actually are. For example, 40 mph (65 km/h) might seem like only 20 mph (30 km/h). Obviously, this could lead to serious trouble on a ramp designed for 20 mph (30 km/h)! Leaving the Freeway When you want to leavethe freeway, move to the proper lane well in advance.
