Leaving the Freeway If you are moving from an outside to a center lane on a freeway having more than two lanes, makesure another vehicle isn't about to move into the same spot. Look at the vehicles two lanes over and watch for telltale signs: turn signals flashing, an increase inspeed, or moving toward the edge of the lane. Be prepared to delay your move. Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leavethe freeway, move to the proper lane well in advance. Dashing across lanes at the last minute is dangerous. If you m i s s your exit do not, under any circumstances, stop and back up. Drive on to the next exit. At each exit point is a deceleration lane. Ideally it should be long enough for you to enter itat freeway speed (after signaling, of course) and then do your braking before movingonto the exit ramp. Unfortunately, not all deceleration lanes are long enough-some are too short 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 time and flash yourbrake lights (in addition to yourturn signal) as extra warning that you are about to slow down and exit. The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower thanyou actually are. For example, 40 mph (65 km/h) might seem like only 20 mph (32 W h ) . Obviously, this could lead to serious trouble on a ramp designedfor 20 mph (32 km/h)!
