Leaving a freeway
There are usually three parts to a freeway exit: a deceleration lane for slowing down that leads drivers out of the main flow of traffic, an exit ramp and an intersection with a stop sign, yield sign or traffic light. When leaving the freeway, signal that you want to move into the deceleration lane, but do not slow down. When you are in the lane, reduce your speed gradually to the speed shown for the exit ramp. Check your speedometer to make sure you are going slowly enough. You may not realize how fast you are going because you are used to the high speed of the freeway. Losing your ability to judge your speed accurately is sometimes called speed adaptation or velocitization. It is a special danger when leaving a freeway. Be prepared to stop at the end of the exit ramp.
Signs telling you that there are freeway exits ahead are far enough in advance for you to make any lane changes safely. If you miss an exit, do not stop or reverse on the freeway. Take the next exit.
