Driving Environments Posted On April 8, 2015 Tweet Facebook Gmail Linked In If you plan to exit the highway, move to the right lane about 1 mile prior to your exit so that you can reach the exit ramp safely. Communicate with other drivers by using your directional signals to signal a lane change as early as possible. Look for taillights of cars in front of you. If you see illuminated, red taillights ahead, be prepared to slow down or stop.
