Inattentiveness can cause you to drift within your travel lane. As you might expect, drifting can get you into trouble. The moment you realize that you have driven off the right side of the road, let up on the gas. Grip the steering wheel tightly. Your decreasing speed and tight grip on the wheel will eventually give you more control. Continue to steer in a straight line. The condition of the shoulder may cause your wheels to want to turn one way or the other. Again, hold the wheel tightly and on a straight course. Lightly hit the brakes until you feel you have regained control. When your path is clear, signal and turn back onto the pavement when it is safe to do so.
