The speed limit is 55 mph. Ahead is a sharp curve on a wet road, and you cannot see where the curve ends. How should you handle your speed?
A approaches a sharp right bend on a wet two-lane road. Trees hide the end of the curve, and a card states that the posted speed limit is 55 mph.
Correct answer: Slow down before the curve to a speed at which you can use light, steady gas through it.
Why
A curve pushes the vehicle toward the outside, and a wet surface gives the tires less grip to resist it. If you brake hard in the curve, you ask the tires to turn and stop at the same time, which can cause a skid. Slow down on the straight road before the curve, then keep light, steady pressure on the gas to keep the vehicle stable. When you cannot see the end of the curve, slow even more so that you can stop for something hidden.
