A. Downshift as you come out of the curve
B. Downshift while in the curve
C. Downshift before entering the curve and accelerate slightly as you go through it
D. Downshift at any time, it doesn't make a difference

3 / 50
A. Both of these answers are correct.
B. You can avoid a head-on collision.

4 / 50
A. Drive alongside other drivers

C. Apply more braking pressure to the brake pedal
Do the following to correct a drive-wheel braking skid: stop braking letting the rear wheels roll again and keep the rear wheels from sliding; counter-steer as a vehicle turns back on course, it tends to keep on turning.
