    • D In the middle of the curve

    B. Before you enter the curve

    Always reduce speed before entering a curve to a speed that lets you apply slight, steady acceleration through it. Braking hard after you are in the curve can cause the tires to lose traction.

  3. What is the best way to avoid hydroplaning?

    • A Brake hard whenever you see a puddle
    • B Turn on cruise control to hold a steady speed
    • C Slow down on wet roads and where water is pooled
    • D Speed up so the tires cut through the water
    Show answer

    C. Slow down on wet roads and where water is pooled

    Hydroplaning happens when the tires ride on a layer of water instead of the road, like water skis. Slow down in the rain and on roads with pooled water to keep your tires in contact with the pavement.

    • B Keep the normal posted speed if no one is crossing
    • C Stop completely before entering the zone
    • D Honk to warn the children as you pass
    Show answer

    A. Obey the lower school zone speed limit

    In a school zone, when lights are flashing or children are present, you must obey a slower speed limit. At a crossing with a traffic patrol, stop and yield if signaled to do so.
