Sample speed limits & control questions
What does the speed on a black-and-white speed limit sign represent?
- A The speed you must drive at all times
- B The minimum speed allowed on the road
- C A suggested speed you may exceed slightly
- D The maximum legal speed in ideal conditions
Show answer
D. The maximum legal speed in ideal conditions
Speed limit signs show the maximum legal speed allowed in ideal conditions. In rain, fog, heavy traffic or darkness, a safe speed may be well below the posted limit.
When should you slow down for a curve?
- A Only if a curve warning sign is posted
- B Before you enter the curve
- C As you come out of the curve
- D In the middle of the curve
Show answer
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.
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.
You are driving through a school zone, the warning lights are flashing and children are present. What must you do?
- A Obey the lower school zone speed limit
- 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.
