Speed and stoppingQuestion 71 of 235

What does the number on a speed limit sign tell you?

  1. The lowest speed that you may drive.
  2. The highest speed allowed when conditions are ideal.
  3. The speed you must keep in all weather.
  4. The speed that is always safe.
Show answer

Correct answer: The highest speed allowed when conditions are ideal.

The number is a maximum, not a target. When the road is wet, dark or busy, a lower speed can be the only legal speed.
