Speed and stoppingQuestion 36 of 235

A construction zone has a lower speed limit. When must you obey it?

  1. Only when workers are on site.
  2. Only on weekdays.
  3. Only when machines are moving.
  4. At all times, also when nobody works there.
Show answer

Correct answer: At all times, also when nobody works there.

Bumps, new oil and loose gravel can be present when nobody works. For this reason the limit applies every time.
