You have just left an expressway and are starting to drive on an ordinary highway. You should:

  1. Check your tires for correct pressure
  2. Check your speedometer to keep at the lower speed limit ✓
  3. Stay twice as far behind other cars
  4. Change gradually to the lower speed limit

Answer: B. Check your speedometer to keep at the lower speed limit

Check your speedometer after leaving the expressway so you stay within the lower posted speed limit.

Why this is the answer

The manual says that after you leave an expressway you should look for speed limit signs and check your speedometer to make sure you are within the posted limit. It notes that you are not likely to be on a 55 mph road, so the limit you meet may be lower than the expressway speed. That is why the correct action is to watch your speedometer and obey the lower posted limit, rather than doing the unrelated things listed.

Why the other answers are wrong

Remember it

Expressway exit: look for the sign, then check the speedometer.
