Question 1348 in the bank

Which of the following road signs marks a "freeway"?

Four numbered signs: 217 and 216 blue rectangles with white road and bridge, 217 crossed by black diagonal; 218 blue circle with 55; 219 blue circle with white car.
  1. Sign 218.
  2. Correct answer: Sign 216.
  3. Sign 217.
  4. Sign 219.

Why this is the answer

The correct answer in the official bank: Sign 216.

Sign 216, a blue rectangle showing a white road with a bridge over it, marks the start of a freeway, where special rules apply, such as no stopping and limits on which vehicles may use it. Sign 217 looks almost the same, but its black diagonal line means the freeway ends. A useful rule: a black diagonal stripe across a sign usually marks the end of what that sign imposed.
