While driving on an automobile road, you see this safety sign. What is the correct way to drive?
💡 Hint
For number signs, the unit and the picture are key: arrows between two cars with 'm' mean distance, while a number alone with no unit inside a circle means speed (Annex 6 Nos. 223 and 224 of the Enforcement Rule). Watch out for options that swap speed and distance.
Answer: ②
Explanation
This sign, with a two-way arrow between two cars and '50m', means keep at least the following distance shown (Enforcement Rule Annex 6, No. 223). It is installed on automobile roads. Speed limit signs show only a number without a unit.
