What do double yellow lines on the road mean?

  1. You are able to pass other cars

  2. You are able to make a U-turn

  3. Do not cross over the lines

  4. Do not enter the street

The correct answer is: Do not cross over the lines

Double yellow lines on the road indicate a no-passing zone, meaning it is unsafe and illegal to pass other cars. Option A is incorrect because it directly contradicts the meaning of double yellow lines. Option B is incorrect because making a U-turn could result in crossing over the double yellow lines. Option D is incorrect because it does not describe the specific meaning of double yellow lines. It is important to always follow road signs and markings for the safety of yourself and other drivers on the road.
