What type of line allows passing from the side of the broken line, but not from the side of the solid line?

The correct answer is related to the markings used on the road to indicate the rules concerning overtaking and lane changing. A broken yellow line alongside a solid yellow line signifies that passing is permitted when driving alongside the broken line, which emphasizes that it is safe to pass in that direction. However, the presence of the solid yellow line indicates that passing is not allowed from the side of the solid line. This marking is commonly used in situations where it's safe to overtake in one direction, while indicating that it's unsafe to do so from the opposite side.

In contrast, double yellow lines prohibit passing altogether from either side, and a solid white line indicates that lane changes are discouraged, usually due to the proximity to intersections or other hazards. A broken white line allows changing lanes freely, which does not pertain to the concept of passing in the same way as the broken and solid yellow line combination does. Each marking serves a distinct purpose in traffic regulation, helping to ensure the safety of all road users.
