Final answer:
A broken line next to a solid line on a road indicates that traffic on the side of the broken line may pass when safe, while traffic on the side with the solid line may not pass.
Step-by-step explanation:
When it comes to understanding traffic markings, knowing what a broken line next to a solid line indicates is crucial for safe driving. A broken line adjacent to a solid yellow line on a road conveys specific passing rules for traffic. The proper interpretation is that traffic on the side of the broken line may pass when it is safe to do so, while traffic on the side with the solid line is not permitted to pass. Therefore, the correct answer is: 3) Traffic with the broken line may pass while traffic with the solid yellow line may not pass.
This traffic rule is established to manage the flow of vehicles and enhance safety for all road users. It ensures that traffic can proceed smoothly without dangerous passing situations on two-way roads.
