Final answer:
A yellow, skipped or broken center line on a two-lane, two-way road means that passing is permitted when the way is clear and it is safe to do so. It is a universal traffic signal to guide drivers on passing rules.
Step-by-step explanation:
On a two-lane, two-way road, a yellow, skipped or broken line as the center line indicates that traffic on both sides of the line is traveling in opposite directions, and that passing is allowed for drivers driving in either direction when safe. This type of road marking is important for maintaining order and safety on the road, providing guidance to drivers about whether they may pass other vehicles.
If the yellow center line is broken, it generally means that drivers can cross the line to pass other vehicles, assuming the roadway ahead is clear of traffic and it is safe to do so. Contrastingly, a solid yellow line indicates that passing is not allowed. If there is a combination of a solid and broken line, the side with the broken line may pass while the side with the solid line may not.
In summary, such road markings are universal traffic signals that help to prevent accidents and ensure a smooth flow of traffic. Drivers must always exercise caution and consider the safety of their actions on the road.
