Final answer:
You must slow down or stop for yield lines on the road to let other road users go first, only proceeding when it is safe to do so.
Step-by-step explanation:
When you approach a set of "yield lines" on the road, you must be prepared to slow down or stop if necessary to let any other road users go first. These lines are usually found where a road user needs to be aware of potentially yielding the right-of-way to others, often at a roundabout or a crosswalk.
In the context of driving regulations, yield lines are treated as a sign to proceed with caution. That means you do not have to come to a complete stop unless the traffic or pedestrian crossing conditions require it. If the way is clear and it's safe to proceed, you may continue driving without stopping. However, if other vehicles or pedestrians are present, you must let them go ahead of you.
Remember to always follow the traffic laws and use judgement to ensure safety. The key is to not expect the right of way, but instead be prepared to yield it to others.
