Answer :
Final answer:
Drivers entering from the right must yield to traffic on the main route and use speed-change lanes to merge smoothly and safely. Hence option 1 is correct.
Explanation:
When merging with traffic on the main route, drivers entering from the right must yield to traffic on the main route. This means they should give the right of way to vehicles already on the main route. They should not attempt to speed up and merge quickly as it can be unsafe and disrupt the flow of traffic. Drivers entering from the right should also use their turn signal to indicate their intention to merge, ensuring that other drivers are aware of their presence.
