What must you do when entering a divided highway?

Answer: A — You must yield to traffic in the other lanes

When entering a divided highway, it is important to yield to traffic in the other lanes. This is because the other traffic may be traveling at a higher speed and have the right of way. Forgetting to signal or stopping at the stop line are not relevant actions when entering a divided highway. Merging into the other traffic without yielding can be dangerous and may cause accidents. It is important to always yield to other vehicles on the road to ensure safe driving.
