What should you do if you enter a highway from an entrance ramp?

Answer: A — Merge into the leftmost lane

When entering a highway from an entrance ramp, you should always merge into the leftmost lane. This allows for a smooth and safe transition onto the highway. Option B is incorrect because stopping and waiting on the entrance ramp can be dangerous for both you and other drivers. Option C is also incorrect because accelerating too quickly can cause you to lose control of your vehicle. Option D is incorrect because it is never safe or acceptable to cut off other vehicles on the highway.
