To help an entering vehicle on a right-hand expressway ramp, you should

• A. Move one lane to the right
• B. Move one lane to the left
• C. Honk and slow down
• D. Speed up and merge behind them

Answer: (B)

When another vehicle is entering from a ramp, you should create space for them by moving one lane to the left. On a right-hand ramp, the entering driver needs room to merge into traffic, and shifting left opens up a gap in the right lane for them to blend in safely. This helps maintain smooth traffic flow and reduces the chance of a sudden stop or a side-swipe.

The other options don’t fit: moving to the right narrows the merge space; honking and slowing down doesn’t help the merging driver; speeding up to merge behind them can create a collision risk. Always check mirrors and blind spots and signal before changing lanes, and only move if it’s safe.
