To help vehicles entering the expressway when you are approaching a ramp from the right, you should...

• A. Speed up to merge with traffic.
• B. Move one lane to your left.
• C. Stay in your lane and yield.
• D. Move to the far right lane.

Answer: (B)

When a ramp from the right feeds onto the expressway, merging traffic needs space to slip in safely. The best way to help is to move one lane to the left, if it’s safe to do so, creating a wider gap in the right lane for entering vehicles. Before switching lanes, signal, check mirrors and blind spots, and make sure there’s a safe opportunity to change lanes. This practice reduces the risk of collisions and smooths the flow of merging traffic.

Staying in your lane and yielding without creating space can still force merge vehicles to squeeze in, which is risky. Speeding up to block the merge makes it harder for others to enter. Moving to the far right lane would remove the space you’re supposed to give and can create more merging tension.
