Warning, Construction & Information SignsStandalone practice
You are traveling in the right lane and see the warning sign shown. What should you prepare to do?

Correct answer: Find a safe gap, signal, and merge left before your lane ends.
Why
The right lane ends ahead. Check mirrors and the blind spot, signal, and move left when a safe gap is available. Adjust speed to merge safely and obey any work-zone or merge instructions. Do not force another vehicle out of the way or continue along the shoulder.
