Passing target: 20/25 correct (TLA practice target)
Warning, Construction & Information SignsStandalone practice
The yellow warning sign shown indicates a lane change in the road ahead. What should you expect?
Correct answer: The right lane ends and its traffic must merge left.
Why
The right-side lane ends. Drivers in that lane must plan a safe merge and yield as required before moving into the continuing lane. The narrowing outer road boundary is solid; it is not a broken lane divider or a parking instruction.
