Passing target: 20/25 correct (TLA practice target)
Warning, Construction & Information SignsStandalone practice
The warning sign shows a side roadway joining while continuing as a separate lane. What should you expect?
Correct answer: A new lane is added for the entering traffic.
Why
An added-lane warning shows that entering traffic gains its own lane. Continue following the marked lanes and watch other vehicles. A later lane change still needs a signal, checks and a safe gap.
