You may cross double solid yellow lines:
- To pass a slow-moving truck.
- To turn into a driveway. ✓
- To pass another car.
- Under no conditions.
Answer: B. To turn into a driveway.
You may cross double solid yellow lines to turn into a driveway.
Why this is the answer
The manual says double solid lines mean you cannot pass or change lanes. It also says you cannot cross them except to turn left to enter or leave the highway, such as to or from a driveway. That makes turning into a driveway the permitted reason among these choices. The rule is about the line marking, not about how slow the other vehicle is or whether you want to pass.
Why the other answers are wrong
- A. To pass a slow-moving truck. — A slow-moving truck is still another vehicle, and the double solid rule forbids passing it; slow traffic is not listed as an exception.
- C. To pass another car. — Passing another car is exactly what double solid lines prohibit, so this choice is not allowed.
- D. Under no conditions. — There is an exception: you may cross the lines to turn left into or out of a driveway or highway, so crossing is not banned under all conditions.
Remember it
Double yellow, no passing; a left turn into a driveway is the exception.
