Do not pass:
- On a hill.
- In a curve in the roadway.
- In an area where visibility is limited.
- All of the above. ✓
Answer: D. All of the above.
Do not pass on a hill, in a curve in the roadway, or in any area where visibility is limited — all of those choices are correct.
Why this is the answer
The Texas handbook lists the places where you must never drive on the left side of the road. Among them: on a hill, on a curve, or in any other spot where your vision is limited. Each of the three situations named in the other choices appears on that list, so each one on its own is a real no-passing situation, and the choice that covers all of them is the complete answer. The handbook also ties this to markings, saying a solid yellow line on your side marks a no-passing zone.
Why the other answers are wrong
- A. On a hill. — A hill is only one of the places named in the handbook where passing is off limits, so this choice leaves out the curve and the limited-visibility spots.
- B. In a curve in the roadway. — A curve in the roadway is likewise just one item on the handbook's list, so picking it alone ignores the hill and the places where you cannot see well.
- C. In an area where visibility is limited. — Limited visibility is another single item on that same list, and choosing it by itself drops the hill and the curve.
Remember it
If you cannot see far enough ahead to know the road is clear, stay in your lane — hills, curves, and blind spots all belong to the same no-passing family.
