A traffic light displaying a green arrow and a red light means that:
- You may only drive straight ahead.
- You may drive only in the direction of the green arrow. ✓
- You must wait for a solid green light to proceed in any direction.
- Vehicles moving in any direction must stop.
Answer: B. You may drive only in the direction of the green arrow.
When a green arrow shows at the same time as a red light, you may drive only in the direction the arrow points.
Why this is the answer
The Texas handbook addresses this exact combination: a green arrow shown with a red light lets the driver go carefully in the arrow's direction, after yielding to other vehicles and pedestrians. The red light still blocks every other movement, so the arrow is the only permission you get. That is why proceeding straight or turning some other way is not allowed here, even though a plain steady green light would let you go straight or turn.
Why the other answers are wrong
- A. You may only drive straight ahead. — Going straight ahead is not what the arrow permits; a steady green light is what allows you to drive straight or turn, not a green arrow paired with a red light.
- C. You must wait for a solid green light to proceed in any direction. — You do not have to sit and wait for a solid green, because the green arrow with the red light already gives you permission to move in the arrow's direction.
- D. Vehicles moving in any direction must stop. — Traffic is not required to stop in every direction; the green arrow lets the driver facing it proceed in that direction.
Remember it
Think of the arrow as a narrow doorway: the red light shuts everything else, and only the arrow's path is open.
