A red traffic signal light means that you must:

1. Stop at the stop line.
2. Stop before entering any crosswalk.
3. Stop before entering the intersection.
4. All of the above. ✓

Answer: D. All of the above.

All of the above: a red light means you must stop at the stop line, before the crosswalk, and before entering the intersection.

Why this is the answer

The Texas handbook describes a steady red light as a stop signal: you stop before entering the crosswalk or the intersection. It also explains that where stop lines are painted at traffic signals, you must stop behind the stop line, and where stop lines are missing, you stop before the crosswalk. Read together, these points cover stopping at the line when present, before the crosswalk, and before the intersection, so the choice including all of them fits.

Why the other answers are wrong

• A. Stop at the stop line. — Stopping at the stop line is required when one is painted, but that alone leaves out the crosswalk and intersection stopping points in the red-light rule.
• B. Stop before entering any crosswalk. — Stopping before the crosswalk is only one part of the rule; it does not cover a painted stop line or the intersection itself.
• C. Stop before entering the intersection. — Stopping before the intersection is also only one part and misses the stop line and crosswalk requirements.

Remember it

Picture the order as line, crosswalk, intersection: red means stop before each one that applies.
