When the traffic signal light is red and you intend to go straight, what must you do?

When you encounter a red traffic signal while intending to go straight, the appropriate action is to stop completely. This rule is essential for maintaining safety and adherence to traffic laws. A red light indicates that vehicles must halt at the intersection, allowing other traffic and pedestrians to clear safely.

Once you have come to a complete stop, you must wait until the signal turns green. This requirement ensures that traffic flows smoothly and prevents accidents that could arise from failing to heed the signal. After the light turns green, you should then check for any pedestrians or other vehicles before proceeding, ensuring the way is clear.

This answer emphasizes the importance of fully obeying traffic signals. Unlike other responses that suggest proceeding under various conditions, it is crucial to remain stopped until authorized by the signal change. This precaution not only helps in avoiding potential collisions but also reinforces the orderly conduct of traffic at intersections, which is vital for road safety.
