What does a solid red light mean?

A solid red light indicates that drivers must come to a complete stop at the designated stop line or before entering the intersection. This rule is crucial for ensuring safety and maintaining the flow of traffic. While waiting for the light to change, drivers should remain alert and be prepared to proceed only when the light turns green, ensuring that the intersection is clear of other vehicles and pedestrians.

Other options may suggest alternative actions that could lead to confusion or unsafe situations. For instance, proceeding with caution could result in misjudging the right of way, while turning right immediately without checking for oncoming traffic or pedestrians might lead to an accident. Similarly, slowing down and preparing to stop, while somewhat aligned with safety, does not fulfill the requirement to stop fully before the red light. Understanding the significance of a solid red light reinforces the importance of obeying traffic signals for the safety of all road users.
