What does a red light mean at an intersection?

At an intersection, a red light signifies that drivers must stop and wait until the light turns green. This rule is fundamental for maintaining safety on the roads, as it helps control the flow of traffic and reduces the likelihood of accidents. Stopping at a red light allows vehicles that have the right of way—those facing a green light—to proceed safely through the intersection.

While some choices may seem plausible, they do not align with the key traffic laws regarding red lights. For instance, proceeding with caution could lead to confusion and potential accidents, as it implies that a driver can move even when they are required to stop. Speeding up to clear the intersection poses a significant danger, as it could cause collisions with vehicles that are lawfully proceeding on a green light. Additionally, the suggestion to turn right if no cars are coming governs a different rule, but only applies under specific circumstances where a right turn on red is permitted after a full stop. This fact highlights that stopping completely at a red light is essential in all situations until the light changes.
