What does a solid red traffic signal indicate?

1. Prepare to stop

2. Stop and wait until the light turns green

3. Proceed with caution

4. Turn left safely

The correct answer is: Stop and wait until the light turns green

A solid red traffic signal indicates that drivers must stop their vehicles. The primary purpose of a red light is to control the flow of traffic and ensure safety at intersections. When a red signal is illuminated, vehicles are required to come to a complete stop at the designated stop line, intersection, or before entering the crosswalk. The driver must remain stopped until the light changes to green, at which point they can proceed safely through the intersection. Understanding this context is crucial for driving safely and following the rules of the road. The other choices do not accurately reflect the requirement of coming to a complete stop, which is the fundamental rule associated with a solid red traffic signal.
