Question Analysis

This question tests understanding of when to stop at traffic lights, a fundamental rule within driving. In California, according to Vehicle Code Section 21453, it is crucial to stop at solid red and flashing red lights. Flashing yellow lights do not require a full stop but indicate caution. The question involves understanding different scenarios with light signals and how each should be approached, hence requiring a moderate understanding of traffic laws.

Correct Answer Analysis

Correct Answer: Solid red lights, flashing red lights and yellow lights

The correct choice is 'Solid red lights, flashing red lights, and yellow lights' because in California, a solid red light requires a complete stop. Similarly, a flashing red light is treated like a stop sign. Yellow lights indicate that the light will soon change to red, so it advises drivers to stop if it is safe to do so, as codified in VC 21453.

Wrong Options Analysis

Option: Solid red lights, red arrows, and flashing yellow lights

This option is incorrect because while solid red lights and red arrows require stopping, flashing yellow lights do not require stopping but caution. Misunderstanding this could lead to unnecessary stops in traffic flow, causing potential hazards.

Option: Solid red lights, flashing red lights, and blacked out traffic signals

This option is incorrect because, while stopping at solid and flashing red lights is correct, blacked out traffic signals should be treated as an all-way stop intersection, which is not strictly a 'must always stop' situation but more of a cautionary approach, adhered per VC 21800(d)(1).
