What condition must the turn signal lights be in for the vehicle passing the driving test?

The requirement for the turn signal lights to be operational is crucial for successfully passing a driving test. Operational turn signals are essential for indicating a driver’s intentions to other road users, ensuring safety and compliance with traffic laws. When signaling is done properly, it informs other drivers and pedestrians about upcoming maneuvers such as turning or lane changes, and it helps to prevent accidents.

While other choices touch on various aspects of safety or vehicle maintenance, they do not directly address the essential operational status needed for the exam. For instance, having bright colors might be beneficial for visibility, but it does not matter if the lights are not functioning. The test emphasizes the importance of having all required signaling devices working as intended to demonstrate a candidate's readiness for safe driving practices.
