When approaching a traffic signal, what should drivers always ensure?

Answer: C — They know the meaning of all traffic signals

When approaching a traffic signal, it is crucial for drivers to know the meaning of all traffic signals. This understanding is essential to ensure safe driving behavior and compliance with the rules of the road. Each signal conveys specific instructions regarding when to stop, go, or proceed with caution. Misinterpreting a signal can lead to accidents, violations, and endanger not only the driver but also other road users including pedestrians and cyclists. While familiarity with local traffic laws, ensuring the road is clear of other vehicles, and observing pedestrians waiting to cross are all important aspects of safe driving, knowing the meanings of traffic signals directly relates to the specific actions drivers need to take when they encounter them. This knowledge helps drivers make informed decisions in varying traffic situations, enhancing overall road safety.
