Final answer:
When driving in smoky or foggy conditions, it is not recommended to use high-beam bright lights as they can worsen visibility and create glare. Low-beam lights or fog lights are better suited for these conditions. However, in rare cases where other drivers are also using high-beam lights, it may be acceptable to use them.
Step-by-step explanation:
When driving in smoky or foggy conditions, it is not recommended to use your high-beam bright lights (option b: No, never). This is because high-beam lights can actually worsen visibility in such conditions by reflecting off the particles in the air, creating glare and reducing contrast. It is best to use your low-beam lights or fog lights, if your vehicle is equipped with them, as they are designed to provide better visibility in these conditions.
Using high-beam bright lights in smoky or foggy conditions can also be dangerous for other drivers on the road as it can blind them and make it difficult for them to see properly. It is important to always prioritize the safety of yourself and others on the road.
However, it is worth noting that in some rare cases, if other drivers in the same area are also using their high-beam lights, you can use your high-beam lights as well (option c: Only if other cars are using them). This can help improve visibility for everyone while maintaining a similar level of brightness. Overall, it is crucial to assess the specific conditions and prioritize safety when deciding whether to use high-beam lights in smoky or foggy conditions.
