When should you use your headlights while driving a commercial vehicle?

Answer: B — Whenever visibility is less than 500 feet or during inclement weather

Using your headlights whenever visibility is less than 500 feet or during inclement weather is crucial for ensuring safety on the road. This guideline is particularly important in adverse conditions such as heavy rain, fog, snow, or dust storms, where visibility can be significantly reduced. By turning on your headlights in these situations, you enhance your own visibility to other drivers and also make it easier for you to see the road ahead. This practice is aligned with safe driving regulations and is a requirement in many areas, as it helps to prevent accidents and allows you to react appropriately to any hazards that may arise due to poor visibility. Operating with headlights in such conditions plays a key role in maintaining road safety, especially when driving a larger and often more difficult-to-maneuver commercial vehicle. It's important to be proactive about visibility at all times to protect yourself and other road users.
