Final answer:
When driving in dust or smoke, use low beams for better visibility and safety. High beams can make visibility worse by reflecting off particles, and hazard or parking lights should not be used while the vehicle is in motion.
Step-by-step explanation:
If you have trouble seeing other vehicles because of dust or smoke blowing across the roadway, you should drive slower and turn on your low beams. Using your low beams increases visibility in such conditions, helping you to see the road ahead and enabling other drivers to see your vehicle. High beams are not appropriate in this scenario because they can reflect off the dust or smoke, worsening visibility. Also, avoid using hazard lights while in motion, as this can confuse other drivers; hazard lights are typically for indicating that a vehicle is stopped or in distress. The same reasoning applies to parking lights; they are not suitable for poor visibility conditions while driving.
As a safety tip, always test the headlights on your car before traveling to ensure they are functioning properly. Good visibility is crucial for safe driving, especially in adverse conditions like dust or smoke. Remember, it is important for your safety and the safety of others to use appropriate lighting and drive with caution under such circumstances. Warning: Do not look directly at very bright light, as this can cause damage to your eyes.
