Final answer:
In low visibility conditions and when driving at a reduced speed, you should turn on your vehicle's hazard/flashers to enhance visibility and communicate with other drivers.
Step-by-step explanation:
When driving in lower visibility conditions at a greatly reduced speed, turning your hazard/flashers on is the recommended action. This will make your vehicle more visible to other drivers and warn them that you are travelling at a slow pace. It is important to use your vehicle's lights properly to communicate with other drivers and enhance safety on the road.
Remember not to use high-beam headlights in foggy conditions as they can reflect off the fog and actually decrease visibility. Fog lights and brake lights serve different purposes; fog lights improve your visibility to others without causing glare, while brake lights indicate that you are slowing down or stopping.
