When visibility on the road is poor, the driver should:

1. Correct answer: Slow down, adjust his speed to the visibility conditions and turn-on his dipped beam.
2. On a two-way road – slow down; and on a one-way road – continue driving normally.
3. Accelerate and turn-on the rear lights, to prevent collision with the vehicle driving behind.
4. Turn-on the high beam to extend the field of vision and warn the incoming traffic from your opposite direction.

WhyIn poor visibility, slow down to match what you can see and turn on your low beams. High beams dazzle in such conditions.
