When a driver is blinded by the sun, he should:

1. Look as low as possible to the roadway, to avoid blinding.
2. Overtake the vehicle in front because it is better to drive on an open roadway.
3. Stay close to the vehicle in front, so it can block the sun for him.
4. Correct answer: Slow down in accordance with his range of vision and use the sunshade.

WhyIf the sun blinds you, slow down to match what you can see and use the sun visor. Looking away or closing up to the car ahead is dangerous.
