Why is a clean windscreen important when driving into low sun?
Answer and explanation
Correct answer: D. Dirt scatters the sunlight into glare
- Step 1: Smears light up in strong sun. Step 2. Keep the glass clean inside and out. Answer: Dirt scatters the sunlight into glare. Why not the others: Dirt on the glass reduces the temperature of the engine: dirt has no effect on the engine. Dirt on the glass increases tyre wear at speed: tyres are unaffected. Clean glass lowers the car's speed in sunlight: clean glass has no effect on speed.
