Question

To improve visibility caused by rain or fog, drivers should use:

1) low beam headlights
2) high beam headlights
3) parking lights

Answer 1

Drivers should use low beam headlights in rain or fog to improve visibility, as high beams can cause glare. Parking lights do not provide sufficient visibility for safe driving in these conditions.

Step-by-step explanation:

When visibility is reduced due to rain or fog, drivers should use low beam headlights. High beam headlights can reflect off the raindrops or fog particles, causing a glare which makes it even harder for drivers to see. The correct use of headlights is essential for ensuring safety on the road during adverse weather conditions.

Parking lights are not sufficient in providing the necessary visibility and are not recommended for driving in poor visibility conditions. Additionally, it's important to recognize that light rain can mix with oil and gasoline on the road surface, leading to slippery conditions and potentially reducing a vehicle's control, whereas heavy rain might wash away some of that build-up, possibly improving traction slightly but also reducing visibility.
