Alberta Class 7 License Practice Test

Headlights are an essential safety feature in vehicles that help improve visibility for both the driver and other road users. They should be used in a variety of situations to enhance safety on the road.

Using headlights only at night is not sufficient, as visibility can be reduced during the day due to adverse weather conditions such as fog, rain, or snow. In these scenarios, turning on headlights helps other drivers see your vehicle better and assists with your own visibility. Foggy conditions are particularly challenging because the light can reflect off the fog, making visibility even worse; thus, using headlights is critical.

In addition, during rain or snow, the use of headlights is essential to ensure that you can see the road ahead and that other drivers can see you. This practice significantly reduces the chance of accidents in difficult weather conditions.

Overall, headlights should be used in all these situations – during the night and in poor visibility conditions such as fog, rain, or snow – making the comprehensive response to use them in all these contexts the correct choice.
