Alberta Class 7 License Practice Test

Turning your headlights on at night is crucial for your safety and the safety of others on the road. The correct choice indicates that headlights should be activated when visibility is less than 150 meters. This guideline helps ensure that you can see and be seen by other drivers, which is essential in low-light conditions.

Headlights enhance your ability to see the road, obstacles, and other vehicles, especially when there may be insufficient street lighting. By ensuring your headlights are on in situations where visibility is compromised—specifically when you can't see clearly for more than 150 meters—you contribute to safer driving conditions during nighttime.

The other options, while they provide distance metrics, do not capture the essential requirement that you must use your headlights when visibility is below a certain threshold, making it important to prioritize when safety dictates their use. Turning on headlights before it gets too dark ensures that you have sufficient illumination to detect potential hazards and react accordingly, which is a key aspect of safe driving practices.
