Alberta Class 7 License Practice Test

The reason to check mirrors frequently while driving is primarily to maintain awareness of the surrounding environment and ensure safety. This includes understanding the position of other vehicles, identifying potential hazards, and being watchful for pedestrians.

When checking mirrors, a driver can see vehicles approaching from behind and assess their speed, position, and intentions, which helps in making informed decisions while driving. However, assessing the speed of your own vehicle is typically done by monitoring the speedometer rather than relying on mirrors. Thus, checking mirrors is not necessary for this specific purpose, making it the option that does not align with the primary reasons for frequent mirror checks.
