This question focuses on the concept of blind spots in vehicle operation. In Ontario, and universally, a blind spot refers to areas around the vehicle that cannot be easily seen through the driver's rear or side-view mirrors. Understanding blind spots is critical for safe driving, as it prevents collisions that may result from not seeing another vehicle present in these areas. It corresponds with Traffic Act guidelines regarding the importance of blind spot awareness. Blind spots typically include spaces directly behind and on the sides of the car where other vehicles may not be visible in the mirrors. Drivers are taught to physically check these areas by turning their head, especially before changing lanes or merging, as part of the G1 test standards.
