What is the general observation about checking mirrors before an intersection?

The correct answer emphasizes the importance of checking mirrors at a specific distance from an intersection, with the guideline being at least 80 feet or less. This practice is vital for ensuring that a driver is aware of their surroundings and can react appropriately to other vehicles or pedestrians that may be present before making a turn or proceeding through the intersection.

Checking mirrors helps identify any approaching vehicles, cyclists, or pedestrians that could pose a risk, allowing for better decision-making and increased safety. The 80-foot mark is a practical recommendation that gives drivers enough time to make necessary adjustments, such as slowing down or changing lanes, before reaching the intersection.

By being aware of one's surroundings in advance, drivers can minimize the potential for accidents and maintain a smoother flow of traffic. This habit aligns with defensive driving principles, prioritizing safety by anticipating the actions of others on the road.
