Which of the following statements regarding blind spots is true?

The statement that emphasizes checking your blind spot before changing lanes is crucial for safe driving. Blind spots are areas around a vehicle that cannot be directly observed by the driver through standard mirrors. These areas can vary significantly in size depending on the vehicle's type and dimensions, especially in larger vehicles like trucks and buses, which often have more extensive blind spots.

Always checking your blind spot helps prevent collisions with other vehicles, pedestrians, or cyclists that may be in those areas. While mirrors can provide visibility on the sides and rear of the vehicle, they do not cover every angle, thereby creating these blind spots. Therefore, making it a habit to turn your head and look over your shoulder before changing lanes ensures greater awareness of your surroundings and enhances overall road safety. This practice is an essential part of defensive driving and helps reduce the risk of accidents.
