Checking your mirrors every 5-8 seconds is essential for maintaining situational awareness while driving. This frequency allows you to keep an eye on surrounding vehicles, potential hazards, and changes in traffic conditions. It enables you to respond promptly to emergencies or adjust your driving strategy as needed.

By checking your mirrors regularly, you develop a habit of being aware of your surroundings, which is crucial for safe driving. This practice not only helps in identifying vehicles in your blind spot but also aids in anticipating the actions of other drivers. For example, if you notice a car that is rapidly approaching from behind, you can make informed decisions regarding your lane changes or speed adjustments.

Less frequent checks, like every 10-12 seconds or longer intervals, may leave you vulnerable to sudden changes in the environment, as you might miss critical information about what is happening around you. On the other hand, checking every 2-3 seconds may be excessive and distracting, making it challenging to focus on the road ahead. Thus, the 5-8 seconds interval strikes a balance, allowing you to stay vigilant without compromising your concentration on driving.
