What must a driver regularly check while driving to ensure a fair score?

The need for a driver to regularly check their mirrors while driving is crucial for maintaining situational awareness and ensuring safety on the road. Mirrors provide essential information about other vehicles and obstacles that may be present around the vehicle, enhancing the driver's ability to make informed decisions. By frequently checking the mirrors, a driver can stay aware of their surroundings, which is vital for avoiding accidents and responding appropriately to changes in traffic.

Regularly checking mirrors also helps a driver to be aware of blind spots, thereby improving their ability to change lanes safely or merge into traffic. This practice is a fundamental part of defensive driving, making it an important aspect that contributes positively to a driver's score during assessments of their driving performance.

On the other hand, focusing solely on road signs or passengers does not encompass the comprehensive awareness needed for safe driving. Road signs provide guidance and regulations, but they do not replace the necessity of monitoring the surrounding environment. Passengers, while a consideration for safety, do not impact the driver's ability to manage the vehicle and respond to potential hazards on the road. Thus, emphasizing the frequent checking of mirrors establishes a more proactive approach to driving safely and effectively.
