The correct answer is (d) Stop immediately if an obstacle is detected. This is vital for safe driving and avoiding accidents when backing up a vehicle. Driver's education emphasizes the importance of being alert and responsive while using mirrors and checking for hazards.
Step-by-step explanation:
When backing up in a vehicle, it is important to do a 360-degree check for hazards and use mirrors effectively. Option (d) Stop immediately if an obstacle is detected is the correct procedure when backing up a vehicle. It is crucial to be vigilant and responsive to any potential obstacles to prevent accidents and ensure safety. While the question mentions mirrors and checking for hazards, the context of the question suggests it is related to driver's education or safety protocols while operating a vehicle, which would be categorized under Health education within a school's curriculum.
Utilizing rear-view and side mirrors while backing up aids in maintaining awareness of your surroundings. However, if a hazard is observed during this process, the driver must come to an immediate halt to reassess the situation and prevent potential collisions or accidents.
