Final answer:
While a vehicle is in motion, the driver should focus exclusively on driving to ensure the safety of all passengers and other road users. Distractions like chatting with passengers or making change can lead to dangerous situations, and allowing passengers to stand can result in injury if the vehicle stops abruptly or is involved in a collision.
Step-by-step explanation:
When a vehicle is in motion, the driver should always focus on driving. This means that the driver should not engage in activities that could distract them from the road such as making change for passengers, chatting excessively with passengers, or allowing passengers to stand up and move around the vehicle while it is moving. The primary task of the driver is to ensure the safety of everyone inside the vehicle as well as other road users. This includes maintaining control of the vehicle at all times, being aware of the surrounding traffic, and adhering to traffic laws.
From a health and safety perspective, allowing passengers to stand while the vehicle is in motion could lead to injuries if the vehicle were to stop suddenly or be involved in a collision. Similarly, being distracted by making change or engaging in conversations could take the driver's attention away from potential hazards on the road.
