Prioritizing safety during refueling involves ensuring that there are no distractions or additional risks that could lead to accidents or incidents. This is why ensuring no riders are present is a critical consideration. When a vehicle is being refueled, it’s vital to minimize any potential dangers, including the risk of ignition or spills.

Having passengers on board can divert a driver's attention or complicate the process, as they may need to exit or remain still, leading to potential hazards. Therefore, removing all riders helps maintain a controlled environment focused on safety.

While the presence of distractions and the promptness of completing the refueling process are also important, they are secondary to ensuring that the vehicle is free from any passengers who could inadvertently cause a disruption or pose a safety risk during what can be a hazardous activity.
