What must an operator do according to safety regulations?

The correct answer encompasses the idea that an operator must adhere to multiple safety regulations to ensure the safety of themselves and others on the road. Following traffic signs is crucial as they provide important information that helps regulate traffic flow and keep drivers informed about the rules of the road. Additionally, wearing safety gear such as helmets and reflective clothing is essential, especially in certain circumstances or types of vehicles, to protect against injuries. Driving during daylight can also enhance visibility and reduce the risk of accidents, but it is just one aspect of safe driving practices.

The inclusion of all these components underlines the importance of a comprehensive approach to safety regulations; operators are responsible for a range of actions rather than a singular one. Therefore, choosing the option that encompasses "all of the above" reflects a well-rounded understanding of the multiple facets of safety that operators must adhere to while on the road.
