Final answer:
The primary means by which a driver gains information needed to drive safely is through seeing. Visual observation is crucial for maintaining situational awareness and detecting potential hazards on the road.
Step-by-step explanation:
The question pertains to driver's education and the primary means by which a driver gains the information necessary to drive safely. The correct answer out of the given choices is seeing, as visual observation is vital for situational awareness on the road. A driver gathers crucial information about their surroundings through sight, such as noticing pedestrians, observing traffic signals, and being aware of other vehicles.
Other options, such as talking to yourself, following other traffic, and turning the radio do not directly contribute to the acquisition of safety-related information. Additionally, practices such as using hands-free devices while driving, keeping phones away from the body, and not using a cellphone without an external antenna are also important for minimizing distractions and radiation exposure. Observing safety habits like wearing seatbelts, using headlights appropriately, and not engaging in risky behavior also contribute to safer driving experiences.
