Which of the following is NOT a driving task model?

• A. Control
• B. Guidance
• C. Navigation
• D. Perception

Answer: (D)

Perception is not a driving task model. Driving task models describe the deliberate ways a driver acts to operate the vehicle and reach a destination: controlling the vehicle to manage speed and stability, guiding the vehicle to stay on the intended path, and navigating to plan and execute routes. Perception, by contrast, is about sensing the environment—the information the driver uses to decide what to do within those task models. For example, noticing a red light or a pedestrian provides input, and the appropriate driving task responses are braking, steering, or changing course. Because perception is about sensing rather than outlining a method for performing the driving tasks, it isn’t considered a driving task model.
