Which of the following is NOT a physical aspect of driving?

Perception is the correct choice because it pertains to the mental processing of information, rather than a physical action involved in driving. Braking, steering, and accelerating are all physical actions that a driver must perform while operating a vehicle. These actions involve the use of physical controls to maneuver and manage the vehicle's speed and direction. In contrast, perception involves the awareness and interpretation of environmental cues, such as recognizing traffic signals, assessing distances, and noticing the behavior of other road users. This cognitive function is crucial for safe driving but does not fall into the category of physical aspects. Thus, understanding the distinction between physical actions and cognitive processes is essential for comprehensive driving education.
