What are the three forces controlled by the driver?

• A. Braking, steering, and signaling
• B. Acceleration, steering, and visibility
• C. Acceleration, braking, and steering
• D. Throttle, braking, and direction

Answer: (C)

The main idea is that a driver directly controls three aspects that change the vehicle’s motion: how fast you go, how you slow down or stop, and where you’re headed. Acceleration is controlled by the throttle to speed up, braking reduces speed, and steering determines the vehicle’s path by changing direction. Signaling or visibility don’t alter the vehicle’s motion, so they’re not the forces the driver actively uses to control movement. Among the options, acceleration, braking, and steering best capture the three operative inputs that drive the car’s dynamics. The term direction is less precise than steering, so the standard descriptor is acceleration, braking, and steering.
