What is the function of the suspension system?

• A. To generate power for the engine.
• B. To regulate airflow.
• C. To support the weight, absorb road shocks, and keep tires in contact with the road.
• D. To cool the engine.

Answer: (C)

The suspension system’s job is to support the vehicle’s weight, absorb road shocks, and keep tires in contact with the road. This combination is essential for ride comfort, stable handling, and effective braking and steering, especially on rough surfaces. When the suspension absorbs bumps, it prevents excessive body movement and helps maintain grip at the tires, so the vehicle responds predictably to steering inputs and braking forces.

Other options refer to different systems: generating power for the engine comes from the engine itself, not the suspension; regulating airflow is part of the intake/ventilation system; and cooling the engine is handled by the cooling system. Understanding this function helps you assess ride quality and safety during vehicle inspection and operation.
