North Carolina DMV Practice Test

Which system is likely causing a car to pitch and lean during turns?

1. Braking system

2. Transmission system

3. Suspension system

4. Exhaust system

The correct answer is: Suspension system

The suspension system is responsible for maintaining vehicle stability and handling during various driving conditions, including turns. When a car pitches and leans during turns, the suspension system's ability to absorb shocks and manage the weight distribution is compromised. A properly functioning suspension system includes components such as shocks, struts, springs, and anti-roll bars that work together to ensure that the vehicle remains level and stable while navigating curves. If the suspension is worn out or damaged, it can cause excessive body roll, leading to the car pitching and leaning as it tries to manage the forces acting upon it during a turn. While the braking system is essential for stopping and can affect weight transfer, it does not primarily control how a vehicle handles turns. The transmission system is related to how power is delivered to the wheels, which impacts acceleration and speed rather than vehicle dynamics during cornering. The exhaust system manages the flow of exhaust gases from the engine but has no direct influence on how a vehicle behaves when turning.
