Why is it important to check the alignment of a vehicle?

Checking the alignment of a vehicle is crucial because it ensures that the vehicle tracks straight while driving. Proper alignment means that all wheels are parallel to each other and perpendicular to the ground. When a vehicle is misaligned, it can cause the tires to wear unevenly, leading to increased tire replacement costs and negatively impacting the vehicle's handling and safety.

When the wheels are aligned correctly, the vehicle will not pull to one side, making driving more stable and predictable. Additionally, proper alignment contributes to improved fuel efficiency, as misaligned wheels can increase drag and resistance, causing the engine to work harder. However, the primary importance of alignment concerns the vehicle's ability to track straight and maintain control on the road.

Other choices relate to different aspects of vehicle maintenance and operation, but do not directly address the specific function and significance of wheel alignment in vehicle safety and efficiency.
