What is a clear sign that a vehicle's alignment is off?

Uneven tire wear or pulling to one side is a clear and significant sign that a vehicle's alignment is off. When the wheels of a vehicle are not properly aligned, it can lead to uneven contact between the tires and the road surface, causing some areas of the tire tread to wear down more quickly than others. Additionally, a misalignment often results in the vehicle pulling to one side while driving, which can be dangerous and affect overall steering control. Recognizing these symptoms early can help in addressing alignment issues promptly, ultimately extending the life of the tires and ensuring safer driving conditions.

The other options, such as a fluctuating fuel gauge, glowing dashboard lights, or increased engine noise, pertain to different mechanical or electrical issues that do not directly indicate alignment problems. Understanding the specific signs of misalignment helps in correctly diagnosing and taking care of the vehicle's maintenance needs.
