What condition may cause a cracked windshield to fail inspection?

A cracked windshield can lead to a failure during a vehicle inspection if it obstructs the driver's view. The primary purpose of a windshield is to provide safety and clear visibility for the driver. When the crack is positioned in such a way that it obstructs direct line of sight or affects the driver’s ability to operate the vehicle safely, it is deemed a serious safety concern.

The criterion for windshield conditions focuses on ensuring that the driver can see clearly without distractions or impediments. Therefore, any crack that compromises this visibility, regardless of its length or pattern, could lead to an automatic failure in the inspection process since it directly affects driving safety.

Understanding these standards is crucial for vehicle inspectors, as even small defects can pose significant risks on the road. The other options address various conditions related to windshield cracks, but none surpass the importance of unobstructed visibility in determining whether a vehicle can pass inspection.
