Crack vs. Chip - A Guide to Different Types of Windshield Damage

A chip occurs when a small object, like a rock or piece of debris, strikes the windshield, causing a small piece of glass to come off. Chips are usually circular or star-shaped. The impact point is often noticeable, with tiny cracks radiating outward. Depending on the size and location, chips can sometimes be repaired, preventing further damage and maintaining the windshield's structural integrity.

Bullseye: Circular damage that marks the impact point.

Star Break: Features short radial cracks emanating from the impact point, creating a starburst pattern.

Combination Break: A complex form of damage that includes multiple types of breaks.

A crack is a distinct line that runs across the windshield. Cracks can vary in length, from less than an inch to the width of your windshield. These auto glass cracks can be caused by the impact of weather but are also often the result of stress from temperature changes or structural weakening over time. Cracks, especially those that are long or intersecting, typically require windshield replacement.

Stress Crack: Occurs without direct impact, often due to extreme temperature changes.

Edge Crack: Starts within 2 inches of the windshield's edge, likely to spread quickly.

Floater Crack: Begins in the center of the windshield, away from the edges.

Both chips and cracks can impair your vision while driving, but the extent varies. A small chip might be a minor annoyance, whereas a large crack can significantly obstruct your line of sight. Moreover, the windshield contributes to the vehicle's structural integrity, especially during a rollover accident. Therefore, addressing any damage promptly is essential for safety.

Chips can often be repaired if they are smaller than a quarter and not directly in the driver's line of sight. Repairing a windshield chip involves injecting a clear resin into the damaged area, which is then cured and polished.

Cracks, particularly long or deep ones, usually necessitate windshield replacement. Repair techniques are not effective for extensive cracks, as they cannot restore the windshield's original strength and clarity.

While you can't avoid every hazard on the road, you can minimize risks by maintaining a safe distance from trucks or vehicles carrying debris, avoiding rapid temperature changes (like using boiling water to defrost your windshield), and parking in shaded areas whenever possible.

Distinguishing between a chip and a crack is the first step in addressing windshield damage. While some chips can be easily repaired, preventing further damage, cracks often require a complete windshield replacement to ensure safety and visibility. Regardless of the type of damage, prompt attention is crucial to maintain your vehicle's integrity and protect yourself and your passengers.

When considering the signs indicating the need for a windshield replacement, it becomes even more imperative to address any chip or crack promptly. This proactive approach ensures the continued safety of your vehicle and prevents the damage from worsening.
