Final answer:
A small crack in your windshield should be repaired as soon as possible to prevent further damage and avoid safety risks or legal issues.
Step-by-step explanation:
If you notice a small crack in your windshield, it is important to repair it as soon as possible. While there is no strict deadline like "within 48 hours," it is advisable to address it promptly because cracks can quickly spread and worsen due to temperature changes, road conditions, and general vehicle vibrations.
Delayed repairs can lead to a need for a full windshield replacement, which is more expensive than a simple repair. Also, depending on where you live, driving with a damaged windshield may be against traffic laws and can pose a safety risk.
