There is no definite answer to how long you can drive with a cracked windshield. In some cases, the crack may be small and unlikely to spread, so you may be able to drive for days, weeks, or even months without further damage. However, it is important to consider the size and severity of the damage when deciding how soon to replace your windshield. Any additional impact, such as potholes in the road, can cause even small chips on the windshield or a small crack to become a bigger problem.
Dirt and dust can also get into the chip or crack, which can prevent the resin from adhering to the glass as it should. Therefore, it is best to repair a broken windshield as soon as possible to avoid having to replace the entire windshield in the future. Wearing your windshield on time is the best way to ensure that no dirt or dust accumulates inside chips or cracks. Depending on the size of the crack, you may be able to repair the windshield instead of replacing it.
Whatever the reason, drivers should consider repairing or replacing their windshield to prevent further damage. Repairing damage quickly helps prevent further damage from occurring that could result in the need to replace the windshield, rather than simply repairing it.
