6 Ways to Stop Windshield Cracks from Spreading While Traveling

Federico A

Your car’s windshield is more than just a window to the world; it’s a critical safety component. A cracked windshield not only obstructs your vision but can also compromise the structural integrity of your vehicle. When you’re on the road, the last thing you want is for a tiny chip to turn into a sprawling crack. In this blog post, we’ll explore six effective ways to prevent windshield cracks from spreading while you’re traveling.

1. Seek Professional Help

The moment you notice a chip or crack on your windshield, your first step should be to consult a professional auto glass repair service. They can assess the damage and recommend the best course of action, whether it’s a repair or replacement. In many cases, a timely repair can prevent the crack from getting worse.

2. Use Clear Nail Polish

If you’re in a pinch and can’t immediately visit an auto repair shop, clear nail polish can be a temporary fix. Simply apply a thin layer of clear nail polish over the chip or crack. This will help prevent dirt and moisture from getting into the crack and spreading it further.

3. Avoid Extreme Temperature Changes

Drastic temperature changes can exacerbate windshield cracks. Avoid exposing your vehicle to sudden temperature shifts, such as parking in direct sunlight and then using your air conditioner. Gradual changes are less likely to worsen the damage.

4. Drive Cautiously

Driving over rough terrain or hitting potholes can put additional stress on your windshield and lead to crack expansion. When traveling, try to avoid bumpy roads or slow down when you encounter uneven surfaces to reduce the risk of further damage.

5. Keep a Safe Following Distance

Maintaining a safe following distance from the vehicle in front of you is not just a good driving practice; it can also prevent windshield damage. Flying debris from the road can easily lead to chips and cracks if you’re tailgating. By keeping your distance, you reduce the chances of your windshield being struck by debris.

6. Replace Worn Wiper Blades

Worn-out wiper blades can put unnecessary pressure on your windshield, potentially causing the damage to spread. Regularly inspect and replace your wiper blades to ensure they are in good condition. Properly functioning wipers will reduce friction on the glass and extend the life of your windshield.


Your windshield is more than just a piece of glass; it’s a vital safety feature. When you’re on the road, taking steps to prevent windshield cracks from spreading is essential for your safety and the longevity of your vehicle. Whether you’re seeking professional repairs, using temporary fixes, or simply driving with caution, these six tips can help you safeguard your windshield while traveling. Remember, a small chip or crack doesn’t have to become a big problem if you act promptly and wisely. Safe travels!
