A cracked windshield might seem like a minor inconvenience — something you can ignore for a while. But the truth is, even a small crack in your car windshield can raise serious safety concerns. In many cases, continuing to drive with a damaged windshield puts you, your passengers, and other drivers at risk.
Here’s what you need to know about the dangers of windshield damage and why prompt auto glass repair matters.
How Dangerous Is a Windshield Crack?
Even minor cracks or small chips can weaken the structural integrity of your windshield glass. What starts as a small imperfection can quickly spread — especially with temperature changes, moisture, or even pressure from windshield wipers. Left unrepaired, a crack can turn into a broken windshield, compromising your safety in the event of a collision or rollover.
A cracked windshield also disrupts the unobstructed view every driver needs. If the damage is in the driver’s line of sight or on the driver’s side, it may distort your view of the road and reduce reaction time, increasing the risk of accidents.
Risks of Driving with a Compromised Windshield
Here are the main dangers of ignoring windshield damage:
- Reduced Visibility: Cracks in the driver’s view or across the entire windshield can create glares, distortions, or blind spots.
- Weakened Safety Support: In a crash, the windshield supports the roof and works with airbags. A compromised windshield may not hold up.
- Worsening Damage: Extreme temperature swings or hitting a bump can cause a small crack to spread along the edge of the windshield, leading to further damage.
- Insurance & Legal Issues: Some insurance companies won’t cover damage if you delay auto glass repair, and you might fail a safety inspection.

Can Small Chips Be Repaired?
Yes, a chipped windshield or small crack may be eligible for windshield repair — especially if it’s smaller than a loonie and not in the driver’s line of sight. Fast, affordable repairs can often be done in under an hour.
If the damage is too large or located near the edge of the windshield, windshield replacement is usually the safer option.
Will Insurance Cover Windshield Repair?
Many insurance companies in Canada cover windshield repair or replacement under comprehensive coverage, often without affecting your premium. Some policies even waive the deductible for small repairs, especially for auto glass.
Check your policy to see what’s covered — delaying repairs could result in higher costs or a denied claim if the crack spreads.
Final Thoughts: Don’t Risk It
Driving with a cracked windshield isn’t just annoying — it’s unsafe. It can affect your driver’s vision, reduce your vehicle’s crash protection, and result in more expensive repairs down the road.
Whether you’re dealing with a small chip or a large crack, it’s always safer to book a professional repair as soon as possible.
