Is It Illegal to Drive with a Cracked Windshield in Ontario?

A cracked windshield might seem like a small problem, but in Ontario, it can turn into legal issues, safety hazards, and even insurance complications. Many Ottawa drivers ask us the same question:
“Is it illegal to drive with a cracked windshield?”
The short answer: Yes — in certain situations.

In this guide, we’ll explain what the law says, when a cracked windshield becomes illegal, how it affects your safety, and what to do before the damage gets worse.

🔍 What the Law Says in Ontario

While Ontario doesn’t have a specific law that bans all cracked windshields, the Highway Traffic Act clearly states that your vehicle must be in safe operating condition.
If a crack affects your ability to see the road, you can be ticketed.

👉 Ontario Highway Traffic Act – Section 74
Drivers must have an unobstructed view of the highway.

When is it illegal?

Driving with a cracked windshield becomes illegal when the damage:

  • Interferes with the driver’s line of sight

  • Is larger than a credit card

  • Spreads across multiple areas

  • Includes starburst cracks or long-running fractures

  • Weakens the structural integrity of the windshield

Penalty:
You may receive a traffic ticket and could fail your Ontario Safety Standards Certificate if the crack is severe.

⚠️ Why a Cracked Windshield is a Safety Hazard

Your windshield is more than just a piece of glass—it’s a major safety component of your vehicle.

A cracked windshield affects:

  • Airbag deployment

  • Structural strength during a rollover

  • Visibility (especially at night or in sunlight)

  • Resistance to impact

Cracks usually spread faster in Ottawa due to cold weather, road vibrations, and temperature changes after defrosting your car.

🧭 Does a Cracked Windshield Fail a Safety Inspection?

Yes.
A vehicle with a crack in the driver’s viewing area or any damage that weakens the windshield will fail a safety inspection.

According to the Ontario Safety Standards Certificate (SSC) guidelines, windshields must be free from major defects that impair the driver’s view.

❄️ Why Cracks Spread Faster in Ottawa

Ottawa’s climate causes cracks to grow quickly because of:

  • Freezing temperatures

  • Salt on the roads

  • Heated defrost settings

  • Sudden temperature changes

If you leave a crack too long, it can spread across the entire windshield—even overnight.

🚫 So… Is It Illegal to Drive with a Cracked Windshield?

✔ Yes, if the crack blocks your view
✔ Yes, if it weakens structural integrity
✔ Yes, if it would cause your safety inspection to fail
✔ Yes, if a police officer determines it’s unsafe

Even if it’s not illegal yet, it can become illegal at any moment once the crack expands.
