A shattered or cracked rear windshield isn’t just a nuisance—it’s a serious safety risk. Many drivers are unsure whether it’s legal or safe to keep driving with broken rear glass. The truth is, it depends on the severity of the damage, but in most cases, you should get it repaired or replaced immediately.
At RAM Auto Glass, we replace broken back glass with same-day mobile service across Vaughan, Richmond Hill, and surrounding areas. If your rear windshield is broken or missing, here’s what you need to know before getting back on the road.
What Counts as a “Broken” Rear Windshield?
The rear windshield—also called the back glass—is typically made of tempered safety glass, which shatters into small pieces when broken. This glass can’t be repaired; once it’s cracked or shattered, it must be replaced.
Damage that qualifies as broken includes:
- Large cracks spanning most of the surface
- Full shattering with glass fragments missing
- Holes or punctures from impact
- Complete collapse of the rear window
Is It Legal to Drive With a Broken Rear Windshield?
Ontario’s Highway Traffic Act doesn’t explicitly prohibit driving with a broken rear windshield—as long as your side mirrors provide a clear rear view. However, if the damage affects your visibility or poses a safety hazard (like falling glass), you can be pulled over and fined.
According to Ontario Regulation 611, all vehicle glass must be in “good condition” and not obstruct the driver’s view. If police determine your vehicle is unsafe, they can issue a defect notice or remove it from the road.
Risks of Driving With Broken Rear Glass
- Reduced visibility: You lose one of your three critical sightlines when checking blind spots or reversing.
- Compromised cabin security: Easy access for theft or weather damage to your interior.
- Sharp glass fragments: Loose or falling debris can injure passengers or create distractions.
- Increased air pressure: Especially at highway speeds, broken glass affects the aerodynamics and cabin seal.
While some people use temporary fixes (like plastic wrap or cardboard), these are not safe for long-term driving and could lead to tickets or insurance complications.
Back Windshield Replacement Is Quicker Than You Think
Unlike front windshields, rear glass doesn’t have sensors or wiper mounts in most vehicles. That means it can usually be replaced in under 90 minutes by a mobile technician.
At RAM Auto Glass, we match your original tint, defrost lines, and fitment—so your new back glass performs like factory original. Most replacements are covered by insurance and come with a warranty-backed installation.
Can You Claim It Through Insurance?
Yes. If you have comprehensive coverage, broken rear glass is typically included. In many cases, there’s no deductible for back glass replacement, especially if it’s a glass-only claim.
We’ll help you file the claim and can bill most major providers directly—no phone tag required.
