Understanding Windshield Tint & Shade Bars: What’s Legal in BC?

Tinted windows aren’t just about style - they can help reduce glare, increase privacy, and block UV rays. But when it comes to your windshield, the rules are a little stricter.

Whether you're thinking about tinting your windshield, wondering about that blue or grey strip at the top, or you're not sure what’s allowed to be stuck to the glass, here’s what you need to know.

What’s a Shade Band (aka Shade Bar)?

That slightly darker strip at the top of your windshield is called a shade band or shade bar. It’s there for a good reason: to help block the sun from hitting your eyes at just the wrong angle, especially during early morning or evening drives.

Shade bands are usually factory-installed and come in tones like blue, grey, green, or bronze. They’re completely legal - as long as they don’t extend too far down.

Windshield Tinting Laws in BC

In British Columbia, aftermarket tinting on windshields is not permitted - with one exception:

✓ Permitted:

• A factory-installed shade band that doesn’t go below the top 75 mm (3 inches) of the windshield

• Optically clear UV-blocking window film

  
  

✗ Not permitted:

• Tint film or spray applied to the rest of the windshield

• Any aftermarket tint that reduces visibility or affects the driver's clear view

If a tint goes beyond the legal limit, it can lead to a fine - and more importantly, it could reduce your safety in low-light or rainy conditions.

What’s Allowed to Be Affixed to the Windshield?

British Columbia has clear rules when it comes to what can be attached to your windshield - and the key reference point is the AS-1 line.

What is the AS-1 Line?

The AS-1 line is a marking near the top edge of your windshield, typically about 75 mm (3 inches) down from the top. According to BC’s Motor Vehicle Act Regulations, nothing may be affixed to the windshield below this line unless specifically exempt (such as a rearview mirror).

That means even common items like:

• Parking passes

• Dash cams

• Toll tags

• Phone or GPS mounts

…are technically not permitted if they’re placed below the AS-1 line and within the driver’s field of vision.

✗ What’s Not Allowed:

• Any item affixed below the AS-1 line

• Stickers, decals, or suction devices that block or reduce the driver’s view

• Hanging objects (e.g. air fresheners) that may obstruct visibility

✓ What Is Permitted:

• Factory-installed or approved rearview mirrors

• Dash cams or toll devices, if affixed above the AS-1 line and outside the driver’s view

• Items attached to rear side or rear windows, where there are fewer restrictions

Visibility Is Key

The underlying rule is all about visibility. If it blocks your view or creates a distraction, it’s likely to be deemed illegal - even if it seems minor. While many drivers affix items like parking permits to the windshield, this is still considered a violation and may result in a fine if enforced.

Local tip:

We always recommend placing anything affixed to the windshield low and off to the passenger side. If you're not sure it’s legal, it's probably safer to move it.

Rear Windows: More Flexibility

Unlike the front windshield, rear side and rear windows in BC can be tinted without specific VLT (Visible Light Transmission) limits. You’re legally allowed to tint these windows as dark as you like, as long as:

• Your vehicle is equipped with dual side mirrors to compensate for limited rear visibility

• The tint does not impair your ability to see out or cause a safety concern

Window Tint Penalties and Rear Window Rules in British Columbia

It’s important to follow BC’s window tinting laws to avoid fines or safety issues. If your tint doesn’t meet provincial standards, you could face penalties including tickets or orders to remove illegal tinting.

Keep in mind: Window tinting laws vary across Canada. What’s legal in BC may not be allowed in provinces like Ontario or Quebec. If you’re traveling outside BC, always check the local tint laws to stay compliant and avoid fines.

Bonus Tip: Removing Old Stickers or Adhesive Safely

Got an old sticker or pass that won’t come off? Don’t scrape - this can leave micro-scratches. Use warm soapy water and a plastic card (like a loyalty card) to gently peel it off. If it’s stubborn, we can help you remove it safely in-shop.
