Why ADAS Camera Recalibration Matters After a Windshield Replacement or Accident

Estimated reading time: 3 minutes

What Are Advanced Driver Assistance Systems (ADAS)?

Today’s vehicles are packed with safety technology. Features like lane keep assist, automatic emergency braking, and adaptive cruise control are all part of what’s known as Advanced Driver Assistance Systems (ADAS) — designed to help protect you on the road.

But here’s the key: ADAS only works properly when everything is set up exactly as the manufacturer intended.

Many newer vehicles rely on cameras mounted to the windshield as a core component of these systems. These cameras need to be aligned with extreme precision. Even a small change can affect how accurately your vehicle “sees” lane lines, other cars, or potential hazards.

When ADAS Recalibration Is Needed

Windshield-mounted ADAS cameras often need recalibration after certain types of work, including:

• A windshield replacement
• A vehicle accident — even a minor one
• Suspension or alignment work
• Significant impacts, potholes, or body repairs

Because these cameras are mounted directly behind the windshield, any change to the glass or vehicle alignment can throw them off. When that happens, your ADAS features may not function as intended.

Why This Is a Safety Concern

If ADAS cameras are out of calibration, your vehicle could:

• Misread lane markings
• Fail to brake when necessary
• Brake unexpectedly
• Give false warnings — or none at all

ADAS features help your vehicle make split-second decisions. When the cameras aren’t aligned correctly, those split-second decisions can put you at risk instead of keeping you safe.

Not All Repairs Are the Same

Recalibrating ADAS cameras isn’t a DIY job, and not every repair shop can handle it. Proper recalibration requires:

• Manufacturer-specific procedures
• Specialized equipment
• A controlled environment
• Trained technicians

That’s why recalibration should always be performed by a qualified repair facility that understands your vehicle’s ADAS technology.

What You Should Ask After a Repair

If you’ve recently had a windshield replaced or your vehicle repaired after an accident, ask one simple question:

“Were the ADAS cameras recalibrated?”

If you’re not sure, your repair shop or insurance provider should be able to confirm. It’s a small question that can make a big difference in keeping your safety systems working the way they’re supposed to.

The Bottom Line

Advanced Driver Assistance Systems are a powerful tool — but only when they’re properly maintained. Windshield camera recalibration isn’t something you can see, but it plays a critical role in keeping your ADAS features working as designed.
