What is ADAS?
ADAS stands for advanced driver assistance systems: the features that watch the road and warn you or step in. Many of them depend on a camera mounted to the inside of the windshield, usually behind the rearview mirror.
Systems that commonly rely on that windshield camera:
- Lane departure warning and lane keeping assist
- Forward collision warning and automatic emergency braking
- Adaptive cruise control (often together with a radar in the grille)
- Traffic sign recognition
- Automatic high beams
- Pedestrian and cyclist detection
Some cars also use radar, side cameras or parking sensors. Those can need their own calibration after body or bumper work, but the windshield camera is what glass work affects.
When is calibration required?
Calibration is required when the automaker's repair procedure calls for it. That depends on the manufacturer, not on state law. Common triggers:
| Event | Calibration needed? |
|---|---|
| Windshield replacement | Required by most automakers when a forward camera is present |
| Camera removed or bracket disturbed | Usually required |
| Wheel alignment (thrust angle change) | Often required |
| Collision, even a minor one | Often required, depending on what was hit |
| Suspension lift, lowering or ride height change | Often required |
| Warning light for the camera system | Diagnose first, then calibrate if needed |
A camera aimed even a fraction of a degree off can misjudge lane lines or the distance to the car ahead. The result may be a system that warns late, brakes when it shouldn't, or turns itself off.
Static vs. dynamic calibration
The automaker decides which method your car uses. Some cars need one, some need both.
| Static | Dynamic | |
|---|---|---|
| Where | Parked in a level, controlled, well-lit space | Driving on public roads |
| How | Printed targets set at exact distances and heights from the car | Scan tool connected while driving at set speeds |
| Typical time | Up to about 1 to 3 hours | About 30 to 60 minutes of driving |
| What can delay it | Uneven floor, poor lighting, clutter | Rain, faded lane lines, heavy traffic |
| What you do | Leave the car with us | Nothing, we drive it |
The method can change between models and even model years of the same brand. The VIN lookup is what tells us for certain. For the full comparison, read static vs. dynamic calibration.
How we calibrate your camera
- VIN lookup. We pull the factory calibration procedure for your exact vehicle, including the required method and conditions.
- Pre-scan. We scan the car's modules for stored fault codes before we touch anything, so existing problems are on record.
- Calibration. We run the static, dynamic or combined procedure exactly as the automaker specifies.
- Post-scan. We scan again to confirm the calibration completed and no new codes were set.
- Printed result. You get a written record of what was done and whether it passed.
Dynamic calibration is only done after the windshield's safe drive-away time has passed, which is what industry installation standards call for.
Where calibration happens
Most calibrations happen right where your car is parked. Dynamic calibrations are done on nearby roads with clear lane markings and steady speeds. Static calibrations are done on a level driveway or parking lot with good light and enough room for the targets. If your vehicle's static calibration can't be done safely where it's parked, we tell you before we book and explain your options.
How long does ADAS calibration take?
Most calibrations take 30 minutes to 2 hours. Dynamic calibration usually takes 30 to 60 minutes of driving. Static calibration can take up to about 1 to 3 hours, including setup. Cars that need both take longer.
What does ADAS calibration cost?
Calibration alone starts at $199. When we replace your windshield, calibration is included in our $549 starting price for camera-equipped cars.
| Service | Our starting price |
|---|---|
| Camera calibration only | $199 |
| Windshield plus calibration | $549 |
Industry guides put standalone calibration at roughly $150 to $400. AAA's 2023 study found ADAS adds significantly to repair bills, with an average of about $1,440 for a windshield plus calibration. Prices last updated November 2026. See the cost guide for more.
What California law requires starting in 2027
Starting January 1, 2027, the California Motor Vehicle Glass Act (SB 988) sets rules for glass shops. According to the law as signed, before work a shop must tell you:
- Whether your vehicle has ADAS
- Whether the manufacturer calls for calibration after the glass work
- Whether the shop will do the calibration or refer it elsewhere
After calibration, the shop must give you written notice of the result. If the calibration failed, the shop must warn you not to rely on those systems. We already work this way.
What if a calibration fails?
We tell you in writing, and you should not rely on the driver assistance systems until the problem is fixed. Calibrations can fail because of a camera fault, a damaged bracket, a pre-existing code, wheel alignment, or conditions such as rain during a dynamic drive.
Next steps depend on the cause. We may retry under better conditions, check alignment, or recommend the dealer if the problem needs a part, software update or a dealer-only procedure.
Aftermarket glass and cameras
Most cameras calibrate correctly through quality aftermarket glass made to factory specs. A few vehicles are sensitive to small differences in glass optics or bracket position, and we'll tell you when OEM glass is the safer choice. Read OEM vs. aftermarket glass.
