Introduction: safety, compliance, and convenience
Advanced Driver Assistance Systems (ADAS) use windscreen-mounted cameras and other sensors to read lane markings, signs, and traffic. After windscreen work, those sensors must be realigned to the car’s body and geometry. That is what calibration does.
Calibration is required by manufacturers after a replacement and often after certain repairs. It protects road safety and MOT compliance. Learn more in ADAS calibration after windscreen replacement and Will a damaged windscreen mean an MOT fail? The environment matters too: a level, controlled space delivers accuracy. Fleet Motorglass offers mobile convenience across Bedfordshire, Buckinghamshire, and Hertfordshire, choosing mobile or workshop based on strict safety criteria.
How ADAS calibration works: static, dynamic, and dual
Static calibration uses targets positioned at set distances and heights in front of the vehicle. The floor must be level, the car at normal ride height, tyres correctly inflated, and lighting steady and glare-free. The camera then “re-learns” its reference points.
Dynamic calibration is a controlled road drive at speeds and conditions specified by the manufacturer to confirm sensor learning under real-world inputs. Many vehicles need both methods to complete the process. For more detail, see our frequently asked questions.
When mobile calibration on your driveway is safe and accurate
Mobile calibration suits many front-camera systems when the site and vehicle meet key checks. It cuts downtime and keeps fleets moving.
- Space: clear, straight area in front (typically 6–8 metres) and 2–3 metres around the car.
- Surface: flat, level ground; no slopes, drains, or soft verges.
- Lighting/weather: consistent daylight or controlled lighting; dry, low wind, minimal glare.
- Access: safe working area, power if needed, and minimal reflections or metal obstructions.
Vehicle pre-checks we complete on site:
- Correct glass specification fitted and camera bracket aligned
- Primer/adhesive used to spec and allowed to reach safe cure
- Tyre pressures set and vehicle at normal ride height
- Fault-code pre-scan to confirm the system is ready to learn
Pair this with our mobile car windscreen replacement for one efficient visit.
When a controlled workshop bay is required
Some scenarios rule out driveway work. We will advise a bay if safety, space, or equipment limits apply.
- Complex systems: multi-camera/radar/lidar setups, lane centring, or strict OEM light control
- Environment: limited space, uneven ground, strong reflections, heavy rain, or high wind
- Vehicle condition: incorrect ride height, wheel alignment issues, wrong tyre sizes, or active DTCs
Examples include HUD-equipped screens and advanced driver assistance suites. See our heated acoustic HUD windscreen repair guide for why exact glass spec and alignment matter.

Keeping safety systems within spec after a windscreen replacement
Our quality-assured process keeps ADAS within manufacturer tolerances:
- Diagnostic pre-scan and system health check
- Glass and parts to OEM-equivalent specification
- Correct primer and adhesive, with documented cure times
- Precise camera/sensor refit and alignment
- Static and/or dynamic calibration as specified by the OEM
- Controlled road test where required
- Final validation and post-scan
We only sign off once values sit within OEM tolerances. You receive a calibration report and certificate for your records and insurer.
People, tools, and standards you can trust
ATA-qualified technicians follow Thatcham and OEM methods, supported by up-to-date software and secure data handling. Our targets, lasers, levels, and rigs are regularly calibrated and verified.
Safety comes first. If conditions are not right on the day, we rearrange or move to a bay to protect accuracy and compliance.

Timeframes, pricing, and insurance
Typical mobile windscreen replacement plus ADAS calibration takes around half a day, including adhesive cure, depending on glass type and system complexity. Some dual calibrations or specific OEM procedures can take longer.
Costs vary with glass features (heated, acoustic, HUD), sensor count, and whether static, dynamic, or both are required. We process paperwork efficiently and coordinate with your insurer to minimise vehicle downtime.

How to spot miscalibration and what to do next
Watch for ADAS warning lights, “unavailable” messages, false alerts, or lane-keep behaviour that feels off. A pull in one direction, or recent tyre/suspension/alignment changes, can also affect readings.
Do not rely on affected features. Book a diagnostic check promptly. We prioritise safety-critical issues and can complete fault-finding and recalibration quickly to restore confidence.

FAQs: mobile vs workshop ADAS calibration
Do all cars need calibration after windscreen replacement?
If your car has ADAS sensors linked to the windscreen, yes—most modern vehicles do. It is mandated by manufacturers and vital for safety.
Is mobile calibration as accurate as workshop calibration?
Yes, when site conditions meet OEM requirements. If not, we switch to a controlled bay to guarantee accuracy.
What happens if it rains on the day?
We assess conditions. If weather compromises accuracy or safety, we reschedule or move to a covered or workshop location.

FAQs
Can you calibrate ADAS at my workplace car park?
Yes—if the ground is level, space is adequate, and lighting is consistent. We will confirm suitability during booking.
How long after fitting can you calibrate the camera?
Once the adhesive reaches safe drive-away cure per the manufacturer. We will advise timings when we book the job.
Will calibration affect my insurance or warranty?
No. We follow OEM procedures and provide a calibration certificate. This supports insurance and warranty records.
Do you support EVs and large vans?
Yes. Our mobile rigs and workshop bays handle most EVs, vans, and fleet vehicles, subject to space and system requirements.
What if a fault code prevents calibration?
We diagnose the cause first. We can resolve simple issues or refer for mechanical alignment or software updates as needed.
