Here at Brian Robson Coachworks accident repair centre in St Albans, Hatfield, Welwyn Garden City Hertfordshire we offer a range of car repair services and can offer professional advice on all things automotive.

Many drivers don’t realise how much their car is “watching” the road. Advanced Driver Assistance Systems (ADAS) use cameras, radar, and sensors to support features like lane keeping, adaptive cruise control, blind-spot alerts, and emergency braking. These systems rely on accuracy. If a camera is even slightly out of position, it may misjudge distances or lane markings.

After an accident — or even after replacing a bumper, windscreen, mirror, or suspension component — the sensor’s alignment can change. The result? A car that still drives, but assistance features that may respond late, early, or not at all. Recalibration is the process of setting these systems back to the correct specification. Sometimes this is done in a workshop with specialist equipment and targets; sometimes it requires a road test under controlled conditions. The aim is to ensure the vehicle “sees” the world the way it did before.

Why does it matter? Because these systems are safety tools. If automatic braking triggers incorrectly, it can be frightening. If it fails to trigger when it should, it can be dangerous. Calibration helps restore confidence and keeps the vehicle performing as intended. If your car has warning lights or ADAS features behaving oddly after a repair, don’t ignore it. Getting it checked promptly at Brian Robson Coachworks accident repair centre in St Albans, Hatfield, Welwyn Garden City can make a real difference to safety. Even a small bumper knock can be enough to shift a sensor’s angle. Calibration isn’t a luxury add-on — it’s part of finishing the repair properly.
