What is lane centering?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Lane centering uses the forward camera behind the windshield to actively hold the car near the middle of the lane, applying continuous light steering. It is a step beyond lane keeping assist, which only nudges you back when you drift. The driver keeps hands on the wheel and remains responsible. It is not self-driving.
Lane centering vs lane keeping assist
Lane keeping assist
- Steers only when you drift toward a line.
- Reactive — nudges you back.
- Hands stay on the wheel.
Lane centering
- Holds the car near the middle continuously.
- Proactive — applies steady steering.
- Hands stay on the wheel.
Both use the forward camera and both leave the driver in charge. Lane centering just steers more of the time. See our guide on how lane keeping assist works.
Common myths about lane centering
Lane centering is self-driving.
It is not. The system holds the car near the lane center, but the driver keeps hands on the wheel, watches the road, and stays responsible for the car.
Lane centering and lane keeping assist are the same.
They differ. Lane keeping assist reacts when you drift; lane centering steers continuously to hold the middle. Some vehicles bundle both.
How lane centering uses the camera
The forward camera behind the windshield reads both lane lines and works out where the car sits between them. The system then applies continuous, light steering torque through the electric power steering to keep the car near the center. It needs clear lines, a set minimum speed, and the driver’s hands on the wheel, and it warns you if you let go for too long.
Because the camera behind the glass does the work, a windshield replacement shifts its aim and the camera has to be recalibrated. Skyview handles that during the replacement — static calibration takes 30 to 60 minutes, dynamic adds a 15 to 30 minute drive, and some vehicles need both. The work typically costs $95 to $300 with a pre-scan and post-scan, and if the car drifts or the lane-keeping behaves oddly after Skyview calibrates, Skyview comes back and redoes it.
