Lane departure warning (LDW)

This term is part of the following categories: safety, technology, sensors, and vehicle system. 

Version: 5.0, Release date: April 2023.

Definition: vehicle system that uses cameras or other inputs to detect impending lane exceedances by the vehicle and provide visual, auditory or haptic feedback to the human driver.
