LDW in a car can refer to two different things:
-
Lane Departure Warning: LDW is a safety feature in cars that warns the driver if they are leaving a marked lane without using the indicator or if the vehicle is drifting out of its travel lane. LDW uses a camera located near the rearview mirror to detect lane lines and alert the driver if the vehicle is about to leave its lane. The system engages at speeds of 45 miles per hour and above on relatively straight or slightly curved roads.
-
Loss Damage Waiver: LDW is also an agreement with an auto rental company in which the renter is released from liability for physical damage to the vehicle in exchange for a fee. An LDW covers the renter throughout the rental period, providing 24/7 coverage even when they are not in the vehicle.
Therefore, the meaning of LDW in a car depends on the context in which it is used.
