Lane Keeping Support 

What is a lane keeping support system?

Using lane monitoring technology, lane keeping support (LKS) is an emerging safety technology that prevents drivers from unintentionally drifting out of their lanes.

How does it work?

LKS systems use information provided by sensors in a lane departure warning system (LDW) system to determine whether a vehicle is about to move out of its lane of travel. If so, LKS activates by correcting the steering, braking or accelerating one or more of the wheels, or a combination of both, resulting in the vehicle returning to its intended lane of travel.

What types of crashes does it prevent?

LKS systems provide a valuable safety benefit, and can help keep you and your passengers safe from crashes such as:

• Striking a car in an adjoining lane, which could either involve “sideswiping” a vehicle traveling in the same direction or hitting a vehicle traveling in the opposite direction; and
• A rollover, which often occurs when a vehicle leaves the road.

Does NHTSA recommend lane keeping support systems?

NHTSA has not set performance specifications for this technology. This technology may enhance the safety of the vehicle, and you may want to consider this technology when buying a new vehicle.
