Lane departure warning systems alert drivers when their vehicle leaves its lane, reducing accidents caused by inattentive driving. They use cameras or sensors to detect lane markers and sound an alarm if the car drifts. These systems are available on new cars and can be installed on existing vehicles.

A lane departure warning is a safety system in a car that alerts the driver when the car leaves its lane. In addition to being available for cars, lane departure warning systems can also be installed on trucks, buses, and other vehicles. The use of such systems can drastically reduce accidents caused by inattentive driving, making the road safer and reducing expenses related to car accidents, such as legal claims brought against inattentive drivers.

Lane departure warning systems work slightly differently on various car models. Most have cameras designed to see the markers used to delineate the lanes of a highway, and the cameras can distinguish between yellow and white markings. Other cars use different types of sensors. In all cases, when the sensor detects that a car appears to be leaving its lane, some type of alarm is sounded, such as a pop-up on the car’s display panel or a chime.

When a turn signal is enabled, indicating that the driver intends to turn or change lanes, lane departure warning will be deactivated as the driver clearly intends to leave the lane. In all other cases, the warning system will be active. Lane departure warnings can alert tired and sleepy drivers that they are drifting, perhaps because they are losing focus and it might be time to take a break, and they also warn fully alert drivers that they may not be paying enough attention to their position on the road.

Safety pioneers like Volvo were among the first to install lane departure warning systems, along with other sensor systems designed to increase driver safety by looking for problems with the driver, the car or the road. The introduction of such systems in the trucking industry has also had a profound impact, reducing accidents and making transportation much safer.

These systems are mostly available fully installed on new cars, although some companies offer systems that can be used to upgrade existing vehicles for safety. A car with a lane departure warning system may cost less to insure, since insurance companies typically lower rates for drivers with special safety features on their cars. This can lower the cost of the car over its lifetime, even if such a system increases the cost of a car at the time of purchase.
