Your cargo is precious. Lane Assist keeps it safe.

Discover the differences in Lane Assist safety features.

What is Lane Assist or Lane Departure Warning?

Lane Assist, sometimes called Lane Departure Warning, is a safety feature in most new vehicles that use forward-facing cameras to monitor lanes around your vehicle.

When a vehicle migrates out of the lane, the Lane Departure Warning system will alert the driver through a variety of methods that their vehicle has migrated to a different lane. The alerts may be audible or visual in nature, and may even include tactile warnings such as seat vibration.

Related safety features include:

  • Forward Collision Warning
  • Automatic Emergency Braking
  • Adaptive Cruise Control
  • Blind Spot Monitoring
  • Rear Cross-Traffic Alert

Read our guide below to understand what makes Lane Assist Systems a powerful safety feature, and what makes these safety features different between manufacturers.

Lane Keeping Assist FAQ

First, you may have questions about what Lane Assist is, and the difference between Lane Keeping Assist systems. Read our FAQ and then check out our recommended vehicles below.

Are all Lane Departure Warning Systems the same?

There are a few variations of the Lane Assist systems that you might encounter. Below are the different systems and what they mean.

Lane Departure Warning (LDW): Audible or visual warnings signal to the driver that their vehicle is approaching or may be crossing the lane markings.

Lane Keeping Assist (LKA): An automatic steering system, which may also include an automatic braking system, keeps the vehicle within its lane.

Road Departure Assist (RDA): An automatic steering system, which may also include an automatic braking system, keeps the vehicle on the roadway itself.

Lane Centering Assist (LCA): An automatic steering system, which may also include an automatic braking system, to keep the vehicle in the center of the lane.

Should I buy a car with Lane Assist?

According to ScienceDirect, Lane Assist can reduce single-vehicle lane departure crashes by 66% by the year 2045. Road crashes are one of the leading causes of death in the United States. 94% of crashes that result in fatalities are due to human error.

With Lane Assist, a type of driving automation aimed at preventing such crashes and automotive accidents, drivers have a safety net. Lane Departure Warning systems could reduce crashes by nearly 340,000 in the United States every year if available on all vehicles.

Lane Assist is more than just a warning system. From Forward-Collision Warning to other Lane Assist systems, your safety is of the utmost importance when you get behind the wheel. Text messages, billboards, stray animals, GPS systems, and children in the backseat all provide ample distractions for drivers. Lane Assist in its various flavors can help prevent distraction-related fatalities.

Many of these features are available on the standard trim levels of many modern vehicles, speaking greatly to their importance and ability to save lives on American roadways every year. Keep you, your teenage drivers, and your children safe with this helpful piece of modern technology.

Will Lane Assist work in all weather conditions?

Lane Assist and other sensor systems may not work in all weather conditions, but that doesn’t mean they aren’t still valuable. Consider the weather where to live and make a wish list of features when you are shopping for a new vehicle.

It’s impossible for sensor and camera systems on vehicles to work at optimum levels 100% of the time. Rain, snow, and other weather may delay or inhibit the sensors. Road conditions, such as potholes and asphalt cracks may also cause false alerts.

Similarly, on old roads or roads with less visible markings, Lane Assist may not be able to read lane markings. America’s infrastructure includes several different indicators of roadway edges in addition to the yellow stripe, such as raised dots on the pavement.
