How reliable is lane-assist for preventing accidents?

On Behalf of | Nov 10, 2021 | Car Accidents |

Auto manufacturers are coming out with new exciting technology all the time. Over the last couple of decades, there have been many advancements to help drivers (and their passengers) stay safe on the road.

Blind spots can be difficult to deal with, no matter how large or small your vehicle. It can seem, especially in heavy traffic, that there is always someone just out of sight. Lane-assist systems offer a solution, but is it reliable?

Here’s what you should know about lane-assist features and when they are more (and less) reliable.

Intermittent vs. sustained

Not all lane-assist devices operate the entire time you are driving. Intermittent systems only activate for certain situations, such as when traveling over a specific speed. Knowing when an intermittent system is working can be challenging, so the interventions can feel confusing and out-of-place.

A sustained lane-assist system works all of the time. While this system is more predictable, it is easier to become more reliant on the system to correct your driving than to watch the other vehicles around you.


These systems tend to be reliable for helping you stay in your lane but typically will not differentiate between someone in your blind spot and moving out of your lane. When you use a lane-assist feature to support your driving, it is important to know what the alert means and how to respond.

No substitute for a human

When you purchase a vehicle with a lane-assist device, you get a tool, not a guarantee. Like many safety features, lane-assist is a tool to help you drive safer. It is not a substitute for looking for other vehicles. It is always essential to make sure the area around your car is safe.
