What Is the Honda Road Departure Mitigation System (RDM)?

  • Honda Road Departure Mitigation System Slider

As part of the Honda Sensing® suite of driver-assist technologies, the Road Departure Mitigation System (RDM) is designed to enhance driver confidence by helping to keep your vehicle in its lane and on the road at all times. If you begin crossing into another lane without signaling RDM can provide steering input to help get you back in your lane. Furthermore, if RDM detects your vehicle is leaving the road it can apply the brakes when steering assistance isn’t enough. Although Road Departure Mitigation works automatically, Vern Eide Honda in Sioux Falls is here to help you with the system’s settings and functionality.

How does the Honda Road Departure Mitigation System work?

The Road Departure Mitigation System uses a windshield-mounted camera to detect lane and road markings. If RDM recognizes your vehicle unintentionally leaving its lane, a visual alert will appear in the instrument panel and your steering wheel will vibrate. The electric power steering will also prevent your vehicle from drifting and if the system determines your vehicle is drifting off the road altogether it will apply the brakes.

For RDM to function properly, your vehicle must be traveling between 45 and 90 MPH on a straight or slightly curvy road. Additionally, ensure the brakes, windshield wipers, or turn signals are being used.

What is the difference between Road Departure Mitigation and Lane Keeping Assist? Vern Eide Honda has put together some quick tips to show you how these Honda Sensing features differ:

  • LKAS keeps you centered in a lane.
  • RDM notifies you if you drift out of a lane or off the road.
  • LKAS must be turned on manually.
  • RDM can be kept on all the time.
    • RDM has a dedicated toggle switch that maintains its setting regardless of the car having been shut off. You can adjust its sensitivity in the settings menus.
    • LKAS has a steering wheel switch that must be re-enabled each time the car is started.
