Lane Departure Assist

Lane departure assist can refer to one of two systems:

  • A warning system that alerts you when you are about to exit your lane unexpectedly
  • A system that combines the warning feature with automatic steering to keep you inside your lane

A Lane Departure Warning (LDW) system can warn the driver of an unexpected lane departure through an audible or visual warning.

Sometimes it can also include a vibration in the seat in the direction of the threat (for example, if the car is drifting towards the left side of the lane then the left side of the seat will vibrate to alert you).

A Lane Keep(ing) Assist (LKA) system takes the above to the next level by actively keeping your car inside the lane if it detects that you are about to leave the lane unexpectedly.

Some systems will only take action if the car starts to drift towards the outside of the lane, while other systems actively work to keep the car centred in the lane at all times.

Advantages:

  • Provides assistance to drivers to avoid unexpected lane changes which are one of the main causes of accidents in the UAE

Disadvantages:

  • Can cause drivers to pay less attention on the road

Things to be aware of:

  • Lane departure assist systems only work on roads with clearly marked lanes
  • Make sure to check with the company you are buying the car off how ‘active’ its lane departure assist system is
  • The system determines an unexpected lane change based largely on whether or not you have switched on the indicator – so make sure to use your indicator to avoid the system trying to keep you in your lane when you don’t want it to!
  • Most systems can be switched off if desired
