Any time a vehicle is involved in lane changing, there are a number of accompanying areas of danger.

When changing lanes on an expressway signal your intentions and do so well before the time.

On this page we look closer at these specific areas.

Dangers Lane Changing

Crossing Road

Opposite Side

  • From:

  •       Here we see a few situations of vehicles crossing from the        opposite side of the road into your lane.

  • To:

  •       This looks at the converse of the above. Namely where                vehicles intrude into your lane while crossing from your            side of the road to the opposite side.

Same Side

  • From:

  •       This scenario briefly looks at vehicles intruding into your            lane while entering from your side of the road.

  • To:

  •       Here vehicles are intruding into your lane while exiting              from your side of the road.


  • In:

  •       This is where a vehicle in your lane slows down in order to        cut into another lane.

  • Off:

  •       Forcing into your lane without leaving a gap.

Both Sides

  • A situation can easily arise where two vehicles enter the same lane from either side.

Not Looking

  • Examples of a basic failure to check before changing lanes.

What is lane change assist?

Lane Change Assist (LCA) is a driver assistance system designed to enhance safety by providing assistance during lane-changing maneuvers. It uses various sensors and technologies to monitor the vehicle's surroundings and alert the driver to potential hazards or unsafe conditions when changing lanes.

Here are key features and functions commonly associated with Lane Change Assist:

  • Blind Spot Monitoring (BSM): One of the primary functions of Lane Change Assist is to monitor the vehicle's blind spots. Blind Spot Monitoring systems use sensors, typically located on the side mirrors, to detect other vehicles in adjacent lanes that may not be visible in the driver's mirrors.

  • Visual or Audible Alerts: When a vehicle is detected in the blind spot, Lane Change Assist systems can provide visual or audible alerts to warn the driver. This helps the driver make more informed decisions before initiating a lane change.

  • Active Steering Intervention: In some advanced systems, Lane Change Assist may provide active steering intervention to help prevent unintentional lane departure or collisions. This can involve slight steering corrections to keep the vehicle within its lane or provide resistance if the driver attempts to change lanes when it is not safe.

  • Radar and Camera Technology: Lane Change Assist systems often use a combination of radar and camera technologies to monitor the surrounding traffic. Radar sensors can detect the speed and distance of nearby vehicles, while cameras help identify lane markings and potential obstacles.

  • Integration with Lane-Keeping Systems: Lane Change Assist may be integrated with lane-keeping assistance systems, which help the driver maintain their lane by providing gentle steering inputs. Together, these systems contribute to overall lane-keeping safety.

  • User Configurability: Some Lane Change Assist systems allow drivers to customize their preferences, such as the sensitivity of the alerts or whether active steering intervention is enabled.

Lane Change Assist is part of the broader category of Advanced Driver Assistance Systems (ADAS), which includes technologies designed to improve vehicle safety and reduce the likelihood of accidents. It's important for drivers to be familiar with the specific features and limitations of their vehicle's Lane Change Assist system and to use it as a supplementary aid while maintaining attentive and safe driving practices.
