Changing lanes can be one of the riskiest driving manoeuvres that a driver performs; lane change collisions account for about 4 to 10 percent of all automotive crashes. Research suggests that most involved drivers were unaware of the presence of the other vehicle. Most lane change collisions tend to result in glancing impacts (or sideswipes), posing a lower risk of injury for occupants. However, the cost to repair the involved vehicles is usually high. So, it is in the best interest of the smarter driver to try and avoid these collisions altogether. Drivers should be aware of their surroundings at all times and be ready to take defensive actions should it become necessary. It is always prudent to minimize the time spent driving in the blind spots of other vehicles and to signal and check your own blind spot before initiating a lane change of your own. Some new vehicles are even equipped with blind spot detection, lane departure warning and other technologies to mitigate these and other types of collisions.
