Passing or overtaking a car>>>you are driving behind that car in the same lane. You signal a left lane change and move into the left lane, gain enough speed to get ahead of that car to the point it is visible in your inside rear view mirror. Signal right, switch back to original lane and resume driving at safe speed.
Cutting off a car, you change lanes quickly to get in front of a car in the other lane and continue driving in that new lane,
