I grab my car keys and I go to the car and visually check the tires to make sure they are not low or flat . I open the door and get in the car then I lock the door . I put my seatbelt on and then I put the car key into the ignition and crank up the car . I place the car in reverse and look around to make sure there are no other cars or pedestrians in my path . I slightly press the gas pedal and back up , then I place my foot on the brakes and change gears to drive , then I put my foot on the gas pedal and drive forward and drive and follow the speed limit and road signs until I reach a stop sign , traffic light or signal . I pay attention to the traffic around me and stay in my traffic lane until I need to change lanes and make turns . I make sure that I use my left and right blinkers to let the traffic around me know that I am changing lanes or that I will make a turn . When I am ready to get to my destination , I turn my blinkers on , I slow the car down and make sure there are no pedestrians in my path , then I carefully drive to where I want to get to a parking spot , and put my foot on the brakes , then I place the car in park , and then I turn off the ignition and take the keys out of the ignition . I then make sure I turn off all lights in the car then lock and close the door . Question: When did they check the mirrors so they could see properly?
