When I first began driving, I hadn't driven very often and was quite inexperienced particularly in freeway driving. My friends convinced me to drive them all downtown on the freeway. Once the exit was approaching I became concerned that I wasn't in the correct lane to exit so began trying to shift into the lane to my right to make sure I could turn off onto the exit. Unfortunately, I checked my blind spot, but couldn't see all of my blindspot because one of my friend's heads were in the way obstructing my vision. I started to shift lanes as the truck in the lane to my right began to honk to alert me that I was about to side swipe him. Alarmed, I jerked the wheel to the left where I discovered another car. The cars around me must have sped up and out of the way, because after all the wheel-jerking my car began to fishtail left across all four or five lanes of traffic. Once I got to the left shoulder I got out of the car and refused to drive on the freeway any longer. Luckily I managed to not hit a single car, but it was not due any credit to my "skill" as a driver. I still cannot remember the entire incident clearly, but am now driving on the freeway regularly but am much more cautious regarding checking my blindspots prior to shifting lanes. I honestly do not have any idea how I managed to avoid hitting all cars in all lanes of traffic, but I wouldn't want to repeat that scenario again. Thank goodness I was very lucky. Endangering my own life is one thing, but endangering the lives of my friends, family, and those around me is something I wouldn't be able to bear if things had happened differently.
