There were some students in my Elder College class last week that were surprised to learn that it was no longer generally acceptable to hold the steering wheel with your hands in the 10 and 2 position. Who would have thought that how to hold your vehicle's steering wheel would change, or that it even mattered?
After sharing this idea with the class, the first question was "Why don't they tell us about this?" I countered with a question of my own, "When was the last time you read the owner's manual for your vehicle?"
The best theory today is for the left hand to be between 7 and 9, and the right hand to be between 3 and 5. This keeps your hands and arms out of the way if the airbag deploys and you don't end up having a fist fight with yourself in the event of a collision. Please note that these instructions call for both hands to be on the wheel.
