The classical method was to put the hands at 10:00 and 2:00. Some folks, particularly high performance drivers, would recommend 9:00 and 3:00. Now it’s common advice for 9 and 3 to stay out of the way of the airbags. I think it’s a more effective position anyway, although if it weren’t I would question the wisdom of the advice. Some emergency vehicle drivers are taught to grip even lower, but IMHO this is a poor tradeoff between steering wheel control and airbag safety. If you are in a collsion severe enough to deploy an airbag, a hand or arm injury might be the least of your worries.
