In the past drivers were taught to keep their hands at 10 o’clock and 2 o’clock. Now it is advised to hold the steering wheel differently depending on your steering technique
Hand-to-Hand Steering: When using this method, your left hand grasps the wheel between 7 and 8 o’clock, and your right hand between 4 and 5 o’clock.
Why YSK: these changes were caused by the inclusion of airbags and steering wheels becoming smaller
it is also advised to not wrap your thumb around the steering wheel but instead keep it flush to the face of the steering wheel, because if you are in an accident and the air bag is deployed your thumb being wrapped can cause injury

My friend who is an EMS paramedic told me about the thumb thing. Apparently lots of people either get broken thumbs or they’re lost entirely.
That is just because of people holding on to the wheel during a collision, doesnt matter the wheel holding position just if the thumb is wrapped around the wheel. If a crash is unavoidable letting go of the wheel and letting the belt work is the safest. In formula 1 when the drivers are unavoidably heading twards a wall youll see them cross their hands on their chest so their arms dont fly around during an accident.
Had a friend tell me about after i got into an auto accident years ago. I was gripping the sterring wheel 10 and 2 with my thumbs closed in. TYhat shit hurt like hell.
