@ What's wrong with this? You can be seriously inG *ed ifyou wear the shoulder belt under your arm. Ina crash, your body would move too forward, which would far increase the chance of head and neck injury. Also, the belt would apply too muchforce to the ribs, which aren't as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
