Which of these positions of a three-point seat belt’s diagonal strap is incorrect and can increase injuries in a crash?

Correct answer

Resting it against the neck.

Resting it against the neck. The strap should pass across the middle of the collarbone, between shoulder and neck, and across the centre of the chest, snug and untwisted. Passing across the centre of the chest is part of correct positioning, not a reason to remove it from there. Do not wear it under the arm or behind the back. Position the lap strap low across the pelvis and follow vehicle instructions.
