In which situation will a fastened safety belt not function properly:
Show the correct answer
Correct answer
A. When it is twisted.
Explanation
A seat belt works properly only when it lies flat against the body: the upper part runs across the middle of the collarbone and the chest, and the lower part runs low across the hips. A twisted belt has a smaller contact area and, in a collision, cuts into the body like a rope instead of spreading the forces over a wide strap - this may cause serious injuries. That is why the correct answer is A.
Answer B describes the correct position: the upper part of the belt should run below the neck, not over it. Answer C is also wrong, because a tight belt that lies close to the body is exactly what you want - a loose belt lets the body build up speed before the strap starts to stop it. Before driving, check that the strap is not twisted and that there is no thick jacket under it.
