In which situation will a fastened safety belt not function properly:
aWhen it is twisted.
bWhen its upper part is located below the neck.
cWhen it is tense.
Why?
A twisted belt does not lie flat against the body and concentrates pressure over a smaller area during a collision, reducing protection. The picture shows the belt near its buckle, but you must check the entire length of the webbing. The belt should be snug, and its upper section should run below the neck, across the shoulder and chest, not under the arm.
