North Carolina Practice Safety Belts & Restraints

The manual describes the proper path for the shoulder portion of a seat belt. Where should it lie on the body?

  1. A.
    Under the arm and across the ribs
  2. B.
    Behind the back with the lap belt worn alone
  3. C.
    Across the neck for the tightest hold
  4. D.
    Over the collarbone and across the breastbone Correct
The Why

The answer is "Over the collarbone and across the breastbone"

The manual routes the shoulder belt over the collarbone and across the breastbone, keeping it clear of the neck so a crash spreads the load across strong bone rather than the throat. The 'under the arm' answer reflects a habit drivers pick up when the belt feels tight against the neck; tucking the strap under the arm removes the upper-body restraint the belt is designed to provide.

Why the others miss

The traps in the wrong answers

A. Under the arm and across the ribs

Tucks the belt below the shoulder, removing the upper-body restraint the manual describes. This answer reflects the habit of moving the belt when it presses on the neck, trading protection for comfort.

B. Behind the back with the lap belt worn alone

Puts the shoulder strap behind the back, leaving the upper body unrestrained in a crash. This answer treats the shoulder strap as optional, but the manual routes it over the collarbone for a reason.

C. Across the neck for the tightest hold

Runs the belt across the throat, which can cause serious injury in a crash. This answer assumes tighter placement means safer, but the manual routes the belt away from the throat on purpose.
