What is the first step in putting on a three-point harness?

The first step in putting on a three-point harness is to loosen it. This action ensures that the harness is not too tight, making it easier to slip into the harness without feeling restricted or uncomfortable. Loosening the harness also allows for a proper fit to be achieved after the user is secured in place, which is critical for ensuring safety. Once the harness is on, the user can adjust the straps and secure it tightly for maximum protection. This sequence is vital for both ease of use and safety, as a properly adjusted harness can effectively restrain the occupant in the event of a sudden stop or collision.
