The law of Inertia is basicaly that if an object is in motion, it will stay in motion unless a force is stopping it. It affects them because the object (person) is in motion, but nothing is stopping/restraining them.

Answer: Inertia affects a person who is not using a seatbelt during a crash when the vehicle stops the body will keep rolling as they don't have the seatbelt on to restrict them from going and perceiving a damage.

Explanation:

Inertia is the cause that somebody in vehicles needs to use seatbelts. A traveling vehicle has inertia, and so do the passengers inside it. When the motorist uses the brakes, an unbalanced energy is utilized to the vehicle. Commonly, the rear of the position involves an unbalanced force—resistance—which reduces the passengers falling as the car decelerates.
