Most drivers barely notice it, yet it’s always within reach—a small plastic piece on the seat belt that quietly makes everyday driving easier.
This part is called a seat belt stop button, and its purpose is simple but important. It keeps the metal latch from sliding all the way down to the bottom when you unbuckle.
By holding the latch in place, it saves you from having to reach down between the seat and door every time you want to buckle up. That small convenience helps make fastening your seat belt quicker and more consistent.
