Under vehicle inspection is when someone checks the under part of a car or any other vehicle to make sure it is working properly and safe to drive. This is really important because there are a lot of things under the car that can cause problems if they aren't working right.
When you go to get your car inspected, a person will use a special machine to lift the car up in the air so they can look underneath. They're looking for things like leaks, rust, and broken parts. They will also check to make sure the brakes, muffler, and suspension are in good condition.
Sometimes, they'll use a flashlight to get a better look at everything. They might also use special tools to measure things like tire tread and brake pad thickness.
Checking under a vehicle is really important because it helps keep cars and people safe on the road. Even though it might seem like a small thing, it can catch big problems before they turn into something dangerous.
