Okay kiddo, do you see that big round thing in front of the driver's seat in a car? That's called the steering wheel!
The steering wheel is super important because it helps the driver control which way the car goes. When the driver turns the steering wheel to the left or right, the car will start to turn in that direction.
The steering wheel is connected to something called the steering column, which moves a part called the steering gearbox. The gearbox then turns the wheels of the car, so that it can drive in the direction the driver wants.
It's really important for drivers to use the steering wheel correctly, especially when driving on the road with other cars and people. Drivers need to pay careful attention to the road and make sure they are turning the steering wheel the right amount so that they don't crash.
So, basically, the steering wheel helps the driver control which way the car goes and keep everyone on the road safe!
