If you are not wearing a seat belt and the car you are driving hits a fixed barrier, you will hit the steering wheel. this is because if you are not wearing a seat belt and the car you are driving hits a fixed barrier, you will hit the steering wheel. this is because the force of the collision has thrown you forward the steering wheel starts moving backward during the collision you continue moving forward as the car slows down.

Inertia.

Explanation:

If you are not wearing a seat belt and the car you are driving hits a fixed barrier, you will hit the steering wheel. This is because inertia.

When driver apply break then comes suddenly in rest position but our body still moving .That is why if we did not wear sheet belt we moves forward direction.

We know that from first law of Newton's ,it states that if an object is in rest or in uniform motion then it will be remain in the rest or in the motion util unless some external force will not apply.This is also called law of inertia.
