Detailed Solution

The above statement is true.
When a running car stops suddenly, the passengers are jerked in the backward direction.
Newton's first law of motion or inertia states that "if a body is at rest or moving at constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless an external force is applied to it."
When a stationary car starts, the passengers feel a quick backward jerk. As the car starts and drives suddenly in the forward direction from a state of rest, the passengers feel a force applied to them because of the inertia. The inertia resists the forward motion.
