Tennessee Permit Practice Test

A child in a child passenger restraint system (car seat) should follow specified guidelines to ensure their safety. Choice A is correct because infants weighing less than 20 pounds and under 1 year old are safest when facing the rear of the car. This is because in the event of a crash, the rear-facing position offers better support for the infant's head, neck, and spine.

Choice B is also correct as children aged one through three years old and weighing more than 20 pounds should face forward in their car seat. This allows for proper protection and is appropriate for their age and weight.

Therefore, the correct answer is C, as both options A and B are in line with recommended safety guidelines for children in car seats.
