The admissibility of evidence of the failure of an occupant of a passenger vehicle to use a safety belt in any civil action is governed by the following rules:
When a person making a claim for damages in a civil action was a child passenger, or when the person making a claim for damages in a civil action is making the claim on behalf of a child who was a passenger, in a passenger vehicle involved in the collision from which the damages suffered by that claimant child passenger are alleged to have arisen, evidence that said claimant child passenger was not wearing a safety belt at the time of the collision is not admissible to show any negligence of the claimant child passenger: Provided, That the evidence may be admissible, subject to the West Virginia Rules of Evidence, to show negligence of the driver of the passenger vehicle in which the claimant child was a passenger.
