Every vehicle used in any business in West Virginia for towing wrecked or disabled vehicles shall carry a safety chain at all times. No such towing vehicle may tow a wrecked or disabled vehicle unless a safety chain is securely in place coupling the towing vehicle to the vehicle being towed. For purposes of this section, safety chain means chain or cable of sufficient strength to keep the towing and towed vehicles connected in the event that the towing sling or other primary connection fails.
