Yes, it is generally illegal for a person to ride in a car that is being towed on a tow truck bed. Most jurisdictions have laws prohibiting passengers from being in a vehicle while it is being transported, as it poses safety risks for both the passengers and other road users. Additionally, towing companies often have policies against allowing passengers for liability reasons. Always check local regulations for specific laws.
