Legal Question in Traffic Law in Missouri

It seems that you understand that a license tag is required. If you pull it without a tag you could suffer anything from a traffic ticket to being held personally responsible (and criminally liable) for any injuries or property damage from an accident while it is being pulled. If you want a more specific description of vulnarabilities, you should consult directly with an attorney in your area that practices both civil and criminal defense.
