For many people, a license plate is nothing more than a legal requirement and one of the formalities when acquiring a new car ...

There are certain plate types, such as “antique,” that do not follow this rule. Passenger, commercial and combination plates do follow the rule.

Please explain to me why some plates have dashes and some – with the same type of numbers – do not. For example: RI-123 and RI 123, some have spaces between the digits and some do not.
