DES MOINES, Iowa — A new Iowa law will allow veterans to have a designation on their driver's license or identification card.

The state Department of Transportation says the law was implemented Tuesday, several months ahead of schedule.

The law, signed by Gov. Terry Branstad last year, is a voluntary initiative designed to help veterans get discounts throughout the state without carrying official military documents.

Iowa law only allows the designation when a driver's license or identification card is first issued or renewed.
