Louisiana military members now only need to apply once for a 25% auto insurance discountBATON ROUGE — Louisiana military members can now apply just once for a 25 percent discount on their auto insurance instead of reapplying every year, the Louisiana Department of Insurance said. The discount applies to the liability portion of an auto insurance premium and is available to active-duty military personnel based in Louisiana, military reservists based in Louisiana and members of the Louisiana Army National Guard or Louisiana Air National Guard. Insurers may also voluntarily offer the discount to veterans with a VA disability rating of 50 percent or more and to retired members of the United States Armed Forces, National Guard, Louisiana Army National Guard and Louisiana Air National Guard. To apply, service members need to download the Louisiana Application Form for Military Discount, complete and sign it, then submit it to their auto insurance agent or insurance company along with the required eligibility documentation listed on the form. National Guard members must provide a letter from their commander on official unit letterhead verifying membership.
