16 may be too young to serve in the military, and there may be no draft coming (according to Bush, at least) but that hasn't stopped Louisiana from thinking ahead to when there may be a draft: In order to get a driver's license, those as young as 16 must register with the Selective Service

There may be no "plans" for a national military draft, but that hasn't kept Louisiana from registering teenagers too young to serve in case conditions change. During the recently concluded presidential campaigns, the major candidates repeatedly said they had no plans to resume compulsory military service.

Their promises were not reassuring, however, to Larry Chevalier of Glenmora who was alarmed when his 16-year-old son Nathan had to register with the Selective Service System in order to get a driver's license.

When was this law enacted? In 2003:

the Legislature passed Act 373 in the 2003 session dictating that all males aged 15 up to 18 seeking a first-time driver's license or an OMV identification card must register with Selective Service.
