Q. Do 1997 model autos need an emission sticker?

In Baton Rouge and other areas flagged for Air Quality violations in Louisiana all motorvehicles are required to pass an emissions inspection each year.

I've included a link to exemptions as provided by the Department of Public Safety's Office of Motor Vehicles (Louisiana's DMV) here:

The only age-based admission exclusion is for Show Cars that are 40 years old or older and not used primarily for every day driving.  Unfortunately, a vehicle manufactured in 1997 is not quite old enough to qualify.
