Can i make my homemade gocart street legal? (i live in louisianna?)?

i made the go cart frame myself and then i built up my go cart and put on a 18.5 hp lawnmower engine and it goes about 70 mph top speed i also have seat belts, turn signals in the front and back, brakes, brake lights, and headlights i put about 2 years of work into the go cart and i think it would be pretty cool to make it street legal so is there anyway i can do this?
Anybody have some (USEFUL) information?

Sure, make a whole bunch of them for crash testing till you meet the crash worthiness standards, meet the EPA emission requirements and you’ll be well on your way to being street legal.
