According to authorities, a Taco Bell manager called police saying a truck was in the drive-thru lane with the engine revving and smoke coming out and that the driver may have fallen asleep.
When deputies arrived, they fond Falkner either passed or or snoozing, smelling of booze with his foot on the truck's accelerator, police said.
"I asked the driver if he knew he fell asleep with his foot on the gas pedal and he stated he didn't know," an arrest report said.
One of the deputies asked for Falkner's identification, and he replied "No," the report said. When asked again for his I.D., Falkner reached into his fast food bag and took out a taco.
A second deputy told Falkner they were asking for I.D., not a taco, and Falkner shrugged and began trying to eat the taco, the report said.
When Falkner finally got out of the truck, the deputies discovered that the truck was on fire, and quickly used extinguishers to douse the flames.
Falkner told the deputies he'd had "a beer," but breath tests measured his blood alcohol content at 0.227 and 0.225, about three times the legal Florida limit of 0.08.
Police arrested Falkner on a DUI charge. He was booked into jail and later released, police said. It was unknown whether he has an attorney.
