His carpool lane excuse was to die for.

A Nevada trooper pulled over a man he saw driving a minivan by himself Monday in a high-occupancy lane on Interstate 15 in Las Vegas.

“As I get up to the window, I see he’s wearing a polo shirt with a funeral home logo on it,” Trooper Travis Smaka said about the driver of the unmarked Chrysler Town & Country, the Reno Gazette Journal reported.

“He immediately tells me he’s got the remains of a person in the vehicle behind him, so I kind of glanced in the back and confirmed that,” Smaka said about a body bag strapped to a gurney.

“It kind of threw me off a little bit, and then he just made the funny remark, something along the lines of, ‘So he won’t count?’ ”

The trooper chuckled, but made no bones about it – telling the driver that deceased people don’t count before letting him off with a warning.

“It just threw me off. That was one of the more interesting responses I’ve gotten,” Smaka said, according to CNN.

To drive in the HOV lane, there needs to be more than one living person in the vehicle, so corpses — or mannequins – are not allowed.

“You must have a living, breathing human occupying the seats in the vehicle to be in compliance with HOV lane rules,” Trooper Jason Buratczuk said in a statement after the traffic stop.

“When you talk about high occupancy vehicle lanes, you’re talking about seats – so a person would need to occupy a seat to qualify,” he said. “This person was obviously a decedent and in the cargo area of the car, so they would not qualify for the HOV lane.”
