Driver Jack Harper, 25, had backed in at a truck stop in Corby, Northants to find a neatly pressed man approaching the end of his trailer.

Confused, the 25-year-old decided to film the situation, as the shameless piss-er pissed “without a care in the world”.

A video sent to The Sun, shows his footage beginning with the truck driver saying: “Hi mate. How you doing, alright? You’re just having a wee, are you?”

To which the man replies: “There are no toilets here.”

Shocked – Jack then responds: “So you’re just having a wee at the truck?” — to which the careless pee-er just says “yep”.

Distressed Jack then asks if the man can “make sure none of it goes on (the truck)”.

“I didn’t think he was going to have a wee. I thought he was going to get his thing out.

“I thought he was going to get changed or take his trousers off or something weirder.

“I was kind of relieved it was just a wee. The first thing in my mind was obviously that he was going to expose himself.

After finishing his piss…on the truck, the man gave a smile and wave before going on his merry little way.

“I don’t know why he couldn’t have gone in the bush or something. He just wanted to do it up my truck.”

“The funniest bit for me is that he’s probably someone’s grandad.”

Drivers – Has this ever happened to you?
