A Washington State trooper got a 'huge' surprise when he spotted a driver in the carpool lane and a cardboard cutout of Donald Trump's head in their passenger seat.

Motorcycle Trooper Greg Ulrich pulled over the driver for a carpool lane violation after seeing the Donald's head attached to the headrest next to them.

A picture of the cutout was then posted on Twitter by State Patrol spokesman Rick Johnson, who said he couldn't help but laugh when he saw it.

Johnson, who has been on the force for 25 years, has seen plenty of people try to get away with driving in the carpool lane with mannequins or other cutouts.

But this was the first time he has ever seen the Donald make an appearance.

'Now we've seen it all,' Johnson told the Washington Post.

Users on Twitter were quick to crack jokes - and direct some insults at the Donald - after seeing the picture.

'Airbags don't count as passengers?' one asked, while another asked if he was 'too far to the left'.

Others said Ulrich should've let the driver, whose name was not released, off due to their creativity.

'Hilarious. Should have been let go with a warning for the comic value,' tweeted Eric Rothenberg.

And of course many joked that the writer was probably fined a 'YUGE' amount.

The citation came out to $136, which Johnson said is the normal fine for a carpool violation.
