Trump mocked for truck toot

In perhaps the most bizarre stunt pulled yet by newly elected US President Donald Trump, video has emerged of The Don climbing into the cab of a truck where he pulls the horn - much to the delight of onlookers.

A photographer caught the President pretending he was driving the truck - a photo that has been quickly mocked by many.

Social Media responded, many comparing his antics to being an extra on Mad Max.

At the time President Trump was meeting CEOs from the American trucking community at the White House. 

Watch the video.
