A semi-truck driver forgot a few major things when he took to the roads on the outskirts of Saskatoon last weekend: his wheels. 

At 8:30 pm we got a 911 call about a truck with no wheels on the trailer. Stopped on Grasswood Rd. The driver was charged with drive with major defect present, operate a vehicle with no safety inspection, and display unauthorized licence plate. #NotInCormanPark pic.twitter.com/yboPaca8Nm

Local police tweeted about a very unconventional call they responded to just outside of the Saskatchewan city on Sunday night. Officers arrived to find an 18 wheeler that was missing the wheels on its rear portion.

The trucks are meant to have a total of 10 wheels on their tractor and an additional eight wheels on the trailer they're pulling.

Trucker check list:

According to the CBC, this particular truck driver started his journey a few hours south in Regina, but was apparently missing four wheels before he even left.

He slowly lost the remaining wheels and continued on dragging the trailer along the road for some time.

The odd tractor-trailer tire explosion is nothing new, but a tractor-trailer driving without entire wheels just might be.

Wheels and a full axle were found in a ditch nearby. Despite the incident, Corman Park Police say all of the highways the wheel-less vehicle scraped across seem to be in okay shape.

How much experience do you need to count the appropriate number of wheels are present?

The driver has been charged by local and provincial authorities with operating with a major defect, unlawfully operating a vehicle without a valid Safety Inspection Service certificate, and an unrelated charge of displaying an unauthorized license plate.
