A Canandaigua man was flown to the hospital after his four wheeler hit the side of a moving tractor trailer Friday.
This happened on Route 21 in Canandaigua just before 2 p.m. Deputies say Aaron Smreker, 20, didn't yield the right of way when he drove his four wheeler onto the highway.
He hit one of the back axles of the trailer and was thrown onto the pavement. Smreker was airlifted to Strong Hospital where he's listed in guarded condition.
While no tickets have been written yet, the deputies' investigation continues.
