Medford Police say the driver of the van experienced a medical emergency or a seizure while driving.
The driver went over the sidewalk, through a black chain link fence, and landed on top of a small SUV and P.T. Cruiser.
No one at the scene was injured.
MPD says the driver was conscious at the scene but very confused.
“No one was injured, the fire department was able to stabilize his vehicle and then they escorted him out and he was transported to the local hospital,” said Medford Police Officer, Jason Becker.
The lane re-opened after about an hour and a half.
