HARRISON, WI (WTAQ) - One man is in critical condition following an ATV crash in Calumet County. 

It happened around 5:15 p.m. Sunday in the Town of Harrison.  

Sheriff's department says a 48-year-old man was sitting on the front of the ATV, his 18-year-old son was driving and a 15-year-old girl was sitting on the back.

The driver sped up, then slammed on the brakes. That caused his dad to fly off the ATV and onto a paved driveway.
