A state trooper caught a driver going 125 mph in Des Moines' east mixmaster this week, resulting in a $465 ticket, Iowa State Patrol said.

The State Patrol posted about the speedy driver on Facebook, noting that 125 mph is 60 miles over the posted speed limit for the east mixmaster.

The driver was cited and fined $465, said Trooper Alex Dinkla, spokesman for the State Patrol.

"Speed is still the leading cause of collisions and fatalities in Iowa. Slowing down and driving careful start with YOU – the driver!!," the patrol's Facebook post said.

There had been 169 deaths on Iowa roads so far this year as of Wednesday. Many of those fatal crashes are attributed to high speed, the State Patrol said.
