"I will probably blow a .12, but I'm hoping to be a .07," suspect Samuel Purtle told the deputy during the traffic stop.
Turns out, his blood alcohol content was .15, almost twice the legal limit, sheriff's office spokesman Chris Baldridge said in a news release.
The deputy saw Purtle driving his 1997 Acura at speeds of up to 100 mph on I-5 near Woodburn just before 7:30 a.m.
Purtle failed a sobriety test and was arrested on a DUII charge. He also received several traffic citations.
