Thirty-nine-year-old Jeffrey Laub told a judge Monday that he ate something that upset his stomach and was racing to get to a rest area in Logan Canyon.
A local newspaper reports that 1st District Judge Thomas Willmore called the explanation "one of the worst stories" he ever heard.
The judge pointed out that Laub passed several outhouses while he led a Utah Highway Patrol trooper on a chase last spring that reached 111 mph.
Laub, who's from Garden City, pleaded guilty in August to failure to stop and impaired driving.
