IDAHO FALLS, Idaho (AP) -- Speed limits have increased by 20 miles-per-hour on three state highways in Idaho.
KIDK-TV reports 50 mph signs are being replaced with 70 mph signs on U.S. 20, Idaho 22 and Idaho 28 after the Idaho Transportation Department determined that most drivers go between 70 and 80 mph on those roads.
The ITD says increasing speed limits can result in fewer crashes.
Part of Idaho 28 south of Leadore will be also be increased from 45 to 55 mph.
Current speed limits remain in effect until the new signs are installed.
