# Summary of Edmunds and Moody County Speed Zone Rules The Department of Transportation is making technical updates to speed zone rules in Edmunds and Moody counties to improve clarity and safety. In Edmunds County, the changes extend a 45 mph zone on U.S. Highway 12 westward from Ipswich and remove an outdated speed zone on State Trunk Highway 134, while in Moody County, a speed limit on State Trunk Highway 34 near the Interstate 29 interchange is being reduced from 55 mph to 45 mph. Both rules are being standardized to measure distances to the nearest one-tenth of a mile and use clearer reference points (like street names instead of section lines), making speed zone signs more accurate and easier for drivers to understand.
