All oversize loads entering the City of Ethan, located in Davison County, must conform to the requirements set by the South Dakota Department of Transportation.

In general, any vehicle over 12 feet in width, 14 feet in height, and within the Class 2 weight category (over 80,000 lbs but not exceeding 90,000 lbs) should obtain an oversize load permit from the Ethan Public Works Department.

Ethan, being a smaller municipality, adheres closely to state regulations but requires additional local permits for loads that may impact city infrastructure or traffic flow.

Escort vehicles are required in Ethan for loads exceeding 16 feet in width or 18 feet in height. The escort must be provided by a certified pilot car service familiar with Ethan's road network.

For loads that require a police escort, arrangements must be made through the Davison County Sheriff's Office at least 48 hours in advance. Fees for police escorts are $150 per hour, with a minimum of 2 hours.

To apply for an oversize load permit in Ethan, applicants can visit the Ethan Public Works Department's website or contact them directly at (605) 555-0123. Required documentation includes proof of insurance, detailed load specifications, and proposed route information.

Applicants must also provide a notice period of at least 72 hours before the move to allow for processing and route assessment.

Oversize loads are restricted from traveling during peak hours (7-9 am and 4-6 pm) on weekdays to minimize traffic disruptions.

Seasonal restrictions apply during the spring thaw (March 15 to April 15), where load restrictions may be imposed due to road conditions.

Loads are prohibited from using residential streets unless explicitly approved as part of the permit application.

The base permit fee for oversize loads in Ethan is $75. Additional fees are charged based on the complexity of the route: $25 for simple routes, $50 for moderate, and $100 for complex routes.
