Are double/triple trailer endorsements required for South Dakota farmers within 150 miles of their farm?

Yes, drivers must have a CDL with endorsements to haul doubles/triple trailers in North Dakota.  The federal regulations which allow a farmer to operate within 150 miles of their farm without having a CDL do not restrict the pulling of doubles/triple trailers; however, the regulations do require that you operate in your state unless your state has a reciprocity agreement.

North Dakota and South Dakota have a reciprocity agreement which states that ND will recognize a SD farm vehicle operator; however, the SD operator has to abide by the same laws as ND farmers.  Therefore, a SD farm vehicle operator can haul doubles/triple trailers in SD, but they can’t do it in ND unless they are properly licensed.
