The weight exemption people reach for removes exactly two federal parts, and the audit is in neither
There is an Iowa exemption that looks, on its face, as though it would lift a light intrastate operation out of the whole federal corpus. It does not, and the rule that limits it is a definition rather than an exception — which is why the limit is easy to miss.
The reach clause is at 661 Iowa Admin. Code 22.1(2) paragraph a: operators of commercial vehicles as defined in the motor vehicle code are subject to the adopted federal regulations “unless exempted under Iowa Code section 321.449.” Section 321.449 carries a weight-based intrastate exemption, and stopping there produces the conclusion that a light intrastate carrier is outside everything.
Rule 22.2 then defines what the exemption reaches, and the answer is two parts. It provides that the phrase used in Iowa Code section 321.449(4) — the rules adopted for a driver of a commercial vehicle — means the regulations in 49 CFR Parts 391 and 395. The same rule fixes the scope of the neighbouring cross-references the same way: driver qualifications means Part 391, hours of service means Part 395, and the restrictions phrase used elsewhere in section 321.449 means Parts 391 and 395.
So the exemption removes driver qualification and hours of service, and nothing else. Part 385 is not in it. The new-entrant audit described in the previous section therefore survives for an intrastate Iowa carrier at any weight, because the exemption that would have removed it does not reach that far.
There is a second, independent reason the two do not meet, and it is structural rather than definitional. The statutory exemption is written on its face as applying to a driver engaged exclusively in intrastate commerce. Part 385 is a carrier-side part. A driver-side exemption and a carrier-side obligation are not in the same conversation, and the rule’s own definition and the statute’s own wording point the same way.
Other cutouts in the chapter were read and none of them touches the audit either. One exempts four classes of intrastate vehicle operation from the periodic inspection requirement only — implements of husbandry including nurse tanks, special mobile equipment, unregistered farm trailers, and vehicles registered for a gross weight of five tons or less used by retail dealers to deliver hazardous materials, fertilizers, petroleum products and pesticides to farm customers. Another relieves retail dealers delivering within a hundred-mile radius from certain parts while expressly keeping them subject to Parts 390, 392, 393, 396 and 397.
The equipment-side and driver-side consequences of section 321.449 are worked through in detail on our Iowa hot shot page, which is where that analysis belongs.
- The exemption in Iowa Code section 321.449 is scoped by rule to 49 CFR Parts 391 and 395.
- Driver qualifications means Part 391; hours of service means Part 395.
- Part 385 is not within the exemption, so the new-entrant audit survives at any weight.
- The statutory exemption is driver-side on its face; Part 385 is a carrier-side part.
- The chapter’s other cutouts reach periodic inspection and certain farm-delivery operations, not the audit.
- The driver and equipment consequences of section 321.449 are on the hot shot page.
