Iowa DOT authority for in-state hauling

Motor carrier permit. For-hire carriers hauling property inside Iowa need an Iowa DOT motor carrier permit, for household goods, liquids, liquid dairy or other freight.^[1] It costs $150, and bulk liquid carriers also attend a $200 safety seminar.^[2]
USDOT-IA number. Iowa is on FMCSA’s list of states that require USDOT numbers for intrastate carriers^[3], and Iowa-based for-hire intrastate carriers need a USDOT number with an “IA” suffix.^[4] Private intrastate farm operations are exempt from USDOT numbers and marking.^[5]
One office. Iowa DOT Motor Carrier Services in Ankeny handles intrastate authority, IRP, IFTA and oversize permits (515-237-3268).^[6] IFTA costs $10 plus $1 per decal set.^[7]

Iowa insurance requirements

Carrier	Minimum
10,000 lb and over, non-hazmat	$750,000
Under 10,000 lb	$300,000
Hazmat	$1,000,000 or $5,000,000

Iowa ties its limits to the federal ones^[1], and your insurer files a Form E. Cargo insurance is required, though no amount is set and it isn’t filed.^[6] Your filing must stay on file at all times, run at least a year, and give the DOT 30 days’ notice before cancellation.^[2] Oversize and overweight permits also require proof of at least $100,000/$200,000/$50,000 carried in the truck.^[8]

Iowa’s truck claim rules

$5 million cap. Noneconomic damages against commercial truck owners and operators are capped at $5 million, with exceptions such as alcohol or drugs, phone use, or speeding 15 mph or more over the limit.^[9]^[10]
Negligent hiring claims. If an employer admits the driver was acting within the scope of employment, a separate negligent hiring claim can be dismissed.^[9]

The cap doesn’t reduce what a serious crash can cost in medical bills and lost wages, so it’s not a reason to carry less than you need, but it does make Iowa claims more predictable.

Safety rules and drivers

Federal safety rules are adopted as of the October 1, 2025 edition.^[11] For drivers who stay in Iowa, the driver rules don’t apply at 26,000 lb or less unless the truck hauls placarded hazmat or carries more than 15 people.^[12]
Drivers from 18 for intrastate work, except placarded hazmat since July 1, 2025.^[13]
English proficiency law. From July 1, 2026, a driver without the required English proficiency faces a $1,000 fine or an out-of-service order, and a carrier that employs or engages that driver, including as an independent contractor, faces a $10,000 fine.^[14]

Weights, harvest loads and permits

Heavier off the Interstate. 80,000 lb on Interstates. Off the Interstate, with a properly licensed CDL driver, 6-axle trucks can run 90,000 lb, 7-axle trucks 96,000 lb, and 5-axle livestock trucks 86,000 lb.^[15]
Harvest proclamations. The governor issues harvest weight proclamations. The fall 2026 one, from September 10 to October 10, allows up to 90,000 lb without a permit for soybeans, corn, hay, straw, silage, stover, fertilizer, manure and distillers grains, but not on Interstates and not over posted limits.^[16]
Spring thaw. Local roads can be embargoed for up to 90 days a year once posted, and the fine is $2 per 100 lb over.^[17]
Permits. Single-trip oversize/overweight permits are $35 and annual permits $50 or $400. From January 1, 2027, fluid milk permits allow up to 136,000 lb on primary roads.^[18]

Taxes, tolls, speed and winter

Diesel tax is 32.5 cents a gallon, or 29.5 cents for B-20 and higher blends, from July 1, 2026.^[19]
Registration is $1,695 a year at 80,000 lb.^[20]
No tolls. Iowa DOT doesn’t collect tolls on any of its roads or bridges, so a text asking you to pay an Iowa toll is a scam.^[21]
Speed. Interstates allow 70 mph for all vehicles. From July 1, 2026, the default limit rose from 55 to 60 mph, and insurers may not use a driver’s first two minor speeding tickets in 12 months (10 mph or less over, in 34–61 mph zones) to set rates or to cancel or not renew.^[22]

Iowa freight

636.3 million tons of freight worth $509 billion moved in Iowa in 2023, and trucks carried 70.4% of the tonnage. The heaviest truck traffic is on I-80 between Iowa City and Davenport, I-35/80 through Des Moines and I-29/80 through Council Bluffs, and the state has 70 barge terminals.^[23] Iowa grew a nation-leading 2.772 billion bushels of corn in 2025^[24], had 25.3 million hogs on December 1, 2025^[25], and its 42 ethanol plants can make about 5 billion gallons a year.^[26]
