Intrastate for-hire permit

Iowa Code 325A.4, Iowa DOT intrastate authority manual

Insureon reports that Iowa businesses buying commercial auto through it pay an average of about $151 a month, or $1,817 a year. It calls this limited data, mostly from businesses with fewer than five employees, so it mainly reflects pickups, vans and cars. A for-hire truck of 10,000 pounds or more must carry $750,000 in liability under Iowa DOT rules and costs far more to insure. For-hire carriers also pay the Iowa DOT a $150 permit fee, and another $150 to reinstate after a lapse.

Iowa

What’s different in Iowa

20/40/15 is the floor, and it is low for a work vehicle

Iowa Code 321A.1 sets the minimum at $20,000 for one person’s injuries, $40,000 per accident and $15,000 for property damage, for business and personal vehicles alike. A crash involving a newer vehicle or a storefront can pass $15,000 quickly, and the rest falls on your business.

UM and UIM are on the policy unless you reject them in writing

Iowa Code 516A.1 requires uninsured, underinsured and hit-and-run cover on every policy for a vehicle registered or garaged in Iowa, at limits of at least $20,000 and $40,000. You can reject it only by signing a rejection on a separate sheet, and that rejection carries to renewals with the same insurer.

No proof can cost you the plates or the vehicle

Under Iowa Code 321.20B an officer can issue a warning, a citation, pull the plates and registration or impound the vehicle. Section 805.8A sets the fine at $325, or $645 when the violation is tied to a crash. An impounded vehicle left unclaimed for 30 days can be treated as abandoned.

For-hire trucks need a Form E on file with the Iowa DOT

Iowa Code 325A.6 holds intrastate for-hire carriers to the federal limits in 49 CFR 387. Under Iowa DOT rule 761-524.7 the insurer files proof electronically and gives 30 days’ notice before cancelling. If the filing lapses, the permit is suspended until a new Form E and a $150 reinstatement fee arrive.

Pain and suffering awards are capped at $5 million for CDL vehicles

Iowa Code 668.15A, signed in 2023, limits noneconomic damages to $5 million per plaintiff in suits over a commercial vehicle that requires a CDL. Medical bills and lost wages sit outside the cap and passenger carriers are excluded, so one crash can still exceed a $1 million policy.

Fault decides whether the other side can collect

Under Iowa Code 668.3, a claimant whose fault is greater than the combined fault of the defendants recovers nothing; anyone else has damages cut by their own share. Dash cameras and prompt crash reports help show who was at fault.

Coverage

Coverage Iowa businesses need

Commercial auto liability

Motor truck cargo

Hired and non-owned auto

Covers your business when employees drive their own, rented or leased vehicles for work.

Umbrella or excess

Adds limits above your auto policy when a contract asks for more than your primary limit, or when a CDL truck’s exposure outruns it.

Rules

Pay less

How to lower the cost

Keep your Form E continuous: the insurer must give the Iowa DOT 30 days’ notice before cancelling, so act on any notice before the permit is suspended and you owe a $150 reinstatement fee.
Check whether Iowa’s cargo exemption covers your loads, such as gravel, coal or scrap iron, before buying cargo cover the state does not require; confirm your customers’ contracts first.
Hire drivers with clean records and review them every year, since Insureon lists employee driving records and claims history among the main rating factors.
Raise physical damage deductibles on older vehicles you could afford to repair yourself.
Keep an insurance card, paper or on a phone, in every vehicle so a stop does not end with pulled plates.
Compare several quotes at renewal; Florin is an independent broker that compares options from several insurers.

Commercial auto insurance in Iowa: questions

The scheduled fine is $325, or $645 if connected to a crash, under Iowa Code 805.8A. The officer can also pull the plates or impound the vehicle.

Carriers that haul property or passengers for pay within Iowa under an Iowa DOT permit or certificate. The insurer files it electronically, and the permit is suspended if it lapses.

Does Iowa require cargo insurance?

Do Iowa intrastate trucks need a USDOT number?

Can I reject uninsured motorist coverage in Iowa?

Yes, but only with a signed written rejection on a separate sheet, under Iowa Code 516A.1. The rejection then carries to renewals with the same insurer.

Does Iowa cap damages in truck crash lawsuits?

Iowa Code 668.15A caps noneconomic damages at $5 million per plaintiff when the vehicle requires a CDL. Economic losses such as medical bills are not capped, and passenger carriers are excluded.
