Iowa Rest Area & Parking Rules
Twenty-four hours, and you can stay longer for rest, bad weather, or reasonable need. Iowa has no rest-area statute, so the posted sign controls. Sleeping in your cab is fine, and that 24-hour window easily covers a 10-hour reset. 'Iowa Trucks Park Here' shows real-time space counts at 24 public rest areas on the Iowa 511 map; I-80 fills early. This is a reference, not legal advice.

Limits, truck parking, and HOS rest
- Time limit: 24 hours; longer allowed for rest, poor weather, or reasonable need
- MAASTO TPIMS state. 'Iowa Trucks Park Here' (live since January 2019) shows real-time availability at 41 facilities, including 24 public rest areas on I-80, I-29, I-35, I-380, and I-235, viewable on the Iowa 511 rest-area layer. I-80 spaces fill early.
- HOS: not addressed in statute, because Iowa has no rest-area statute, but the posted 24-hour limit plus the rest/weather/reasonable-need exception easily covers a 10-hour reset. Dual lens: the rule is the sign, not a code section; sleeping in your vehicle is fine. Iowa DOT actively supports truck parking (Trucks Park Here / Rest Assured). Welcome centers follow the same approach. Weigh stations are not overnight rest stops. Rest Area Administrator: david.bollenbaugh@iowadot.us.
What overstaying costs
No verified dollar figure. Staying past 24 hours without a rest, weather, or reasonable-need justification gets a citation and/or tow.
