South Dakota Rest Area & Parking Rules

Sleeping overnight in South Dakota

You get 3 hours, or 10 hours if you are a CMV driver under federal hours-of-service rules (SDCL 31-7-17). South Dakota writes the HOS carve-out right into the statute. Sleep in your cab and you are fine; set up an RV and it is 'camping,' a petty offense (SDCL 31-7-18) handled as a fine-only civil violation. I-90 and I-29 spaces are usually open. This is a reference, not legal advice.

Limits, truck parking, and HOS rest

• Time limit: 3 hours; 10 hours for a commercial driver subject to 49 CFR Part 395
• Truck spaces on I-90 and I-29 are generally available. No real-time TPIMS. SDDOT runs SD511 (sd511.org) for travel info and operates Ports of Entry. Sleeping in the cab is fine; RV camping counts as camping and is barred. South Dakota is not a MAASTO TPIMS state.
• HOS: yes, explicit. The statute writes the carve-out in, giving a CMV driver under 49 CFR 395 up to 10 continuous hours while everyone else gets 3 (SDCL 31-7-17). Dual lens: sleep in your cab and you are fine; set up an RV and it is 'camping,' a petty offense. Weigh stations and Ports of Entry are not overnight rest stops. Welcome centers follow the rest-area rules. Fine note: a South Dakota petty offense is not a misdemeanor, so the $500 Class 2 cap in SDCL 22-6-2 does not apply; camping is a fine-only civil action under chapter 23-1A (SDCL 22-6-7).

What overstaying costs

Camping at an interstate rest area is a petty offense (SDCL 31-7-18), a fine-only violation prosecuted as a civil action under chapter 23-1A (SDCL 22-6-7), and you can be billed for any damage you cause (SDCL 31-7-15). Overstaying the 10-hour truck limit draws a move-along or citation.
