Safety rules for in-state trucks

Indiana incorporates 49 CFR Parts 40, 375, 380, 382-387, 390-393 and 395-398 by reference. Interstate and intrastate carriers must comply, subject to listed exceptions. (Ind. Code § 8-2.1-24-18(a))

Drivers aged 18 to 20 may drive a commercial motor vehicle within Indiana.
Hours-of-service and logbook rules do not apply to vehicles in intrastate construction service.
Private intrastate carriers, and intrastate carriers in construction service, are excused from the pre-trip and post-trip driver vehicle inspection report rules. Their insulin-treated drivers can get a state intrastate medical waiver.
For-hire intrastate carriers under the USDOT weight need a separate Indiana ID Number from DOR.

The federal lines, which apply in Indiana too

10,001 lb and interstate commerce: a USDOT number, a medical card, a driver qualification file, the hours-of-service rules and daily inspections (49 CFR 390.5).
26,001 lb: a CDL, for a single vehicle or a combination towing more than 10,000 lb (383.5). The CDL rules cover in-state driving as well (383.3), and drug and alcohol testing follows the CDL (382.103).

What we could not confirm

Indiana's statute lets in-state carriers register with the Department of Revenue and show an Indiana certification number instead, while the Department of Revenue says a USDOT number is needed. This page follows the Department of Revenue, which runs the program.
The state's sources draw the private-carrier line slightly differently: 'less than 26,000' in the Department of Revenue's FAQ, '26,000 or less' in the statute.
