- Special Mobile Machinery (SMM)
Special Mobile Machinery (SMM) is any type of machinery that is pulled, hauled, or driven over a highway. It may be a vehicle or equipment that is not designed primarily for the transportation of persons or cargo over the public highways. This includes vehicles originally designed for the transportation of persons or cargo that have been redesigned by the addition of mounted equipment or machinery that are only incidentally operated on public highways.
Special Mobile Machinery includes vehicles commonly used in the construction, maintenance, and repairs of roadways, the drilling of wells, and the digging of ditches, backhoes, pumps, and excavators. To qualify for SMM, mounted equipment must be over 500 lbs. Any SMM is required to be registered as soon as it goes to work in a for-hire capacity in the State of Colorado. This can be done 3 different ways:
- Required if the SMM will be here longer than 11 months. Registration must be obtained at the Department of Motor Vehicles in the county where the SMM will be located.
Specific Ownership Tax Permit (SOT)
- This is a temporary permit for SMM that allows the machinery to work in Colorado for a minimum of 2 months but not longer than 11 months. Can be obtained at any Port of Entry.
Ad Valorem Taxation
- If the SMM is used solely on company property, the company may provide documentation that property taxes have been paid by presenting the Certificate of Ad Valorem Taxation.
If SMM equipment is contacted at a Port of Entry and there is no proof of registration or taxation it will be detained until proof is presented.
Access the SOT application form.
- Colorado Hazardous Materials (HAZMAT) Permit
A Colorado HAZMAT Permit is required for any vehicle carrying a placardable amount of hazardous material. If the vehicle is not permitted then a temporary HAZMAT Permit must be purchased from a Port of Entry for $25. The temporary permit is good for only one load and is invalid after the load reaches its destination, leaves the state, or 72 hours have passed, whichever comes first.
To apply for a Annual HAZMAT permit, visit CDOT.
- Passenger Mile Tax Permit
Colorado law requires payment of passenger mile tax when vehicles with a seating capacity of more than fourteen carry passengers for compensation, either intrastate or interstate. Vehicles that regularly travel in Colorado may set up a Passenger Mile Tax account for an annual permit. A vehicle carrying passengers that is registered in another state, and makes an occasional trip into Colorado, is allowed to pay the tax on a single trip basis. The fee shall be $25, or the actual tax, whichever is greater. The formula used to calculate the tax is $0.001 multiplied by number of passengers multiplied by number of Colorado miles. Temporary permits may be obtained at any Port of Entry.
Annual permits may be obtained online here.
