1. Motor Vehicle Use Map (MVUM) Questions (
/
)
I’ve heard a lot of talk about MVUM’s. What are they?
The United States Forest Service uses a system of “Designated Routes” to manage OHV use. These Motor Vehicle Use Maps (or MVUMs) are the official record of what routes are open on National Forests and Grasslands.
Where can I find Motor Vehicle Use Maps (MVUM’s)?
You can find current MVUMs available for free download here: http://staythetrail.org/mvum/index.php
Printed MVUMs are also available for free at Forest Service field offices. A list of these offices are available at http://staythetrail.org/wheretogo/nationalforests.php
What information is on an MVUM?
You will be able to find information about what Forest Service routes are open, and also what type of vehicle they are open to. Each road and trail is identified by whether it is a road open to highway-legal vehicles, all vehicles, vehicles 50" or less in width, and singletrack for dirtbike use. The maps also may include information on roads managed by other agencies (county, city, etc) as well as information on dispersed camping.
Where can I camp along these routes?
On the MVUM, you will see information on designated campsites and dispersed camping. You will have to pay attention to what each individual MVUM says about camping, as they vary from one district to another. When dispersed camping, please use existing fire rings if you are going to have a fire and camp 200 feet from water bodies. More information on camping guidelines can be found at http://www.treadlightly.org
Is parking along a designated route considered "off-trail"?
No. As a general rule, park as close to the route as you can without blocking the trail, if you cannot find a wide spot that is appropriate to stop at. Please don't park on fragile vegetation (cryptobiotic soils, alpine tundra, etc) and don't run over trees and shrubs to find a spot to park. Many ranger districts are directing enthusiasts to stay within one vehicle length of the route. The same standards should be followed when recreating on BLM lands.
2. Vehicle and OHV Registration/Permit Questions (/)
What types of vehicles have to purchase an OHV Registration/Permit?
All off-highway vehicles operated in the State of Colorado must obtain a registration or permit from the OHV Registration Program administered by Colorado State Parks, including those owned and operated by non-residents. Registration information available at http://parks.state.co.us/OHVsandSnowmobiles/OHVProgram/
Is my ATV legal to ride on the street?
In general, no. There are a few local jurisdictions that allow OHV use on certain roads to connect trails to staging areas or gas stations, but this is not the norm. We recommend contacting the local Sherriff's Department for additional information. Contact information for each county can be found here: http://www.csoc.org/counties.asp
I have my ATV / Side-by-Side licensed for street use in my home state. Can I ride it on public roads in Colorado?
The short answer to this is no. Each state does have the authority to decide what types of vehicles to allow on public roads, and Colorado does not recognize ATVs and Side-by-Sides as vehicles appropriate for licensing and street use. There are a few local jurisdictions that allow OHV use on certain roads to connect trails to staging areas or gas stations, but this is not the norm. We recommend contacting the local Sheriff's Department for additional information. Contact information for each county can be found here http://www.csoc.org/counties.asp
When is the OHV Registration/Permit period?
The OHV Registration/Permit year lasts from April 1st to March 31st.
I live in another State but will be visiting Colorado to ride. Is the OHV Registration from my home state valid in Colorado?
No. You will need to obtain an Out-of-State OHV Permit to ride your OHV in Colorado. Please visit http://parks.state.co.us/OHVsandSnowmobiles/OHVProgram/ for additional information.
I live in Colorado but am going to ride in Utah, is my Colorado OHV registration valid there?
No. You will need to purchase an Out-of-State OHV Permit in Utah, and any additional States you visit to ride. However, the need for registration or permitting your OHV in both states has a positive side. The state OHV money returns out to the trails, but only in THAT state. So, trail work that is being done through the OHV grants in Colorado are not being funded by Utah riders even though they may ride here... unless they purchase an Out-of-State OHV Permit in Colorado, and vice versa. That is why it is actually not a "bad" thing to have to register or permit your OHV in both places. We do realize that means that vacations can get expensive, and we unfortunately can't offer any advice for that.
3. Where can I go? (/)
I'm looking for maps on where to ride. Can I get them from Stay The Trail?
Yes. We have free downloadable maps at http://staythetrail.org/maps/index.php
How do I know if my favorite trail/road is open?
Check the Motor Vehicle Use Map (MVUM) for Forest Service routes, and official BLM travel management maps. The MVUM's can change yearly, so stay tuned to our MVUM page for updates: http://www.staythetrail.org/mvum
Information on Seasonal Closures can be found here: http://staythetrail.org/wheretogo/closureinfo.php
If you are still not sure, contact the Agency(s) responsible for that route. Field office listings can be found here:
USDA Forest Service - http://staythetrail.org/wheretogo/nationalforests.php
Bureau of Land Management - http://staythetrail.org/wheretogo/blmoffices.php
What routes can I use my dirtbike on?
Any route designated for motorized use that is single-track or wider, such as ATV/50" and 4x4 routes. Keep in mind that most 4x4 routes do not permit unlicensed dirtbikes to be ridden on them. Use your Travel Management Maps http://staythetrail.org/wheretogo/index.php or follow the signs http://staythetrail.org/etiquette/signs.php to determine where you are permitted to ride.
What routes can I use my ATV on?
You can ride your ATV on designated 50" and 4x4 routes. ATVs that are over 50" in width are allowed on most 4x4 routes and authorized OHV-open roads. Keep in mind that most 4x4 routes do not permit ATVs to be ridden on them. Use your Travel Management Maps http://staythetrail.org/wheretogo/index.php or follow the signs http://staythetrail.org/etiquette/signs.php to determine where you are permitted to ride.
What routes can I use my Side-by-Side (UTV) on?
You can use your Side-by-Side on 4x4 roads. The vast majority of Side-by-Sides are wider than the 50" rule, and therefore, are limited to 4x4 routes and authorized OHV-open roads. Use your Travel Management Maps http://staythetrail.org/wheretogo/index.php or follow the signs http://staythetrail.org/etiquette/signs.php to determine where you are permitted to ride.
4. Sound Law Questions (/)
What is the new sound law?
Passed in 2008, and going into enforcement on July 1, 2010 the new Sound Law sets new noise standards for OHV exhaust emissions. Up until July 1, 2010 Stay The Trail and various land management agencies will be providing free sound testing at appropriate locations. This new law is the result of a cooperative effort aimed at ensuring continued access for OHVs on our public lands.
What are the sound limits?
The new law establishes limits at:
96dB(a) if manufactured after January 1, 1998
99dB(a) if manufactured before January 1, 1998
What is the test for sound emissions?
OHVs will be tested using the SAE J 1287 stationary 20" pipe test.
Where can I get tested?
Check the Stay The Trail calendar for trailer locations. At trailhead events and other appropriate areas, we can offer free sound testing. Land management agencies will also have staff out providing testing at certain locations up until the law goes into effect.
How does this affect used machines being sold at dealerships or through private parties?
The responsibility for making sure that an OHV is within the limits established by this law will rest on the purchaser. That means that you can still buy a used OHV that doesn't meet the standards, but before use on public lands, the OHV will have to be modified appropriately.
How does this affect new machines being sold at dealerships?
The new law prohibits the sale of new OHVs over the 96dB(a) limit, unless that machine is designed for, and used in a closed-course competition facility.
Does this mean that I don't have to worry about sound limits when riding my motocross bike on public lands?
No. Any OHV that is intended for use in closed-course competition facilities, but is used on public lands, may require modifications for sound and spark arrestor standards when used outside of a closed-course facility.
5. Spark Arrester Questions (/)
Do I need a spark arrester to ride my OHV on public lands?
Yes. Colorado Law requires the use of a spark arrester on OHVs on public land.
From the Colorado State Parks OHV Program website: http://parks.state.co.us/OHVsandSnowmobiles/OHVProgram/
Except as provided in section 33-14.5-109 C.R.S., no person shall operate an off-highway vehicle upon public land in this state unless the off-highway vehicle is equipped with a spark arrester in good working order which has been approved by the U.S. Forest Service. A spark arrester is a device which traps or pulverizes exhaust particles as they are expelled from an internal combustion engine exhaust system and is effective in reducing exhaust sparks and protecting against exhaust spark fires. Spark arresters will trap or pulverize exhaust carbon particles to a size below 0.023 inch in diameter, as they are expelled from an exhaust system. Most spark arresters generally perform in the high 90% spark arresting effectiveness range.
Wait, you mean my custom buggy or sand-rail has to have a spark arrester?
Yes. If you removed the exhaust system from the original vehicle, you also removed the spark-arresting abilities for that engine. You will need to have a FS-approved arrester on there.
Who decides if an exhaust has a Forest Service approved spark arrester?
The USDA Forest Service has a testing center that certifies spark arresters that are available. The list of certified spark arresters can be found at http://www.fs.fed.us/fire/prev_ed/spark/sag-index.html
Do I have to have a spark arrester on private land?
Similar to the sound regulations, spark arresters are only required on public lands. However, it is recommended to use an approved spark arrester wherever you ride.
Where can I get more information?
More information on the USDA Forest Service Spark Arrester regulations can be found here: http://www.fs.fed.us/r5/sanbernardino/recreation/ohv/sparkarrester.shtml
6. Kids and OHV's (/)
How old must my child be to ride an OHV in Colorado?
On Forest Service or BLM roads and trails - There is no age restriction other than the recommendation of the manufacturer. It is EXTREMELY important that the operator can reach all the controls for the machine while seated comfortably on the machine.
On designated county or city roads - No operators under the age of ten. Operators over the age of ten must have a) a valid drivers license, or b) be under the direct supervision (at minimum visual) of a licensed adult. Some counties may have other restrictions (See the Alpine Loop questions below).
Is there a helmet law in Colorado?
For adults, there is not. However, for minors (under the age of 18), they are required to wear a helmet while operating or riding as a passenger.
Can I carry my children on my ATV?
While there is no law prohibiting children (or adults) from riding as passengers on an ATV, we highly discourage having passengers of any age on machines that were not specifically designed for such use.
Where can I get OHV training for my children and/or myself?
The Motorcycle Safety Foundation and Specialty Vehicle Institute of America have established schools to train riders of all ages:
DirtBike School
2 Jenner, Suite 150
Irvine, CA 92618
ATV Safety Institute
2 Jenner, Suite 150
Irvine, CA 92618

8. Other Questions (/)
Why aren't mountain bikes considered a Off Highway Vehicle? While I don't mind paying to ride, it seems that all users of the trails should pay a share of the maintenance, since all user groups have an impact on the trails. Maybe stay the trail can answer this question?
Federal and state laws differentiate between "mechanized" and "motorized" vehicles and equipment. For example, both types of uses are banned from wilderness areas. The term "Off-Highway Vehicles" (OHVs) is used to describe vehicles propelled by motors as opposed to mechanized equipment, such as bicycles and game retrieval carts, that are propelled by human power with the aid of gears, wheels, pulleys, and such, but not motors. Outdoor recreation enthusiasts may enjoy one or both of these activities. There are both similarities and differences in the experiences and impacts associated with motorized and mechanized recreation. Some of these differences can be significant. One example is the issue of the noise attributed to motorized recreation. As with all forms of recreation on our public lands, there is often tension and even conflict between different user groups.
To say all users of public lands trail systems should pay their fair share for planning, construction, and maintenance of those trails is a reasonable statement. However, getting to a completely fair system continues to be elusive. Even among OHV enthusiasts, there is on-going debate about the fairness of state OHV registration programs that exempt licensed, "street legal" 4x4 vehicles and motorcycles that do not contribute directly to the programs. The land managing agencies are generally directed to utilize the concept of multiple use on public lands not otherwise set aside for specific purposes. They too have a difficult job of accommodating different, sometimes competing, uses. All users of our public lands have a responsibility to keep themselves aware of the ongoing resource management planning and implementation processes and to participate and provide input, either individually or through advocacy groups. This includes how taxes, registration fees, and other user fees are charged and applied.
Stay The Trail's main goal is to provide educational tools and resources for teaching and encouraging responsible use of sustainable trail systems on our public lands, particularly those that accommodate motorized recreation.
I am going to be hunting in Colorado and want to know if the routes I use to access the Game Management Unit are open for my vehicles. Where can I find this information?
Unfortunately, there is no quick, easy, way to get this information. To start, visit the Colorado Division of Wildlife's Game Management Unit Mapping Page at http://wildlife.state.co.us/Hunting/GMUnitMaps.htm
Once you have located your Game Management Unit, you can use the information provided on the Stay The Trail website.

Can I use my OHV to retrieve game during hunting season?
No. There are a few companies that make extended lines for winches or other retrieval methods, but leaving the designated route to retrieve game is not permitted on public lands.
We want to go ride on the Alpine Loop in Southern Colorado, but we've heard some confusing rules... What do we need to know?
Here are the regulations that you will need to be aware of when travelling the Alpine Loop:
1. You MUST have a State of Colorado OHV Permit (or registration) on your ATV to ride on any public lands in Colorado. This applies to OHV's that have a license plate from other states as well.
2. The State of Colorado does not allow ATV's for use on state highways (ie-CO149 through Lake City), regardless of licensing in other states. This has been confirmed this with the Colorado State Patrol.
3. If you ride an unlicensed (by Colorado Law) vehicle on a State Highway, you will get, at minimum, a hefty ticket.
4. Some counties do allow for limited ATV travel on SPECIFIC, DESIGNATED portions of road... check with the local sheriffs. That said, a county cannot overrule State Law on state highways (ie- the highway you'd have to ride to complete the loop)
5. Liability insurance is required
6. On the Alpine Loop, a drivers license is required for the operator (any state, as long as its valid)
7. There is a shuttle service that will pick you and your machine up, run you through Lake City, and drop you off.
8. Black Bear Pass is not advisable on an unlicensed (by Colorado Law) OHV, as it is one-way after the summit and you cannot ride through Telluride to get to Imogene Pass. Imogene Pass is open to unlicensed OHV's from both directions, but again, you cannot ride into the towns of Telluride or Ouray.
I still have other questions, who can I contact?
