South Dakota Rules for Riding Off a Route
South Dakota’s riding rules can feel confusing when a map shows roads and trails close together, or when a route is blocked and a tempting detour appears. The safest rule is simple: ride only where your machine is specifically allowed, and don’t assume a nearby track is an approved route. Here’s how to read that rule across public and private land.
What riding off a route means
“Off route” generally means operating a motorized vehicle away from a road, trail, or area where that vehicle is authorized to travel. It can include cutting across vegetation to bypass a muddy section, making a new track around a gate, or following tire marks that do not appear on an official map. A route can look well used and still be closed or unauthorized.
The route rule is about more than whether a path is visible. A route’s legal status depends on the land manager’s designations, signs, closures, and limits for vehicle types. A narrow trail may be open to motorcycles but not a wide UTV. A road may be open to some motorized traffic while a nearby trail is closed. Permission to ride in the general area does not automatically authorize riding everywhere within it.
This distinction matters especially in the Black Hills, where roads, motorized trails, nonmotorized trails, private parcels, and restricted areas can sit close together. A route shown on an old map, marked by tracks in the dirt, or recommended by another rider may not be open today. Check the current map and any closure notices before you leave.
A few common examples help:
- Following a designated road or trail: Usually the right approach when the route is open to your machine and the relevant rules are met.
- Leaving the route to go around an obstacle: Not automatically allowed. If the route is blocked, use an authorized alternative or turn back rather than creating a bypass.
- Riding across open ground: Allowed only where the land manager specifically permits that kind of travel. Do not treat an unmarked patch of land as open by default.
- Following tracks that are not on the map: Tracks show where someone rode, not whether they had permission.
- Using a route with a vehicle that exceeds its limits: A route can be open to motorized travel but still unsuitable or unauthorized for a machine that is too wide or otherwise restricted.
Maps and signs are useful, but they answer different questions. A map helps show where routes are designated; a sign may communicate a closure, restriction, or local condition. If the two seem to conflict, stop and confirm the current rule with the land manager instead of guessing.

Where route restrictions apply
National Forest land
On National Forest land, motorized travel is generally limited to routes designated for that use, unless a specific area has been opened to cross-country travel. The relevant motor vehicle use map, often called an MVUM, is a key tool for identifying designated routes and vehicle restrictions. A general recreation map may show roads or trails without answering whether they are open to your machine.
Follow the route shown as open, stay within its travel way, and obey signs at entrances and along the route. A route may be closed seasonally, temporarily, or to particular vehicles. A gate, barricade, or closure notice is not an invitation to take a side track. If you need help understanding the broader rules, see South Dakota Rules for Riding Federal Land.
Do not assume that a road or trail remains open just because it appeared open on a map you saved earlier. Conditions and closures can change, and a map may not reflect a recent restriction. Check the latest information before setting out, particularly after storms, during periods of fire danger, or when a route has been affected by maintenance. If you reach a closure sign, follow it; Riding Past a Forest Closure Sign covers why a marked closure should not be treated as optional.
State and other public land
Different public-land managers can have different rules. South Dakota’s general riding rules do not give riders permission to leave a route on every public property. A state recreation area, wildlife area, federal property, or locally managed site may each have its own designated routes, vehicle limits, and closures.
Some managed riding areas are specifically set aside for motorized use. In an area open to riding, stay within its boundaries and follow posted instructions; the fact that cross-country riding is allowed in one location does not make it permissible on a nearby trail or property. Check the land manager’s information for the exact site, rather than relying on a rule from another riding area.
Road travel and off-road travel are also separate questions. A machine may be allowed on a particular road only if it meets applicable requirements, while a trail may have its own permit or vehicle restrictions. A plate or registration does not grant access to a closed route, and a trail permit does not authorize travel outside the designated area. For the distinction between routes and permits, see Why a Trail Always Needs the Permit and Why a Road Needs a Plate or a Permit.
Private land and public rights-of-way
Private property requires the landowner’s permission. A visible two-track, an open gate, or a route that appears on a recreational map is not proof that the public may ride there. Boundaries can be difficult to see on the ground, especially where public and private parcels meet. When you are unsure, stop before crossing and confirm that you have permission. South Dakota Rules for Riding Private Property explains the importance of landowner access.
A public road or right-of-way is not the same as a general license to ride across nearby land. Stay within the authorized roadway or route and follow any restrictions that apply there. Don’t cut across a field, bypass a locked gate, or use a private ranch road as a shortcut without permission.
| Situation | Safer approach |
|---|---|
| A designated route is shown as open to your vehicle | Stay on that route and follow signs and restrictions |
| A map is unclear or seems outdated | Check current information with the land manager before riding |
| A gate or closure blocks the route | Do not bypass it; find an authorized alternative or turn back |
| A track is visible but not designated | Do not assume it is open |
| The route crosses private property | Get the landowner’s permission before entering |
| A riding area allows travel within its boundary | Stay inside the boundary and follow its posted rules |
What to do when a route is blocked or unclear
A route can become impassable because of weather, debris, construction, a vehicle breakdown, or a closure. The natural instinct may be to ride around the problem, but that can turn a legal trip into unauthorized travel. A detour is not automatically lawful because it seems short or causes little visible damage.
Use this process when you reach an obstruction or uncertainty:
- Stop before leaving the route. Don’t ride into vegetation or onto an unmarked track while deciding what to do.
- Check for signs and map information. A closure sign or boundary marker may explain what is allowed. Review the current route map if you have coverage or a downloaded copy.
- Look for an authorized alternative. Use only a route confirmed as open to your machine. A nearby line on a map may be a nonmotorized trail, a private road, or a route with different vehicle limits.
- Ask the land manager if the status is uncertain. If you cannot confirm that a detour is open, don’t take it.
- Turn back when necessary. Returning the way you came is safer than making a new route or crossing land without permission.
If the route is blocked by a fallen tree or another obstacle, avoid widening the trail by steering around it. If it is safe to do so, report the obstruction to the land manager. Riders should not move barriers or signs, even if the route appears usable beyond them. A closure may exist for a reason that is not obvious at the trail entrance.
A mechanical problem does not create a general right to leave the route, either. If a machine cannot continue, keep it in a safe location and seek assistance through an authorized route. If a recovery vehicle is needed, confirm that its access is permitted. A shortcut across a closed trail or private land can create a second problem while you are trying to solve the first.
Route restrictions protect more than the route itself. Riding around an obstacle can damage plants and soil, widen a trail, disturb wildlife, or create tracks that other riders may mistake for approved routes. Repeated detours can turn a small patch of disturbance into a much larger one. Staying on the established route helps keep riding areas available and reduces conflict with landowners and other users.
How to plan a route without going off it
A little preparation makes it easier to stay legal when maps, signs, and terrain do not match your expectations. Before loading the machine, identify the riding area, check the current route information, and confirm that each planned segment is open to the machine you intend to use.
Pay attention to vehicle width and route designation. A UTV that is wider than an allowed trail limit cannot use that route just because an ATV can. A route may also be limited by season or closed temporarily. If your machine is close to a stated width limit, measure it as the rules require rather than relying on the manufacturer’s advertised figure. [South Dakota Rules for a Machine Over 62 Inches] is relevant when width restrictions may affect your plans.
Plan a return option as well as an outbound route. If a trail is closed or conditions worsen, you should know which open route leads back. Download or carry the current map where practical; cell coverage may not be available throughout a ride. A screenshot or an old printed map can be helpful for orientation but should not replace checking current closures.
Before riding, confirm:
- The land manager and boundaries for the area you plan to visit.
- Which routes are open to motorized use and to your specific vehicle type.
- Any width, seasonal, or temporary restrictions.
- Whether a permit, plate, or other requirement applies to the route or area.
- Whether private property lies along the route and whether permission is needed.
- Where you can turn around if a route is blocked.
Permits and route access are separate. A permit may be required for riding in a particular area, but buying one does not open closed routes or allow cross-country travel. Likewise, a machine’s registration or plate does not override a route closure. Confirm both the access rule and the permit rule before setting out. South Dakota Trail Permits Explained provides more context on how permits fit into a ride.
If you are riding with a group, make sure everyone understands the planned route and agrees not to create detours. The rider in front may see the sign first, but each rider is responsible for following it. Agree in advance that the group will stop and regroup at closures or uncertain junctions rather than splitting onto unverified tracks.
When the route status remains unclear, choose the conservative option: stay put, turn back, or contact the land manager. A visible track, a verbal tip, or a navigation app’s suggested shortcut is not a substitute for permission. Staying on an authorized route is the simplest way to protect your ride, the land, and future access for other riders.
