Yes, the Oregon Class II trails are rated both by color and by the line symbol's curvature or sharpness. A "green" trail is suitable for novice drivers and stock 4wd vehicles. A "blue" trail is more challenging and is suitable for drivers with some degree of 4wd experience. In my experience, stock wranglers are able to transverse most, if not all of the "blue" trails in TSF. Black trails are generally for vehicles with a limited degree of modification, either to suspension, tire diameter, or drivetrain/axle. Experience, whether it be the driver or spotter, is preferred for black trails. I've seen stock wranglers go through black trails such as firebreak 5, due to driver skill (or unfortunately - skinny pedal).
The next degrees of difficulty are the double and triple black trails. These trails are usually ran by trailered rigs. Locked differentials and winches are the norm for these type of trails.
