This is the system used by Bad Ass 4x4s.
|1||1-2||A trail rating of one indicates a beginners trail. Little to no threat of vehicle damage. Stock vehicles will make the trail with ease. Family friendly trail, all obstacles are avoidable.|
|2||3-4||A trail rating of two indicates a low amount of difficulty. It is recommended that beginners and people with stock rigs should go out with a more experienced person. Most trail obstacles are avoidable, but not all of them. It is recommended to at least have one or the other; mud tires or a lift.|
|3||5-6||A trail rating of three indicates a more advanced trail. These trails are moderately difficult. Body damage and or personal injury are possible. Beginners are strongly recommended to ride these trails with more experienced people. A lift and mud tires are recommended. Many obstacles on these trails are unavoidable.|
|4||7-8||A trail rating of four indicates danger. Beginners should never try these trails alone. A lift and mud tires are strongly recommended. No stock vehicles should attempt these trails. Body damage and or personal injury are possible.|
|5||9-10||A trail rating of five indicate an extreme trail! Never to be attempted by beginners or stock vehicles. A fully trail capable vehicle is not only strongly recommended but needed. Heavy-duty recovery equipment strongly recommended (winch, tow straps, etc.) Body damage and or personal injury are likely! Ride these trails at your own risk!|
Note: Trail ratings are highly subjective. A trail that is easy for an experienced driver with a highly modified vehicle may be impassable for a novice driver in a stock vehicle. Weather conditions may also significantly affect the difficulty of a trail. Also, the difficulty of a trail may change over time, as trail use, weather, and maintenance modify the trail. Always check with the managing organization and/or recent users before planning a trip on a trail and scout ahead on foot if you are not sure of current conditions.
