Off-Highway Trail Rating System
The Arizona State Association of Four Wheel Drive Clubs uses the
following rating system to establish the relative difficulty of
Class 1 Passable by stock and two-wheel-drive vehicles;
improved dirt, gravel, etc.
Class 2 Ground clearance required for stock two-wheel-drive
pickups, vans, etc. Some mudholes or rocks that would stop most
vehicles. Four-wheel-drive makes travel easy where others would have
Class 3 Four-wheel-drive required in places, due to terrain
and loose traction, for safe, easy travel. Low-range gears used
occasionally. Street tires unacceptable.
Class 4 Four-wheel-drive required, usually in low range.
Greatest amount of ground clearance handy due to moderate sized rocks
and obstacles. Jacks and winches advised.
Class 5 Not advisable for novice drivers without experienced
help. Potentially dangerous situations! Maximum ground clearance and
lowest gears required. Jacks or winches indispensable when needed due
to large boulders, steep inclines, etc.
