Off-road vehicle safety depends on more than whether the vehicle can keep moving. Uneven ground, limited visibility, changing traction, and distance from help can turn a manageable mechanical problem into a serious situation. Clearance and traction aids address particular demands; they do not establish a safe route, protect an unrestrained occupant, or make floodwater passable.
A useful safety assessment considers the vehicle, its occupants and load, the route, and the driver's ability to recognize a reason to stop. This applies to terrain-capable passenger vehicles; ATVs and other recreational machines have different requirements. For any passenger vehicle, the exact manufacturer instructions and current local conditions remain essential.
