Here is an updated table with a little bit more of an explanation of the classification system as per 4wd Qld. Please click on the file for a better image.
EXPLANATION OF THE TABLE
The classification will be judged on the most difficult section of the track with a dry weather classification and should be upgraded during planning or decision time if weather conditions deteriorate. EG. A black diamond classified track could contain black diamond, blue square and green circle areas, however it would not contain any double black diamond areas. Each driver should use their judgment to recognize that weather conditions can alter the classification. In saying this, a blue track could clearly become a black, or maybe even a double black diamond track. This is something that each driver should give due consideration.
DRIVER TRAINING:
Because this is a guide only, the suggestion that the driver should have driver training or be experienced, acts as a guide to the potential inexperienced user that it is in their best interest, and that of their vehicle and the track, that some driver training and/or experience is deemed advisable.
OBJECTIVE CLASSIFICATION:
The aim of the classification is to have minimal subjective comments, i.e. there is no mention of steep, boggy or rutted, as these are subjective terms, and different individual interpretations may apply. Ground clearance on the other hand is one area that is fairly universal for 4WD vehicles with low range capabilities, and the driver, with this knowledge can determine whether their journey along a particular track or road would be one of comfort or discomfort.
TYRES:
The classification of tyres is quite simple and implemented to encourage the driver to consider tyre traction and the possible damage to tyres on rough tracks and roads.
HIGH / LOW RANGE:
The notes referring to low and high ratio/range aid the driver in determining how much of the steeper terrain there will be to negotiate along the track. Obviously, if low ratio/range is required, there is going to be at least a small amount of steep terrain.
RECOVERY EQUIPMENT:
The comments about recovery equipment is advisory and in line with Adventure Activity Standards and are also not mandatory; however it is advisable that this equipment be carried in all vehicles for potentially difficult situations.
