Dynamic riding on all terrain vehicles
The unique design that makes ATVs so versatile also means that without proper precaution the vehicles may be more likely to roll over.
Four-wheeled all terrain vehicles (ATVs) are versatile and popular workhorses on many farms and properties. They are also the second major cause of fatality in the rural industry – claiming the lives of up to 10 people each year on average, nationally.
The industrial models of ATVs – compared with recreational models – are designed for power, traction and stability. They are used widely for inspection activities on the property as well as for mustering, seeding, fertilising, applying chemicals, slashing grass, moving soil and towing.
The unique design that makes ATVs so versatile also means that without proper precaution the vehicles may be more likely to roll over. A large proportion of ATV injuries and deaths result from the vehicles overturning.
Unlike the lean on two-wheel bikes the design of four-wheel ATVs requires the rider to adopt a "dynamic riding” style. This means that riders must use whole body movement on the seat to effect a turn, or move forward and backward to maintain stability when riding up or down slopes. Riders untrained or inexperienced in the dynamic riding style are more likely to roll an ATV. This also makes ATVs unsuitable to be ridden by children.
Unless specified by the manufacturer, ATVs are not designed to carry a passenger. The additional person’s weight and presence can interfere with the normal dynamics of the vehicle and complicate its handling.
ATV roll over can also be caused by loads that are too heavy, unequally distributed or not secured properly, in particular, spray tanks added to front and rear carry racks. These loads may also interfere with an operator’s ability to effectively control the ATV.
Unlike tractors, there is no Australian Standard applicable to roll over protection for ATVs. Injury risk minimisation from ATV roll over is further complicated by the ability to operate the ATV at much higher speeds thereby potentially exposing the operator to a multiple roll over situation.
Other situations involving ATVs that have resulted in injury include feet and legs being caught in rear tyres, chains or foot rests, and the rider being struck by overhanging branches.
