All-terrain vehicles (ATV) are achieving wider response and significance in the present world. With their characteristic abilities of getting through any terrain along with their simple and compact structure, they rule the off-roading world. A new field of engineering research has been developed because of the increasing number of ATV accidents. For determining the reasons to how so many crashes occurs and how they can be prevented, a series of ATV tests were conducted. The tests included simulating an ATV for frontal impact, side impact and rolling over with added weight of a passenger, and due to a thrust effect. Through testing, the amount of weight needed to flip an ATV was determined. This paper highlights the ways to analyse the safety of its chassis in case of impacts or roll overs.
