This study explores factors that lead towards aggressive driving behaviour among Malaysian drivers and to determine the highest factor that contributes to these aggressive driving styles in Malaysia. Driving aggressively increases the chances of drivers becoming involved in a motor vehicle crash, and aggressive driving behavior occurs happens due to multiple factors. The Driving Anger Expression Inventory (DAX) is used to calculate the factors corresponding to their anger while driving. There are four factors that has been identified to define how people expressed their anger while driving by using DAX, they are Verbally Aggressive Expression (α=0.7332), Physically Aggressive Expression (α=0.8548), Using the Vehicle for Aggressive Expression (α=0.7267) and Adaptive/Constructive Expression (α=0.8711). At the end of this research, we found out that the Adaptive/Constructive Expression is the highest factor and most commonly used amongst drivers to adapt to these aggressive situations on the road. Followed by the factor Verbally Aggressive Expression and Using the Vehicle for Aggressive Expression. Then, the least often used factor in Malaysia is Physically Aggressive Expression. Therefore, some mitigation plans should be considered towards reducing accidents in Malaysia which is on a yearly rising trend.
