The table details the number of five vehicles in Australia across three years:2010, 2012, and 2014. Overall, it is evident that all categories followed a similar upward trend albeit to varying degrees, with passenger vehicles registering the highest figures throughout the period. On the other hand, light trucks were the least preferred mode of transportation.
Focusing on the categories with the highest figures, passenger vehicles ranked first with an initial figure of 11,000,000 vehicles in 2010 increasing gradually to 13,000,000 vehicles in the final year, marking an 18.2 % change. Commercial vehicles were the second most popular group. Having increased from 2,300,000 cars to 2,600,000 by 2012, the number of cars continued to rise and constituted 2,700,000 in 2014, demonstrating a 17.4% increase over the years.
Motorcycles and light trucks were less popular; however, they demonstrated a more dramatic percentage increase over four years. Starting with 570,000 in 2010, the number of registered motorcycles surged to 725,000 by 2012 and then increased further to 745,000 in 2014, which indicated a 30.7% growth in total. Similarly, there was a 23.5 % increase in the number of light trucks; the quantity of those increased steadily from 106,000 cars in 2010 to 131,000 vehicles in 2014.
Finally, heavy trucks detailed the smallest percentage change over the years. While the number of heavy trucks grew negligibly from 384.00 to 386,000 in the first two years, it reached only 423,000 in the last year, marking a 10.2 % change.
