BACKGROUND: Motorized 2-3-wheelers-related death is high due to the exposed body of the driver/passenger and the high speed. The United Nation (UN) Decade of Action for road safety aimed to reduce road traffic deaths by 50% by the year 2020.

We aimed to study the factors affecting the death rates of motorized 2-3 wheelers injured victims and whether the reduction in the death rates has met the UN target. METHODS: Data were retrieved from the WHO Global Status Reports on Road Safety published over 2009 to 2018 which covered the years of 2007 to 2016.

Studied variables included motorized 2-3 wheelers death rates, percentage of helmet-wearing rate, helmet law enforcement, speed law enforcement, gross national income per capita, vehicles/person ratio, and motorized 2-3 wheelers/person ratio. A mixed linear model was used to define factors affecting the change of motorized 2-3 wheelers death rates over time.

RESULTS: The global mean motorized 2-3 wheelers death rates increased from 2.37/100,000 population to 3.23/100,000 population over the studied decade (a relative ratio of 1.36) which was not statistically significant. Factors that affected mortality included GNI (p = 0.025), motorized 2-3 wheelers per person ratio (p < 0.0001), percentage of helmet wearing rate (p = 0.046), and the interaction between vehicle/person ratio and motorized 2-3 wheelers/person ratio (p = 0.016).

There was a significant increase in the death rates over time in the low-income countries (a relative ratio of 2.52, p = 0.019, Friedman test), and middle-income countries (a relative ratio of 1.46, p < 0.0001, Friedman test), compared with a significant decrease in the high-income countries (a relative ratio of 0.72, p < 0.0001, Friedman test). CONCLUSIONS: Global mortality of motorized 2-3 wheelers has increased by a relative ratio of 1.36 over a recent decade.

The UN target of reducing death was not met. The increase was related to the increase in motorized 2-3 wheelers per person ratio and economic inequity which has to be addressed globally.

The economic global gap significantly impacts the mortality rates of motorized 2-3 wheelers.
