Motorcycle Passenger Helmet Use in Cambodia – A turning Point?

EXTENDED ABSTRACT: This abstract examines January 2016 start of enforcement of Cambodia’s road traffic law as a potential turning point for passenger helmet use (PHU) among motorcyclists. Focus is on Kandal, Kampong Speu, and Phnom Penh provinces, where concerted efforts toward increased PHU have been underway since 2010, first with the Cambodia Helmet Vaccine Initiative (CHVI); and its scale up under the 2014-2016 USAID-DIV funded “Head Safe. Helmet On.” (HSHO); implemented by AIP Foundation. School-based education, helmet/voucher distribution, public awareness campaigns, and advocacy and capacity building are combined to steadily increase PHU rates, which jumped subsequent to enforcement start.
