About Amend

Our vision is a future in which vulnerable road users in sub-Saharan Africa are as safe as road users anywhere in the world.

Our mission is to develop, implement, and evaluate evidence-based interventions to reduce the incidence of road traffic injury among the most vulnerable road users in Africa today while working to help create an environment for long-term, sustainable injury reduction.

We run our own programs and partner with governments, companies, development agencies, and others on projects that target specific aspects of road traffic injury. Visit the Our Work section for more information on our activities.

The World Health Organization (WHO) has said that “the interventions promoted by Amend are perfectly in line” with those being promoted by the WHO and Amend is a member of the United Nations Road Safety Collaboration, the coordinating body for road safety issues across the United Nations system.

Amend’s work has been featured on the BBC, and PRI’s “The World,” as well as in the CS Monitor, Newsweek, and other international and local media outlets.
