On 8 January 2023, 40 people were killed and 101 injured in central Senegal when two buses collided in Gniby near the regional capital of Kaffrine on the N1 national road.

Africa Transport Policy Program, which works on developing transportation policies, has referred to an “epidemic of road fatalities and serious injuries.” More than 270,000 people die in vehicle collisions in Africa each year, and the World Health Organization projects that figure will nearly double by 2030, in part due rapid urbanization.

[2][8] President Macky Sall declared three days of national mourning after the accident, to be observed on 9–11 January 2023.
