According to the African Exponent Kenya, Chad records the lowest road‑quality score in Africa and globally, scoring 1.9 out of 7 and ranking 141st of 141 economies.

Mauritania and Madagascar each receive a score of 2.0, placing them second and third on the continent’s worst‑road list and just ahead of Haiti and Yemen worldwide.

The bottom‑ten list also includes the Democratic Republic of the Congo (2.1), Angola (2.2), Mozambique and Cameroon (both 2.4), Nigeria and Gabon (both 2.5), and Lesotho (2.7).

The scores derive from the World Economic Forum’s Executive Opinion Survey, where business executives rate national road systems on a 1‑to‑7 scale that blends condition and extensiveness.

The latest complete cross‑country vintage of the survey is from 2019; the 2025‑26 VizAtlas edition republishes those figures, noting that the ranking year reflects the edition, not a new field survey.

The African Exponent notes that the poor rankings are driven by limited fiscal capacity for maintenance, harsh terrain, and, in some cases, conflict or extreme weather, rather than a country’s overall wealth.

Nigeria’s position at eighth worst (score 2.5) illustrates that a large economy does not guarantee road quality; chronic underfunding and fragmented responsibility between federal and state authorities impede upkeep.

The ranking highlights that three of the five worst road networks worldwide are African, with Chad, Mauritania and Madagascar occupying the global bottom three.
