• Benin orders crackdown on overloaded, oversized trucks

• UEMOA rules cap weight at 51 tonnes

• ECOWAS road maintenance gap estimated at $9.5 billion

Benin has launched a crackdown on road traffic violations linked to overloaded and oversized trucks, following several months of awareness campaigns for transport operators conducted between June and October 2025.

In a statement, the Ministry of Living Environment and Transport said it had instructed the Republican Police to carry out systematic enforcement actions against offenders.

The move forms part of a broader national strategy to protect road users and preserve infrastructure. It also underscores a recurring regional challenge: the consistent enforcement of load-control standards within the West African Economic and Monetary Union (UEMOA).

Uneven enforcement of regional standards

The fight against overloading is governed by UEMOA Regulation No. 14/2005/CM, which harmonizes rules on vehicle dimensions, weight and axle loads across member states. The regulation sets the maximum vehicle length at 22 meters and the maximum gross vehicle weight at 51 tonnes.

In practice, enforcement remains inconsistent. According to experts from the regional bloc, member states tend to alternate between periods of strict enforcement and phases of weaker oversight. When inspections ease, violations often rebound.

Benin’s case is not unique. Burkina Faso and Mali launched similar enforcement campaigns in June and April 2025, respectively. While these initiatives reflect a broader push to strengthen compliance with regional rules, they also highlight the difficulty of ensuring uniform enforcement along interconnected transport corridors.

Infrastructure under fiscal strain

Beyond road safety concerns, overloading carries significant economic costs. Marion Vern Vinagbon Ayinon, a UEMOA expert interviewed by Agence Ecofin, said the main consequence of non-compliance with harmonized standards is the premature deterioration of road infrastructure. Excess weight accelerates pavement wear, shortens the design lifespan of roads and forces governments to carry out costly repairs more frequently, at a time when budgets are already constrained.

A May 2024 report by the African Road Maintenance Funds Association (AFERA) estimates that ECOWAS countries require $10.4 billion annually to finance road maintenance. However, only about $1 billion is mobilized each year, leaving a financing gap of roughly $9.5 billion. Against this backdrop, overloading further increases fiscal pressure by widening the gap between maintenance needs and available funding.

Toward a shift in transport patterns?

Stronger enforcement alone may not be sufficient. West African economies rely heavily on road transport, including for long-distance and heavy freight flows. According to Ayinon, a shift toward greater use of rail could help reduce pressure on road networks. Expanding modern railway infrastructure would allow rail to carry a larger share of heavy cargo, limiting premature road degradation.

Such a transition would require substantial investment and closer regional coordination. In the meantime, the effectiveness of national anti-overloading campaigns, including Benin’s latest initiative, will depend on sustained enforcement and genuine alignment of control practices across member states.
