At least 32 people have died and several others injured in multiple road crashes in Kwara, Kogi and Ogun states.
The Federal Road Safety Corps (FRSC) confirmed the accidents, which occurred between Sunday and Monday.
The Corps blamed the crashes on traffic violations, including speeding, dangerous driving, driver fatigue, poor tyre maintenance and the illegal practice of conveying passengers alongside goods.
The latest incidents add to growing concerns over recurring fatal crashes on Nigerian roads.
FRSC Corps Marshal, Shehu Mohammed, in a statement on Monday, described the crashes as “heartbreaking and entirely preventable”, saying the recurring violations of established traffic regulations continue to undermine national efforts to improve road safety.
Mohammed urged motorists, transport companies and commercial vehicle operators to prioritise safety by ensuring only roadworthy vehicles ply the highways.
The Corps Marshal also warned that the FRSC would sustain aggressive enforcement against all traffic violations that endanger lives.
