This comes hours after the Punch newspaper reported that 14 people died in the southwestern state of Osun on Saturday night in a crash involving a truck and a minivan. Four others were injured.
Federal Road Safety Corps (FRSC) chief Boboye Oyeyemi said in a statement that he was concerned by a rise in the number of fatal crashes and drivers working without valid licenses.
Road police have been told to check commercial and articulated vehicles for the mandatory speed-limiting devices. The rules are aimed at "restoring sanity to the nation's highways," FRSC said.
