The Federal Road Safety Commission (FRSC) says it recorded 94 deaths in 191 road accidents across the country in the last five days.
A statement issued by Mr Jonas Agwu, the Public Education Officer of the Commission, quoted Mr Osita Chidoka, the Corps Marshal of the FRSC, as giving the figure.
Chidoka gave the statistics after an aerial patrol on Tuesday.
The commission identified over-speeding as one of the major causes of the crashes.
The Chief Executive Officer of the FRSC expressed serious concern over the development.
He said: "It is an attitudinal issue as this year witnessed rehabilitation of major corridors of the highways.
"People tend to disregard traffic laws on speed limits and accelerate beyond recommended speed.
"This has resulted in the figures we have witnessed in the last five days.
"However, we have devised measures to address this unpleasant development."
The statement noted that the Federal Ministry of Works and the Federal Road Maintenance Agency had rehabilitated many roads.
It noted that the rehabilitation was carried out after the report of an audit conducted by the FRSC was submitted.
The aerial patrol took the team, led by Chidoka, to the Abuja-Lokoja, Lokoja-Okene, Asaba-Onitsha highways and the 9th mile corner in Enugu State, among others.
"The purpose of the surveillance is to identify areas of gridlock and resolve them to ease traffic flow," the statement added.
