A survey conducted by World Health Organization (WHO) indicates that Nigeria has one of the worst road death records in the world and this is no thanks to the poor state of our roads and our reactions to Emergencies.

The study measured deaths per 100,000 and Nigeria’s death rate per 100,000 was 33.7 with a slow response to emergencies also, but these figures can’t only be associated with our bad roads alone, the state of the vehicles that ply the roads can’t be ignored because most of them are either not roadworthy or in poor conditions.
