I would want to suggest that the country adopt two different colours for the ambulance service in the country. One colour for a medic (National ambulance) and one different one for the Hearse(Dead body vehicle) like the taxis are made to.
They keep confusing people when driving especially at the weekends. And like we will all agree there is no urgency in transporting a dead body not to talk of the sirens.
After implementation, MTTU and DVLA to monitor for adherence to ensure such cars are sprayed in the designated colours. My humble contribution to nation-building.
