The Dominican Republic has the highest rate of accidents involving motorcyclists. A Report on Safety of Motorcyclists in Latin America: Trends and Opportunities for Action by the Mapfre Insurance company says that 1,258 deaths and 4,010 injuries were caused by motorcyclists in 2013. As reported in Diario Libre, this is the highest ratio of deaths to inhabitants in the region.
The report presented by the Metropolitan Transport Authority (AMET) says that motorcyclists were involved in 3,819 of the 6,637 traffic accidents in 2013. Juan Gondres, in charge of regulation at AMET, said that in these cases the rider may not have been wearing a helmet, or had crossed a red light, was driving in the wrong direction, was zigzagging among vehicles, was driving at excessive speed, was driving under the influence of alcohol or drugs, or was carrying more than one passenger.
Gondres said that the report assessed the situation in 12 countries in Latin America and found that the Dominican Republic has the highest ratio of deaths per capita: 149 deaths for every one million inhabitants. He said the ratio is four times that of Brazil and Colombia.
As reported, there are 1,678,979 motorcycles in circulation in the Dominican Republic in addition to 1,536,794 four-wheeled vehicles.
