Road Safety by Seasonability in the EU is highlighted at the Traffic Safety Basic Facts 2012 available at the Road Safety Knowledge System of the DACOTA project within the framework of the European Road Safety Observatory of the European Commission. Although the annual number of people who died in road traffic accidents in Europe has fallen over many years, the distribution of the annual number by month has scarcely changed. Motorcycling is the mode of transport with the most seasonal fatality distribution.
