Over the last 15 years, CIECA has managed or participated in a number of different international studies relating to driving licensing, driver training and driver testing. Many of these studies and projects were commissioned and subsidised by DG TREN of the European Commission (Transport and Energy Directorate of the European Commission). 

The majority of the studies look into the driving test for the various vehicle categories and the requirements listed in the European Directives 91/439/EEC and more recently Directive 2000/56/EC on driving licences. The studies consider questions like: how have the obligations laid down in the Directive been implemented in each EU Member State? Are these obligations justified and proportional? Has the Directive aided mutual recognition of driving licences across the EU and has road safety been enhanced as a result? 

More recently, CIECA has also been involved in projects looking into driver training; in particular, into advanced or second phase driver training and the integration of multimedia tools and simulators into driver training.
