What is PTI

The PTI - a success story

The periodical inspection of vehicles in traffic (Periodical Technical Inspection - PTI) has been recognized worldwide for decades as an important and integral part of environmental compatibility and road safety. In 1977, the guidelines for the approximation of the legal provisions of the member states on technical surveillance were developed from the standards that had already been tried and tested in the individual EU member states, which specifies (minimum) standards for the PTI. In 1997 the UNECE agreement on uniform conditions for periodic technical inspections and the mutual recognition of the test results followed - against the background of the successful application of the repeatedly updated EU PTI Directive (currently: 2014/45 / EU). This laid the foundation for further developing the PTI on a harmonized basis beyond the EU framework.

Just as the leading role of the UNECE (agreement of 1958) is undisputed with homologation regulations for vehicles and vehicle parts, the EU will be a pioneer in the further development of the PTI for the foreseeable future. The international PTI committee CITA has an important function in the process of further developing the content of the regulations.

The adaptation of the PTI regulations, as they are anchored in the EU directive currently to be implemented, mainly includes innovations in quality management. For example, a central supervisory body for quality in vehicle monitoring must be set up in every EU country, following the example of Germany. The use of intelligent driver assistance systems, the increase in electronic components and the connection of vehicles to the Internet with ever increasing environmental regulations will also have an impact on the future content of the PTI. For example, the use of the electronic vehicle interface is explicitly listed - in Germany this has been standard in the main inspection since 2015 in the form of the HU adapter.

The primary goal should now be to align the currently still divergent approaches of the EU and UNECE as quickly as possible, taking into account the general progress in vehicle and testing technology. The global concern for even more road safety can best be met through a further update of the UNECE agreement of 1997.
