Bern, Switzerland (GenevaLunch) – Speeders beware: France and Switzerland have just swapped data on 30,000 drivers who’ve been caught going over the limit, in order to send them speeding tickets.

The two countries began exchanging data in January, with Switzerland receiving data on more than 20,000 drivers since 5 January, while France has received 10,000 since 19 January. Geneva and Basel area drivers are most affected, but the Swiss federal highway department notes that there’s a sharp increase in many areas during vacation travel periods.

The new exchanges are similar to a system Switzerland and Germany have had in place since 2006. The data swap must go through the federal highway department, which transmits data via Eucaris, a European-wide system that is being developed to exchange car and drivers’ license registration information. Italy and Austria are not yet fully integrated, so Switzerland does not yet have speeding data swaps with these countries.
