Some people suffer from "tunnelphobia". They are afraid of driving in a tunnel. Often they take the longer route to avoid tunnels.

For such people; two Dutch organizations, Rijangstlabel and IPZO have organized a training in the newest tunnel in The Netherlands. The training will take place on June 4, in Corbulo tunnel which has not yet been commissioned. A perfect training place.
