The electric wagons known as Stints, used by hundreds of daycare centres to ferry children around until last year’s fatal crash, need to be fitted with extra brakes, infrastructure minister Cora van Nieuwenhuizen has told MPs.

The measure is contained in temporary rules to cover ‘special scooters’ – a new category of road transport introduced in 2011 to cover Segways and which also includes the electric wagons.

In addition, all ‘special scooters’ which transport people must be fitted with seat belts, and can carry no more than eight children at a time, the minister said. The vehicles will also have to undergo a yearly service.

Definitive rules will be drawn up at the end of the year, once the Dutch safety board concludes its research into last year’s crash.

Last September a wagon ploughed into a train at a level crossing after the brake apparently failed, killing four children. Van Nieuwenhuizen immediately banned the wagons from the roads.

That ban is still in force and not affected by the rules published by the minister, which only apply to new forms of transport.
