A permanent speed trap has been introduced for drivers heading to Amsterdam on the A2 motorway to make sure they don’t break the 100 kph limit, the NRC reports on Monday.

The speed trap consists of banks of cameras between the Maarssen and Holendrecht exits which are used to calculate the average speed of motorists over the 17 kilometre stretch of road. Those whose speed is over 100 kph can expect a fine.

A similar speed trap has been operating on the five-lane highway heading towards Utrecht since July last year. Between July and September, 190,000 motorists were fined, raising €13.5m for the treasury.

Limits

The speed limit on that road has since been increased to 130 kph between 19.00 hours and 06.00 hours.

The aim of the constant speed check is to reduce noise and pollution in population centres close to the motorway and improve road safety, the NRC said.

The justice ministry said in May that traffic police handed out 3,750,000 fines in the first four months of this year. The 30% increase on 2012 is largely due to speeding tickets generated by speed traps.

Speed traps on the A4 motorway accounted for almost one third of these. Speed limits on Dutch roads can range from 130 kph to 30 kph.
