Reader question: How much do you have to exceed speed limits by to get a fine?

A certain leeway is allowed before you will be fined after being flashed by a camera.

The level fixed for this for a roadside camera is 5kph in areas where the speed limit is up to 100kph, then 5% above this.

In practice, this so-called marge technique (technical margin) is taken off the recorded speed before checking to see if you should be fined.

For example, if you are flashed doing 100kph, then your speed will be taken as 95kph. If you are flashed doing 120kph, your speed will be taken as 114kph.

It means you would have to be flashed at 56kph in a 50kph zone or 137kph in a 130kph zone before you receive a fine.

The same margin applies to stationary cameras, including those used by police or gendarmes from a parked car, or moveable ones placed in a fixed spot.

However, there is a more lenient margin for cameras carried on board cars, whether police cars or unmarked ones operated for the state by private companies.

This is 10kph up to 100kph, and then 10% after that.

Speeding fines show both vitesse enregistrée (speed recorded) and the lower vitesse retenue (speed retained).
