On the sidewalks of two streets in Quebec, white triangles have appeared in recent weeks. These are dragon teeth. Far from biting, they rather aim to improve road safety.
It’s a test, it’s the first time.explains Pierre-Luc Lachance, vice-president of the Quebec City executive committee.
It is a mark on the ground that is made to help stop vehicles.he explains.
The new concept is being tested on Notre-Dame avenue, in the airport district, and on Saint-Félix street, in Cap-Rouge.
We really want to try these places. We are going to put speed contrails (…). We’ll have the data, then we can see the effect it has.adds Lachance.
It gives the impression of a narrower track.
Pierre-Luc Lachance explains that the successive triangles painted on each side of the track are intended to give drivers the impression that the track is narrowing and therefore make them slow down.
Similar agreements exist in Ontario and Australia. In Spain, authorities are in the testing phase and dragon teeth could one day spread to other countries in the European Union.
For Michèle St-Jacques, professor of construction engineering at the School of Higher Technology (ÉTS), the concept deserves to be tested here:
It’s original, because it doesn’t cost much to make..
New road markings on two Quebec streets to encourage users to slow down.
Anyone who has studied road markings in more than ten countries believes that
In principle, drivers must understand that they must drive on the black part and not on the marked part..
But will it work? That remains to be seen. she adds.
Radio-Canada noted that, on the ground and on Facebook, many citizens have questioned the white triangles since their appearance.
When Radio-Canada visited the streets in question, many drivers entered the triangles without slowing down.

Michèle St-Jacques hopes that dragon teeth will be effective. However, she believes the real solution lies elsewhere.
We recently carried out a study that shows that 85% of Quebecers are in favor of photoradar and that this percentage is even higher in school zones and near construction sites. explains the teacher.
This is perhaps the simplest way to get people to slow down, because if all these measures that we are trying to get people to slow down, we would have to opt for a more deterrent measure. she adds.
