Hello,
Waze routing for finding alternatives in the event of a slowdown, closed road, or accident does not depend on the Editors but on the algorithm.
The algorithm will always seek to guide you along the fastest path while taking legislation into account: Waze is in no way responsible for speeding or other violations of the Highway Code.
Editors do not have the ability to direct traffic to a specific place (such as onto the N40 as suggested).
Just as Waze is not responsible for violations of the Highway Code, Waze is not responsible (and can do nothing) when users employ Waze even though it is not intended for them: Waze is intended for cars and motorcycles, and in no way for other vehicles.
At the intersection between rue des Vieux Prés in Léglise and the N40, the vehicles for which Waze is designed have no problem turning (otherwise, a driving school refresher course would be necessary).
Passing through Thibessart is logical, and faster, to get back onto the E411 at exit/entrance 28a (Rulles).
Safe travels with Waze!
