dos d'âne

OBS: À ne pas confondre avec le dos d'âne allongé (speed hump).
OBS: dos d'âne : terme recommandé par le Comité de terminologie et normalisé par le Comité de validation du Lexique de la mobilité durable.

CONT: A speed hump is a raised area of a roadway, which deflects both the wheels and frame of a traversing vehicle. It is longer than the wheelbase of most cars; this feature distinguishes it from a speed bump.
OBS: Many people confuse the term speed hump with speed bump. Vehicles traversing a properly designed speed hump at a reasonable speed, i.e. 30 km/h, can drive with relative ease across the hump. Speed bumps, on the other hand, are sometimes installed on private roadways and in commercial parking lots and can be very abrupt and jarring to motorists.
OBS: speed bump: term recommended by the Terminology Committee and standardized by the Validation Committee of the Sustainable Mobility Glossary.
