Definition
Minimum speed is the speed below which it is forbidden to drive without a justified cause (slow vehicle by design, obstacle, weather, etc.). On motorways and dual carriageways, the default minimum is half the posted maximum, unless a sign indicates otherwise.
Key facts
- Motorway and dual carriageway: default minimum 60 km/h (half of 120).
- Vertical sign R-411 can set a different minimum.
- Driving abnormally slow without cause is a serious offence.
- Bicycles and special vehicles may go slower if their design speed requires it.
