Overview of the Law
Under sections 328–329 of Quebec’s Highway Safety Code, every driver must comply with the posted speed limits. The law sets out general limits such as:
- 100 km/h on autoroutes
- 90 km/h on concrete or asphalt highways
- 70 km/h on gravel roads
- 50 km/h in built-up areas
The Minister of Transport may also adjust these limits based on traffic, weather, or safety conditions. In all cases, exceeding the posted limit constitutes a speeding offence, regardless of the driver’s experience or familiarity with the road.
