National Speed Limit Sign
This sign restores the general speed limit after a lower posted limit ends. The applicable number depends on the road type, per Speed Limits.
Meaning
Sign indicating the general (default) open-road limit applies.
Required driver response
Apply the default general limit for that road type — 120 km/h on a freeway, 100 km/h on a rural public road — unless a posted sign shows otherwise.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see this sign?” — required response.
- Distractor trap: thinking it sets a specific new number rather than restoring the default limit.
