What are Speed Limits by Zone?
Speed limits vary by road zone and type to protect safety. Highway zones allow 120 km/h, urban city streets 50 km/h, residential areas 30 km/h, and school zones 30–40 km/h depending on time and conditions.
Speed limits are zone-based: highways 120 km/h, urban streets 50 km/h, residential 30 km/h, and school zones 30–40 km/h during school hours or as marked.
Step-by-step worked examples
You are on a highway marked 120 km/h. Traffic is light and road is clear. What is the legal limit?
Highway zone: legal limit is 120 km/h Light traffic does not change the speed limit You must not exceed 120 km/h regardless of conditions
Driving on a city street in an urban zone (no school nearby). Speed limit sign shows 50. You see signs ahead: "School Zone 30 km/h." What speed applies?
Current urban zone: 50 km/h applies now Approaching school zone: limit changes to 30 km/h Reduce speed to 30 km/h as you enter school zone
A residential area at 3 PM. Speed limit sign reads 30 km/h, no special times marked. Is this the limit?
Residential zone with no time restriction: 30 km/h always applies Unless sign specifies different times, limit is constant 30 km/h is the legal limit

Common mistakes
Assuming light traffic allows exceeding the speed limit. — Correct: Speed limits are legal maximums; traffic conditions don't change them.
Not reducing speed when entering a school zone. — Correct: School zones typically have lower limits (30–40 km/h); reduce speed promptly.
Thinking all urban zones have the same speed limit. — Correct: Speed limits vary by zone type (residential 30 km/h, urban 50 km/h).
Ignoring time-restricted school zone signs. — Correct: Some school zones apply only during specific hours; check signs carefully.
