Question: In Ontario, what speed rule applies in a freeway when unposted?

Answer options:

• Standard 50 km/h applies ✅ the limit is 80 km/h
• There is no specific rule
• Posted speed always applies

Correct answer: the limit is 80 km/h

Explanation: Under Ontario's Highway Traffic Act, when a freeway or rural highway has no posted speed limit, the statutory default limit is 80 km/h. The 50 km/h limit is incorrect because that standard default applies only within cities, towns, and built-up areas. Believing there is no specific rule or that posted speeds always apply is incorrect, as provincial law provides these automatic defaults to ensure safety when signage is absent. On the G1 exam, memorizing these two unposted statutory speed limits—50 km/h for built-up zones and 80 km/h for elsewhere—is essential for passing the rules of the road section.
