This sign means?
- Indicates a lower speed limit ahead ✓
- Maximum speed of 50 km/hour from this sign to next sign
- Speed limit for rural school zones
- End of 50 km per hour zone
Answer: A. Indicates a lower speed limit ahead
This sign indicates that a lower speed limit is coming up ahead.
Why this is the answer
The handbook's list of signs in the signs, signals and road markings chapter includes one that tells drivers a lower speed limit is ahead. So the sign is a warning about a change coming, not a statement of a specific number you must obey from that point on. It tells you to expect a slower posted limit further along the road and to be ready to adjust your speed when you reach it.
Why the other answers are wrong
- B. Maximum speed of 50 km/hour from this sign to next sign — A sign giving a top speed of 50 km/h from that point to the next sign would set the limit right there, while this sign only warns that a lower limit is coming.
- C. Speed limit for rural school zones — The handbook describes school zones with their own speed tabs and the hours they apply, which is a different sign from one warning of a lower limit ahead.
- D. End of 50 km per hour zone — The handbook says you know you have reached the end of a 30 km/h school zone when you pass the back of the school zone sign, so ending a zone is handled by that sign, not by this warning.
Remember it
Treat it as a heads-up, not a number: slow down and watch for the new posted limit ahead.
