What does the Do Not Pass sign mean in Ontario?
Do not pass other vehicles on this stretch of road
A "Do Not Pass" sign means you may not pass other vehicles on this stretch of road. It is posted where passing would be unsafe, such as near hills or curves where you cannot see far enough ahead.
Why the other answers are wrong
-
Do not enter this road
Do Not Enter is a red sign with a white bar, and it closes the road to you. This white sign is about overtaking, so the road itself is open.
-
Do not stop on this stretch of road
That is the No Stopping sign, posted in pairs to mark an area where you may not stop even for a moment. Passing and stopping are two different rules.
-
Passing lane begins ahead
This is the reverse. A passing or climbing lane gives extra room so faster traffic can get by. This sign removes passing on this stretch, so stay behind the vehicle ahead.
Quick way to remember
Read the words: this regulatory sign is about overtaking.
Based on the official Ontario MTO Driver's Handbook.
