Warning signs
Road narrows both sides
What it means
The road becomes narrower ahead on both sides. Slow down and keep to the centre of your lane.
Yellow diamonds (and five-sided yellow-green school signs) warn of hazards ahead.
Summarised from the Alberta Driver’s Guide. Read the original: Traffic control ↗
How to recognise it
A yellow diamond with two black lines that bend inward toward each other: both edges of the road close in.
Where you will see it
Where the pavement becomes narrower on both sides, such as the approach to a narrow bridge.
What to do when you see it
- 1.Slow down before the narrow section.
- 2.Keep to the centre of your own lane and watch for oncoming vehicles, especially wide ones.
On the knowledge test
The guide groups it with other narrow-roadway signs, such as a lane that narrows or ends and a narrow passage. Read which edge moves: here it is both.
