MTO Traffic Control Devices & Signage 5 — Questions and Answers
Question 1: An 'Added Lane' sign tells drivers that:
- A lane is ending and they must merge
- A new lane is beginning and merging is not required (Correct answer)
- The road widens due to a construction detour
- Vehicles must reduce speed before the intersection
Correct answer: A new lane is beginning and merging is not required
An Added Lane sign means a lane is being added to the roadway, so drivers entering from the side road do not need to merge immediately.
Question 2: What does a brown highway sign typically indicate?
- Hazardous road condition
- Nearby hospital services
- Recreational area or cultural interest (Correct answer)
- Temporary traffic control
Correct answer: Recreational area or cultural interest
Brown signs with white lettering direct drivers to parks, historical sites, recreational areas, and cultural attractions.
Question 3: A 'Wrong Way' sign differs from a 'Do Not Enter' sign in that:
- Wrong Way signs are placed mid-road to warn drivers already going in the wrong direction (Correct answer)
- Wrong Way signs permit a U-turn; Do Not Enter signs prohibit it
- Wrong Way signs appear only on highways, not city streets
- Wrong Way signs are advisory; Do Not Enter signs are regulatory
Correct answer: Wrong Way signs are placed mid-road to warn drivers already going in the wrong direction
Wrong Way signs are placed further down the road to catch drivers who have already entered a one-way road incorrectly, while Do Not Enter signs are at the entry point.
Question 4: A traffic control device placed in a work zone to redirect vehicles around a hazard is called a:
- Delineator post (Correct answer)

Correct answer: Delineator post
Delineator posts (channelizing devices) are flexible posts placed to guide traffic around hazards or through work zones.

- You must stop completely before entering
- You must yield to vehicles already in the roundabout (Correct answer)
- You have priority once your turn signal is on
- You yield only to pedestrians, not vehicles
Correct answer: You must yield to vehicles already in the roundabout
At a roundabout, you must yield to vehicles already circulating inside before you enter.
Question 6: What does a 'No U-Turn' sign look like?
- A white rectangular sign with a red circle and slash over a U-shaped arrow (Correct answer)
- An orange diamond with a curved arrow and X
- A yellow circle with the letter U inside
- A black octagon with white lettering
Correct answer: A white rectangular sign with a red circle and slash over a U-shaped arrow
No U-Turn signs are white regulatory signs featuring a U-shaped arrow with a red prohibition circle and diagonal slash over it.
Question 7: Edge line pavement markings on a road serve what purpose?
- Indicate where the center of the road is
- Define the outer boundary of the travel lane (Correct answer)
- Warn of an approaching intersection
- Mark bicycle lanes
Correct answer: Define the outer boundary of the travel lane
Edge lines (white on the right, yellow on the left of divided roads) define the outer edge of the travel lane and help drivers especially in low visibility.
