What does the Concealed Driveway Sign mean?
A concealed driveway is a private entrance to the main road that is not visible until a vehicle on the main road is very close to it. Trees, shrubs, fences, or terrain can block the view of the driveway from the road. The sign warns drivers that a vehicle may suddenly appear from the concealed entrance.
What to do when you see it
Reduce speed and watch for vehicles entering from the concealed driveway. Be prepared to brake suddenly. Avoid overtaking near concealed driveway signs, as a vehicle pulling out at the same time creates a three-vehicle conflict.
Where you'll see it in Ontario
Concealed driveway signs appear on rural roads and suburban arterials where driveways are hidden by hedges, stone walls, hills, or dense landscaping. They are most common on country roads in the GTA belt where agricultural and residential properties have long lanes.
G1 test relevance
This sign appears in G1 warning sign identification sections. Candidates should understand that it represents an increased hazard from unseen vehicles, not just poor road geometry.
Common mistakes drivers make
Speeding past a concealed driveway sign because no vehicle is immediately visible is a common mistake. A vehicle can emerge quickly from a hidden entrance without warning.
