46. Traffic mirror

A traffic mirror is a convex mirror installed near an intersection, driveway, bend or other location with restricted visibility. Its curved surface provides a wider view of approaching road users than an ordinary flat mirror.

A traffic mirror is only a visibility aid. It may distort distance, speed and direction and may be affected by darkness, weather, dirt or damage. Drivers must continue to observe the road directly, obey all priority rules and proceed only when it is safe.

What is a traffic mirror?

A traffic mirror is a roadside visibility aid that can help users see around a blind corner or obstruction. It gives an indirect view, which may be restricted or distorted; it does not replace checking whether it is safe to proceed.

Does a traffic mirror show an exact image?

No. The reflected image can be distorted, and glare, bad weather or dirt can restrict the view. Judging an approaching vehicle’s speed from a mirror can be difficult. Do not rely on the mirror alone.

Does seeing an empty mirror mean the road is clear?

No. Another road user may be outside the reflected area, hidden by glare or too small to notice. Always check the road directly before proceeding.
