When Yield Signs are used at right turn camps, particularly where the radius of
curvature is less than 60 m, the visibility of u Yield Sign installed on the right side may
be inadequate, In these situations consideration should be given to installing an
additional sign on the left side.

A Yield Sign may be supplemented by Yield Ahead Sign (WB-2) (Sec. 43.51).

Usage Guidelines
Yield Sign control should be considered when the basic right-of-way rule does not
provide for safe and efficient traffic movements, and a Stop Sign is considered to be too
restrictive, ;

Yield Signs should not normally be used at any intersection where Stop Signs exist.

As a general rule Yield Signs should only be used where traffic engineering studies
considering such aspects as traffic volumes, traffic speeds, intersection sight lines,
collision experience, etc., indicate that its usage is warranted. Without restricting the
intended usage, Yield Signs may be warranted in assigning right-of-way at locations
where one or more of the following conditions exist:

(a) on the minor road approach to an intersection where the safe vehicular approach
speed is greater than [5 km/h:

(b) where a fully developed acceleration lane is not provided atthe entrance ramp toan
expressway or a right-turn ramp at an at-grade intersection:

(c) within an intersection with a divided highway where a Stop Sign is installed at the
entrance to the first roadway and further control is necessary at the entrance to the
second roadway; and where the median width between the roadways is less than

30 m.

SPEED CONTROL

Speed Control signs shail indicate the maximum lawful speed under ideal conditions, or
minimum lawful speed under ideal conditions on the section‘ of roadway identified by
the signs.

During an introductory period following conversion to Metric Units, tab signs with
the legend “km/h” shall be placed below all speed control signs. (RB-7)

Speed Control signs shall be placed in accordance with the general specifications
for regulatory signs (Sections Al.15, Al.16, and Al.17)

“Maximum Speed Sign (RB-1)

thee awe tame.

The Maximum Speed sign shall indicate to road users the
maximum legal vehicle speed which is permitted on the road way
section indicated by the presence of the signs.

The maximum speed in kilometres per hour, as established
by law, is shown in large numerals in multiples of 10 km/h.

The sign shall be reflectorized or illuminated to show the
same shape and colour by night as by day,

60 x 75 cm
Lacation Of Maximum Speed Signs
Maximum Speed signs shall be located at the beginning and at the end of various speed
zones. The Maximum Speed sign shall be erected on provincial highways, in rural
districts, as well as at the entrance to a province and at boundaries of metropolitan
areas,
