Used in advance of a substandard curve or a curve that may not be evident to the motorist in the course of his travel along a reasonable straight section of the road.
Curve Sign (W1-3)
- Generally used where sight distance on the approach to an intersection is less than the safe stopping distance or where drivers may have difficulty appreciating the presence of the intersection ahead;
- Generally shall not be used where STOP, GIVE WAY, or traffic signals are installed;
- Used in advance of an intersection where 2 roads cross at a common point;
- This sign shall not be used on a side road to a controlled intersection.
CROSS ROAD SIGN (W2-1)

- Less than that of the approach pavement regardless of width.

Lane Lines
Types of Barrier Lines
- DOUBLE UNBROKEN YELLOW LINE - used only where overtaking from both directions of the road and all crossing movements are prohibited.
- SINGLE UNBROKEN YELLOW LINE - used where overtaking from both directions of the road is prohibited; however, crossing movements are permitted.

Used to delineate the edge of the travelled way to distinguish it from the shoulder area.
Edge Lines
Used to guide traffic safely past obstructions on roadways such as islands, median strips, bridge piers, or to indicate changes in the width of the traveled portion of the roadway and an increase or reduction in traffic lanes.
Transitional Lines
Should be placed across the appropriate portion of the roadway at positions where vehicles are required to stop in compliance with a stop sign, traffic signals, or any other legal requirement.
Stop Lines
Markings consisting of two adjacent broken white lines across the carriageway at which the drivers must give way to all traffic in accordance with R1-2 (Give Way Sign).
