Figure 4. Intersection Layout Illustrating Concepts of Clarify and Simplify

Full size image of Figure 4.

This diagram shows the approach to an intersection, including the correct distances for sign placement. At the southern most point of the approach is a diamond-shaped yellow sign with a red pentagram and an arrow pointing up, indicating a stop sign ahead. Below the stop ahead sign is a placard with the name of the upcoming cross-street. A notation on the diagram indicates users should see Table 2C-4 for the correct distance from the intersection that the sign should be placed. A second notation indicates users should see section 2C-29 for application of W3-1.

The next sign an approaching driver should see is an indicator that the intersection is a junction with State Route 46. A label indicates that the distance from the stop ahead warning sign and the junction ahead sign should be not less than 60 m (200 ft).

After the junction ahead sign, there is signage indicating that the through driver will continue north on Route 15 and the left turning driver will be traveling west on route 8. A label indicates that the distance from the junction ahead sign to the route 8 west and route 15 north sign should be not less than 60 m (200 ft).

After the route sign, a green sign indicates that a left turn (on route 8 west) will take travelers to the town of Newport and a right turn (on State route 46 east) will take them to Greenville. A label indicates that the distance from the route 8 west and route 15 north signs to the green sign with the town names should be not less than 60 m (200 ft).

The next sign on the approach is marked optional. This is a sign indicating that the road divides into two lanes: a left turn only lane and a right lane for drivers either turning right or proceeding straight through the intersection. A label indicates that the distance from the green sign with the town names to the optional sign should be not less than 60 m (200 ft).

The approach lane diverges into two lanes after this sign for an unidentified distance to the intersection. At the intersection, adjacent to the stop bar, is a STOP sign.
