Section 3: Intersections
Introduction
Advisory zones may be posted at intersections such as traffic
circles designed for an operating speed less than the speed of the
approaches, and intersections with restricted sight distances that require
a reduction in speed for safe operation.
View Obstructions
For intersections having view obstructions, trial runs should
be conducted to determine the safe and reasonable speed for the
area. This speed may be posted as an advisory speed below a warning
sign to warn motorists of the limited sight distance.
