Regulatory Signs
Definition: Regulatory signs are used to inform road users of selected traffic laws or regulations and indicate the applicability of the legal requirements.
Primary Purpose: To instruct drivers on what they must or must not do at a specific location.
Identification by Shape:
Octagon: Exclusively used for "Stop" signs.
Equilateral Triangle (Pointed Down): Exclusively used for "Yield" signs.
Vertical Rectangle: Typically used for specific instructions like speed limits, lane controls, and movement prohibitions (e.g., "No Left Turn").
Square: Often used for regulatory markers like "Do Not Enter."
Horizontal Rectangle: Occasionally used for one-way signs.
Identification by Color:
Red: Indicates a prohibition or a requirement to stop/yield.
White: Used as a background for regulatory signs to indicate a law or rule.
Black: Used for the lettering or symbols on the white background.
Warning Signs
Definition: Warning signs alert drivers to conditions which are potentially hazardous on or adjacent to the roadway.
Primary Purpose: To call attention to unexpected conditions and to situations that might not be readily apparent to road users.
Identification by Shape:
Diamond: The standard shape for general warnings (e.g., curves, intersections, deer crossings).
Pennant (Sideways Isosceles Triangle): Specifically used to mark the beginning of a "No Passing Zone."
Pentagon (Pointed Up): Specifically used to indicate school zones and school crossings.
Circle: Used for advance warning of a railroad crossing.
X-Shape (Crossbuck): Used specifically at the location of railroad tracks.
Identification by Color:
Yellow: The standard background color for general warning messages.
Fluorescent Yellow-Green: Often used for high-emphasis warnings involving pedestrians, bicycles, or schools.
Orange: Exclusively used for temporary traffic control, construction, and maintenance zones.
Guide and Information Signs
Definition: Guide signs provide directional and identification information so that drivers can reach their destinations in the most simple and direct way possible.
Primary Purpose: To assist road users with route navigation, distances, and location-based services.
Identification by Shape:
Horizontal Rectangle: The most common shape for providing directional information and service details.
Shield: Used specifically for route markers (e.g., Interstate, U.S. Routes, State Highways).
Identification by Color:
Green: Indicates directional guidance, such as exits, distances, and mile markers.
Blue: Indicates traveler services, such as food, gas, lodging, and medical facilities.
Brown: Indicates public recreation areas, cultural sites, and points of historical interest.
Lane Markings
Purpose: Pavement markings are used to guide and separate traffic. They have the same force of law as signs.
Color Conventions:
Yellow Lines: Separate traffic moving in opposite directions.
White Lines: Separate traffic moving in the same direction.
Pattern Types:
Broken Lines: Indicate that passing or lane changing is permitted if it is safe to do so.
Solid Lines: Indicate that passing or changing lanes is discouraged or prohibited.
Double Solid Lines: Strictly prohibit passing in either direction.
Rules for Round-A-Bouts
Definition: A round-a-bout (roundabout) is a circular intersection where traffic circulates around a central island.
Yielding Rules: Drivers approaching a roundabout must yield the right-of-way to traffic already circulating within the intersection. Traffic within the circle has the priority.
Direction of Travel: Vehicles must always travel in a counter-clockwise direction around the central island.
Entry and Exit:
Drivers should reduce speed and choose the appropriate lane based on their intended exit before entering.
Turn signals should be used when intending to exit the roundabout to inform other drivers and pedestrians.
Prohibitions: Drivers should never stop within the roundabout or attempt to pass large vehicles (like trucks or buses) that may need extra space to navigate the curve.
