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.
