Standard orange flags and flashing warning lights are important tools used to enhance the visibility of traffic signs and alert drivers to potential hazards. When used in conjunction with signs, these attention-grabbing devices must not block the sign face.

Proper Usage

Orange flags and flashing warning lights serve to draw attention to important traffic signs, especially in areas with construction, road work, or other temporary hazards. They are typically mounted above or beside the sign to increase its visibility without obstructing the message.

Placement Guidelines

  • Flags should be oriented at a 45-degree angle to the vertical
  • Flashing lights should be positioned to avoid glare or distraction
  • Both flags and lights must be securely attached to prevent movement

It's crucial to ensure that these devices do not obscure any part of the sign face. Blocking the sign's message defeats the purpose of using attention-grabbing devices and can lead to confusion or missed information for drivers.

Effectiveness

When properly implemented, orange flags and flashing lights can significantly improve driver awareness and compliance with traffic signs. They are particularly useful in the following situations:

  • Temporary construction zones
  • Areas with recent changes in traffic patterns
  • High-risk intersections or road segments
  • Locations with a history of accidents or near-misses

Maintenance

Regular maintenance is essential to ensure the continued effectiveness of these safety devices:

  • Replace torn or faded flags promptly
  • Check and replace batteries in flashing lights as needed
  • Clean signs and auxiliary devices to maintain visibility
  • Remove flags and lights when no longer necessary to prevent desensitization

By following these guidelines, traffic safety professionals can effectively use standard orange flags and flashing warning lights to enhance road safety without compromising the clarity of important traffic signs.
