  • The increased use of retroreflective materials holds great promise for enhancing the conspicuity of emergency vehicles.
  • Both visibility and recognition are important facets of emergency vehicle conspicuity.
  • The use of contrasting colors can assist drivers with locating a hazard amid the visual clutter of the roadway.
  • Fluorescent colors (especially fluorescent yellow-green and orange) offer higher visibility during daylight hours.
  • There is limited scientific evidence that drivers are “drawn into” highly-visible emergency vehicles.
  • It is theoretically possible to “over-do” the use of retroreflective materials and interfere with drivers’ ability to recognize other hazards.
  • Effectiveness of the “Battenburg” pattern in the UK appears primarily related to its association with police vehicles in that country.
