Eccles, Kimberly A.; Hummer, Joseph E.. SAFETY EFFECTS OF FLUORESCENT YELLOW WARNING SIGNS AT HAZARDOUS SITES IN DAYLIGHT. Transportation Research Board. p. 3 11 February 2020閲覧. "The Problem Yellow warning signs are an important and abundant type of traffic control device. Yellow warning signs inform the motorist about potentially hazardous conditions on, or adjacent to, a highway. Yellow warning signs may prompt a driver to become more alert, exercise more caution, or reduce speed. Yellow warning signs are commonly used prior to changes in alignment, changes in cross section, intersections, signals, or STOP signs. Because they are relatively inexpensive, many engineers believe that installing warning signs is generally one of the most cost-effective safety countermeasures available."
