Effects On Traffic
AMBER alerts are often displayed on electronic message signs. The Federal Highway Administration has instructed states to display AMBER alerts on highway signs sparingly, citing safety concerns from distracted drivers and the negative impacts of traffic congestion.
Many states have policies in place that limit the use of AMBER alerts on freeway signs. In Los Angeles, an AMBER alert issued in October 2002 that was displayed on area freeway signs caused significant traffic congestion. As a result, the California Highway Patrol elected not to display the alerts during rush hour, citing safety concerns. The state of Wisconsin only displays AMBER alerts on freeway signs if it is deemed appropriate by the transportation department and a public safety agency. AMBER alerts do not preempt messages related to traffic safety.

Famous quotes containing the words effects and/or traffic:
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
“To treat a “big” subject in the intensely summarized fashion demanded by an evening’s traffic of the stage when the evening, freely clipped at each end, is reduced to two hours and a half, is a feat of which the difficulty looms large.”
—Henry James (1843–1916)
