Overall, 40 percent of crashes in the United States occur at intersections; a total of 57 percent of fatalities from 1997–2004 occurred at stop-controlled intersections, of which 61 percent occurred in rural areas. Factors believed to contribute to these incidents include inadequate surveillance, failure to obey/yield, driver inattention, and speed
