From 1999 to 2012, there were 4,479 motor vehicle accident (MVA)-related deaths among members of the U.S. Armed Forces. Of these, the single most common underlying cause of death was motorcycle accidents (n=1,134; 25.6%). Among active component service members during the 14-year surveillance period, the annual number (n=355) and rate (25.1 per 100,000 person-years[p-yrs]) of MVA-related deaths peaked in 2004. Since then, a steady downward trend followed and the 2012 number (n=184) and rate (13.2 per 100,000 p-yrs) were the lowest of the entire period. For members of the reserve component, the annual number of deaths peaked in 2005 (n=86), but the number in 2012 (n=22) was the lowest of the period. In 2012, the number (n=90) and rate of deaths (6.5 per 100,000 p-yrs) related to motorcycle accidents among active component service members almost equaled the number (n=94) and rate of deaths (6.7 per 100,000 p-yrs) from all other types of motor vehicle accidents combined. During the entire period, numbers of fatal motor vehicle accidents tended to be higher in the warmer months of the year. After 2009, motor vehicle accidents were no longer the leading, non-war- related cause of death among U.S. service members.
1999年至2012年期间，美国武装部队成员中有4479人死于与机动车事故（MVA）相关的事件。其中，最常见的单一潜在死亡原因是摩托车事故（n = 1134；25.6%）。在14年的监测期内，现役部队成员中与MVA相关的死亡年度数量（n = 355）和死亡率（每10万人年[人年]25.1例）在2004年达到峰值。自那时起，呈稳步下降趋势，2012年的数量（n = 184）和死亡率（每10万人年13.2例）是整个时期内最低的。对于后备役部队成员，死亡年度数量在2005年达到峰值（n = 86），但2012年的数量（n = 22）是该时期内最低的。2012年，现役部队成员中与摩托车事故相关的死亡数量（n = 90）和死亡率（每10万人年6.5例）几乎与所有其他类型机动车事故合并后的死亡数量（n = 94）和死亡率（每10万人年6.7例）相等。在整个时期内，致命机动车事故的数量在一年中较温暖的月份往往更高。2009年之后，机动车事故不再是美国军人中主要的非战争相关死亡原因。
