tick marks the Massachusetts share. Bars are shares of fatal crashes (alcohol, speeding, darkness, rural) or of people killed (pedestrians, motorcyclists, unrestrained occupants) over the ten-year window.

"Alcohol" counts crashes where police reported at least one driver as drinking (FARS DR_DRINK), not the BAC-based alcohol-impaired measure NHTSA publishes separately. "Speeding" counts crashes with a driver coded as racing, exceeding the limit or too fast for conditions. Details in the methodology. Factor pages: alcohol, speeding, pedestrians, motorcycles, unrestrained occupants.
