dc.description.abstract | In 2010, national fatal crash counts went down by 3.5%, following on the heels of substantial drops in 2008 and 2009. However, in Michigan, fatal crashes were down substantially in 2009, but up by nearly 8% in 2010. This report contains an in-depth look at the patterns associated with Michigan’s fatal crash increase in 2010. In particular, we present a time series analysis of fatal-crash trends over the last 40 years. In addition, we provide breakdowns of crash subcategories, focusing on alcohol and drug use by drivers, commercial vehicles, young and elderly drivers, motorcycles, and construction-zone crashes. Finally, we compare the pattern in Michigan to the patterns of fatal crashes for three other states. The primary result of these analyses is that 2009 was unusually low in fatal crashes and 2010 represents a return to normal numbers. That said, fatal-crash-involved drivers testing positive for blood THC have more than doubled in 2010. In addition, construction zone crashes have increased, though the base numbers are too low to determine whether the increase is significant. Motorcycle fatalities showed large increases in 2010, especially in collisions with other motor vehicles. In the multi-state comparison, the nearest state, Wisconsin, showed the same 2009 decrease and 2010 increase in total crashes, while more distant states of Idaho and Missouri showed steady decreases. These results are consistent with regional trends reported by NHTSA. The four states showed similar results with steady decreases in overall crashes and steady increases in drug-related fatal crashes. | en_US |
