Cars should roll easily across a smooth floor or down a cardboard or wooden ramp propped up on stairs. If not, check that the wheels are free to turn (the wheels aren’t rubbing on the chassis and the axles aren’t rubbing on the bearings) and that the axles are parallel. Building a small fleet of these cars provides opportunities to race them, either for speed down a ramp or for distance from the base of the ramp to the far reaches of the classroom or gym. Add weights (fishing weights, metal washers, etc.) to see if the cars perform better. Measure and record each trial run. Record the best distance each team achieves by writing the team. | .

MfTSA Revised February 2012 2010 Motor Vehicle Crashes Overview In 2010 32 885 people died in motor vehicle traffic crashes in the United States the lowest number of fatalities since 1949 30 246 fatalities in 1949 see Figure 1 . This was a decline in the number of people killed from 33 883 in 2009 according to NHTSA s 2010 Fatality Analysis Reporting System FARS . In 2010 an estimated million people were injured in motor vehicle traffic crashes compared to million in 2009 according to NHTSA s National Automotive Sampling System NASS General Estimates System GES . This slight increase increase in the estimated number of people injured is not statistically significant from the number of people injured in crashes in 2009.

The overall injury rate remained the same from 2009 to 2010. The 2010 rates are based on VMT estimates from the Federal Highway Administration s FHWA August 2011 Traffic Volume Trends TVT . Overall 2010 VMT increased by percent from 2009 VMT from 2 953 501 million to 2 999 974 million. VMT data will be updated when FHWA releases the 2010 Annual Highway Statistics.
