Each year, the Insurance Research Council, an industry group, estimates the number of uninsured drivers, by state.
The IRC estimates that in 2009 -- there's a lag time in the data -- roughly 1 out of every 7 drivers on the road has no insurance coverage. That's a slight improvement from the previous year, when the recession is believed to have led to a spike in the number of uninsured motorists.
The highest number of uninsured motorists, the group says, is in Mississippi (an astounding 28 percent), followed by New Mexico (26 percent) and a three-way tie between Tennessee, Oklahoma and Florida (all at 24 percent). Washington comes in at 16 percent, along with states like Indiana, Arkansas, Ohio and Georgia. Oregon and Idaho are among the lowest in the country, at 10 percent and 8 percent.
