Experts who have studied motor vehicle fatality trends said one reason for the dramatic decline is that people are reducing their nonessential driving first, which is often leisure driving at night or on weekends. That also happens to be riskier than daylight commuting on congested highways at lower speeds.
Teenage and elderly drivers — who also have higher accident rates — are more likely to feel the pinch of higher gas prices, and thus may be cutting back more than other drivers. Federal data also shows that driving declines have been more dramatic on rural roads, which have higher accident rates than urban highways.
And, some drivers are simply trying to save on gas by slowing down, which also decreases risk. "It could be that the safety benefits of driving slower are proportionately greater than the fuel economy benefits," Sivak said.
The steepness of the fatality decline underscores a point several experts have made recently — that raising the price of gas is more effective than almost any other means of reducing fatalities.
So does this mean the rise has been worth it?
