DES MOINES - Officials say high gas prices and the grim economy are factors in a drop in the number of people killed on Iowa roads in 2008.
Based on preliminary figures, state officials estimate between 410 to 415 people died in traffic accidents last year. That would be the third lowest since World War II.
The others are 2004, when 388 people died, and 2002, when 405 people were killed.
Scott Falb of the Iowa Department of Transportation says record-high gas prices and a national recession caused Iowans to drive less and to slow down. Falb says while people probably weren't intentionally being more careful, they were being more cautious in the way they drove to save money.
Iowa recorded its deadliest year for traffic deaths in 1970, when 912 people died.
