Wisconsin just finished its safest September for traffic deaths since World War II.
Fifty people were killed in crashes throughout the state last month. That's down from 82 last September.
The Department of Transportation says drivers have been slowing down and driving less due to the high gas prices.
Safety chief Dennis Hughes says motorists deserve a lot of the credit for "saving their own lives and the lives of others."
For the year as a whole, Wisconsin traffic deaths are down 20 percent from the previous year.
From January through September, 453 people died on the roads. That includes 67 motorcyclists, 34 pedestrians and nine bicyclists.
Fatalities dropped in every month except August, when 83 people were killed. That total is up from 66 the previous August.
