National Safety Council says the number is up 14 percent from four years ago.
The National Safety Council estimates that 438 people will be killed in car accidents in the United States over the Labor Day holiday period in 2016.

The National Transportation Safety Board will be getting a new boss, as the current head has announced she'll be stepping down. Deborah Hersman had a controversial tenure as head of the NTSB, strongly criticizing efforts in automotive safety.
According to an annual report published by the National Safety Council, there were 39,800 deaths last year related to motor vehicles in 2008. That's an 8% improvement over the previous year, and it's not entirely due to fewer miles driven, as the ratio of deaths per vehicle miles driven has also dropped.
