The agency released its “most wanted list” on Wednesday, a laundry list of policies it would like implemented nationally. The list includes recommendations to reduce the current 0.08 blood alcohol content limit and outlaw all cell phone use while driving, even hands-free technology.

“When it comes to alcohol use, we know that impairment begins before a person’s BAC reaches 0.08 percent, the current legal limit in the United States,” the agency said. “In fact, by the time it reaches that level, the risk of a fatal crash has more than doubled. That is why states should lower BAC levels to 0.05— or even lower.”

The agency issued the recommendation while admitting that “the amount consumed and crash risk is not well understood.”
