The National Police Agency has drafted tougher measures to crack down on drunken driving, including plans to lower the minimum amount of alcohol that can be consumed before driving and to make it impossible to get a license again if a driver kills someone while under its influence.

The agency will solicit opinions from the public between Friday and Jan. 17, with an eye to putting the measures into force in June.

Drivers' licenses can currently be suspended if the driver's alcohol level is found to be at least 0.25 mg per liter of exhaled air, regardless of whether there was an accident.
