Party hosts, family and friends must stand up to drink-drivers this Christmas, says Road Safety Minister Liza Harvey.
"It's up to you to stop them," she said. "Take the keys from them, throw them in a cab and send them home."
Mrs Harvey yesterday launched an information pack on how to be a responsible party host.
"There's no excuse for drink-driving," she said.
"Everyone knows it's wrong. Every death at the hands of a drink-driver is 100 per cent preventable."
Stacy Dunbar, the mother of eight-month-old drink-driving victim Nate Dunbar, who died in January, spent 45 minutes discussing her case with Mrs Harvey.
They talked about changing the drink-driving culture in WA and the impact of road deaths on families.
A teenage relative of Mrs Harvey died in a high-speed freeway crash.
Mrs Dunbar is the face of The West Australian's Pledge For Nate campaign, which calls on people to promise not to drink and drive and to stop their friends drinking and driving.
About 6000 people have signed the pledge and tens of thousands more have watched Mrs Dunbar's heartbreaking video plea.
She said anyone considering drinking and driving should spend a day living her life, feeling her loss and pain, especially in the lead-up to Christmas.
The information pack includes tips such as keeping taxi phone numbers near the phone, appointing skippers at the start of the night, making sure bedding is available for people to stay overnight and doing your best to stop drinkers from driving.
People should serve their own drinks so they could keep track of how much they had had to drink.
