Nearly 8000 people have signed up to the Herald on Sunday's Two Drinks Max campaign.
As of Friday night, 7900 people had pledged never to drive after consuming more than two standard alcoholic drinks.
A street petition to boost the campaign will be held in the next fortnight, after members of Students Against Drink Driving postponed it yesterday due to pending school exams.
The campaign's aim is to make the roads safer and put pressure on the Government to lower the drink-drive limit.
Herald on Sunday editor editor Bryce Johns said the goal was to get 10,000 people to sign up.
"That will be a fantastic result. If the Government won't do the right thing, we'll at least have 10,000 people guaranteeing their ability to drive safely on the road."
The paper is printing the names of all who sign on.
