Since the beginning of their no refusal crackdown on drunk driving began on Friday, Austin police arrested 70 people for driving under the influence.
23 people were arrested Friday, 31 on Saturday, and 16 on Sunday.
The no refusal initiative runs through Monday.
In a no refusal weekend police will seek a search warrant for suspects who do not consent to a blood draw to check for alcohol levels.
In 2013 Austin police arrested 95 people over Labor Day weekend.
