Tennessee law enforcement officials are intensifying their crackdown on drunk driving with the state's first ever "no refusal" campaign.
The no refusal measure passed during the recent legislature and Governor Haslam signed it in May.
It allows judges to compel blood tests for people arrested on drunken driving charges.
The no refusal enforcement period kicks of Tuesday and runs through Sunday.
The campaign coincides with the state's Fourth of July enforcement period, which runs Wednesday through Sunday.
