ID=14518165(WBIR) Law enforcement officials are planning increased enforcement over Labor Day weekend to keep the roads safe.

The Tennessee Highway Patrol announced Sunday it will hold several "No refusal" checkpoints between Friday August 29 and Monday September 1.

The state's no refusal law allows authorities to get search warrants for blood samples if they suspect a driver is impaired.

THP will conduct "no refusal" checkpoints in Union County, Hamilton and Marion, Montgomery, Shelby, Hawkins, Smith, Maury, and Hardin County.

Troopers will also hold other checkpoints to check drivers' licenses and seat belts. In addition, THP is planning saturation patrols and bar and tavern checks.

During last year's Labor Day weekend, THP said 16 people died in vehicle crashes in Tennessee. Alcohol was involved in six of those fatal incidents.

Preliminary figures show while the number of crashes involving alcohol is lower so far this year compared to 2013, the number of DUI arrests is way up.

There have been 3,981 crashes involving alcohol-impaired drivers in Tennessee from the start of this year through August 15. In 2013, there had been 4,320 crashes already at this time of the year.

Meanwhile, troopers have seen a 34% increase this year in the number of people arrested for impaired driving.

THP said troopers arrested 5,310 individuals so far this year for impaired driving. In 2013, the number of arrests made during that time was 3,973.
