We have a word of warning for travelers this Labor Day weekend -- local law enforcement will be out in full force checking for DUIs.

Sullivan County and Jefferson County have been chosen to be part of Tennessee Highway Patrol's "no refusal" campaign.

The counties were selected after seeing a recent increase in highway fatalities this year.

The campaign will mean more traffic stops for drivers and a legal obligation to allow for a blood test if officers find probable cause for a DUI charge.

Officers would have to request a search warrant for a judge if someone refused the test, as part of new legislation from the General Assembly.

"DUIs, they kill people on our highways. That's what this whole weekend enforcement and ‘no refusal’ weekend is going to be all about. We're wanting to save lives," said Major Dean Hurley with THP.

THP officers also told us last year there were ten fatalities during Labor Day weekend. This year they are hoping for zero.
