Tens of thousands of law enforcement officers across the United States are on heightened alert for impaired drivers over the holiday period.

The US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has announced the high-visibility enforcement campaigns Drive Sober or Get Pulled Over and If You Feel Different, You Drive Different – Drive High Get a DUI.

NHTSA and traffic safety stakeholders will also educate the public on the risks of marijuana-impaired driving, a need highlighted by the results of NHTSA’s 2013-14 National Roadside Survey which showed an increase in THC-positive drivers.

“Almost everyone knows that driving drunk is dangerous, puts lives at risk, and can get you a DUI – but there isn’t the same awareness for marijuana-impaired driving,” said James Owens, NHTSA’s Acting Administrator.

“At NHTSA, we are working hard to raise awareness among the driving public that driving impaired by drugs or alcohol is dangerous and illegal in every state.”

The campaigns run until 1 January 2020.
