The crew were in Bathurst filming over race weekend, with their footage giving audiences a behind-the-scenes look at the relentless campaign against drink driving.

RBT has been on prime time TV for 10 years, and its popularity shows no signs of waning.

"We follow the HWP guys doing their normal duties,” Sergeant Phil Green from the Public Affairs branch said.

And they film everything.

"In a public place, no one can stop you filming," he said.

Three different crews film 10 to 12 weeks a year, which provides enough footage for the show for a year.

Sgt Green said the show was having a huge impact.

"We sometimes have trouble finding drink drivers, so the message is definitely getting out there."

Why it continues to have such interest is anyone’s guess, with even Sgt Green at a loss to explain its ever-increasing popularity.

"I've always wondered why it is so popular watching someone get breath-tested.”

Producer Craig Gaudion said he thinks it’s because it's family viewing.

“The kids love waiting for the driver’s reading to come up; it's like working out the lotto numbers.”
