Houston we have a problem:

All Field Sobriety Tests are VOLUNTARY, NOBODY is ever required to take one. Nor is anybody required to blow in a hand held device in the field, it also is VOLUNTARY.

Only Drug and Alcohol testing taken in a controlled environment(at the station, with a licensed,calibrated machine or Blood Test taken by a Licensed Physician or Practitioner AFTER ARREST are admissible.

Already covered by the article: '“I think it would definitely be helpful as a roadside test, but just like with alcohol, you still need to bring someone back to headquarters and get results you can prosecute them on,” said Southold Police Chief Martin Flatley. [...] “But any tool like that, that helps us to identify an impairment, is useful.”'

“Nor is anybody required to blow in a hand held device in the field, it also is VOLUNTARY.”

Yup, totally voluntary. You are free to refuse and have your drivers license revoked for a year, and be hauled to a hospital to have blood drawn at your expense.

But you’re right, it’s your choice. That is the law in MI.

Driving licenses in California are a privilege, not an absolute right. One condition is agreement to allow sobriety tests.

Refuse a test, lose your license. that simple.

Licenses can be revoked by the courts, by the licensing department or both.

In addition to alcohol, impairment can come via prescription drugs, cocaine, heroin, amphetamines, peyote, marijuana, etc.

I am not aware of the scientific research to prove the levels of impairment metrics, test procedures, etc.
