refusing to test
Can I refuse to submit to a test?
tests
There are two types of tests used in drunk driving cases; field sobriety tests and chemical tests.
field sobriety tests
Field sobriety tests are tests conducted "in the field" after police stop a person whom they suspect of driving while under the influence. Typical field tests include standing on one foot, walking a straight line and turning around to walk back (walking heel-to-toe), touching a finger to your nose, and similar tests created by police over the years to "assumedly" test for sobriety.
You can refuse to take a field sobriety test, but I wouldn't recommend it. If you refuse to submit to a field sobriety test, that refusal alone is probable cause for an arrest for OWI - operating while under the influence.
chemical tests
Chemical testing, better known as blood draws or blood tests, are conducted at a hospital.
Breath tests, or tests conducted with an intoximeter (previously known as a breathalyzer) are conducted at a police station, as well as in the field with portable breath testing machines.
