Side comment - may people due to physical limitations, are unable to pass a field sobriety test. Many with brain injuries, hip surgeries, depth perception, etc have such difficulties. There should be some means where a LEO can be informed that there are physical impairments involved with the driver.
Just telling a cop that you are physically impaired due to injury or surgery (but not disabled) does not seem to work. Fortunately for me, I requested a breathalyzer. The cop had to get another LEO there because he did not have the kit in his car. Before the breathalyzer, the cop was dead set that I was DUI cause I could not walk a straight line. The fact that I have a hip injury did not sink into his reality.
That’s Funny!!, I couldn’t pass the test now on my Best Day if I had to and I would NEVER EVER take a Field Sobriety test because it is Voluntary and it’s only purpose is to validate the bullshit reason they pulled you over for.
