What is the question?
Often in a traffic stop when an officer suspects impairment, they will ask the question “on a scale of 1 to 10, 1 being sober and 10 being pass out drunk, how would you rate yourself”. Seems like a straight forward question, but is it really fair, and is there a right and wrong answer?
Police manipulate breath testing devices (breath alcohol machine) by controlling the way people blow into them. Usually, police officers tell a person taking an alcohol breath test to take a deep breath and to blow into the machine as long as possible. During the test the officers will encourage this by telling the test subject to “blow, blow, blow” until the person runs out of breath. The alcohol breath test results then produce a falsely high number.
The blow alcohol tester machines are designed to estimate your blood alcohol content or BAC by measuring your breath alcohol. To do this the machines must use certain assumptions about your temperature, blood particulate levels, and several other factors.
By far the most important factor is temperature. Henry’s Law says that the concentration of a substance contained in the gas found in the headspace over a liquid is directly proportional to the temperature at the point of exchange. In breath testing terms this means that the warmer your lungs are, the more alcohol will be in your breath, regardless of the concentration of alcohol in your blood.
For a law enforcement officer to stop you, they must have a “reasonable articulable suspicion” that criminal activity is underway. One issue that gives rise to being stopped is a little known requirement that motorists move over when they see emergency flashing lights on or adjacent to the highway.
You’re driving on the highway and see flashing lights what do you do? Well, it’s what you don’t do that could cost you.
In 2001, a law requiring motorists on Maine’s roadways to slow down and/or pull over for an emergency vehicle was implemented. Title 29-A §2054-9 the “Move Over” law requires the operator of a vehicle who is passing a stopped emergency vehicle using an emergency light, to use due regard to the safety and traffic conditions, requiring that the driver:
