Denver Breath & Blood Test Defense
Get the Help of Our Denver DUI Attorney - Call (303) 720-7280
When facing a DUI charge in Colorado, the prosecution's entire case
against the defendant hinges on the strength of evidence; namely, that
the defendant's BAC level was higher than the legal limit at the time
of the traffic stop. There are two types of chemical tests used to determine
a driver’s BAC level: a breath test and a blood test. If you have
been arrested for drunk driving after failing either of these tests, it
is important to understand that you may still have the chance to fight
a criminal conviction.
Can I Refuse a BAC Test?
Under Colorado law, you are required to take a breath or blood test if
you’ve been arrested for a DUI. The test must be administered within
2 hours of when you were last behind the wheel. By refusing to take the
test, the state can suspend your license – 12 months for the first
offense, 24 months for the second offense, and 36 months for the third offense.
Understanding the Breath Test
One of the most common forms of measuring blood alcohol concentration is
the use of a device called a breathalyzer. The breathalyzer is able to
gauge the amount of alcohol in the bloodstream through the air being exhaled.
Although it is only one of the methods of measuring BAC, it is highly
favored by police officers for the use of DUI stops. This is due to the
usability and portability of the device, which is a small instrument,
about the size of an old tape recorder.
The weakness of breath tests lies in the technology's science. When
a prosecution's entire case is built upon the results of a breath
Denver DUI attorney has the ability to scrutinize possible factors that could contribute to
a false or inaccurate reading.
These factors include:
- The officer wasn’t properly trained on how to use the breathalyzer machine
- The officer wasn’t properly trained on how to administer the test
- The officer made a mistake when administering the test
- The machine wasn’t calibrated correctly
- Machine errors, defects, or malfunctions
- Radio frequency interference
Information on Blood Tests
A blood test is conducted by drawing a sample of the driver’s blood,
which is tested to determine the amount of ethanol alcohol in the body.
Like a breath test, blood tests are not immune to inaccuracies and errors.
Although blood tests are arguably more accurate than breath tests, there
are still a number of factors that could cause the results of a blood
test to be inaccurate, such as:
- Contaminated testing equipment
- Broken or defective testing equipment
- Too much time elapsed between arrest and testing
- Technician error
One thing to understand is that when it comes to blood tests, it is extremely
difficult to track the chain of custody, as the tests are very extensive
and require a lot of human involvement. Human error is not uncommon and
can often be used as grounds to get the tests dismissed as proper evidence.
