In the fight against drunk driving, safety regulators and law enforcement work tirelessly to implement new measures that will aid in DUI prosecution. Many of these new measures are based in technological advancements, such as lasers to detect the presence of alcohol in the cabin air of a vehicle.
As a driver in Orange County, it’s important to understand what technology may be used against you now and in the future.
Alcohol-Sensing Flashlights
These special flashlights contain sensors that can detect the presence
of alcohol on a driver's breath when used within about one foot of
the driver. The flashlight can then indicate whether alcohol is present.
Though the results of such a test are currently inadmissible as evidence
in court, officers may use them to determine whether
field sobriety tests should be performed.
Lasers
Researchers in Poland released the results of a study that used a laser
to detect alcohol in vehicles' cabins. The laser is an off-site device
placed on the side of the road and used to detect alcohol levels in passing
vehicles. The data of such tests would be sent to waiting law enforcement
officers down the road, who would pull over any potential drunk drivers
to perform standard tests to determine possible intoxication.
Breath Tests
A current standard in DUI testing,
breathalyzer tests are used to measure the level of alcohol in a driver's breath. This
type of device requires the driver to submit a breath sample by breathing
into a tube.
The device then analyzes the breath sample for the presence of alcohol, calculating the driver's blood alcohol concentration (BAC). The results of breath tests are admissible in court and provide the foundation of the prosecution's case against a driver.
Blood Tests
Considered more reliable than breath tests,
blood tests require a blood sample from a driver that is then tested for alcohol levels.
Blood samples must be drawn, handled and stored properly to preserve the
accuracy of this type of evidence, which is admissible in court.
Mishandling or improper storage or testing of blood samples may render them unusable by the prosecution, making it important for a defense attorney to conduct an independent test and analysis of the manner in which such a sample was taken and handled.
Ignition Interlock Devices
Ignition Interlock Devices (IIDs) are installed in the vehicles of repeat
DUI offenders to prevent future drunk driving. These are small breath
test devices that do not allow a vehicle to start if a driver submits
a sample tainted with alcohol.
A breath sample is required to start the vehicle and may also be required at intervals while the vehicle is in motion. If a driver provides an unacceptable breath sample while the vehicle is in motion, the horn may honk and lights may flash to alert law enforcement.
Anti-DUI Devices in New Vehicles
There is even new technology being considered to prevent drunk driving
in the first place. Concept cars have been presented that include sensors
in the cabin, which would be used to detect a driver's BAC and would
prevent the vehicle from starting if it is .08% or greater.
One system in such a vehicle uses a touch-sensitive sensor in the steering wheel and an infrared light. The other tests the driver's breath using the cabin air rather than requiring the driver to breath into a tube or other device.
