According to the USA Today, 11 states now require all people convicted of first time DUI / Drunk Driving to install ignition interlock devices. The US Congress may take up this issue this fall that will mandate states require all people convicted of first time DUI / Drunk Driving to install the devices in order to receive Federal Highway Funds. Any state that does not meet this requirement risks losing Federal Highway Funds. Reportedly, if all states meet the requirement, then there will be nearly 1 million ignition interlock devices installed in the US each year. If each device costs… Read More

According to the American Beverage Institute, DUI / Drunk Driving checkpoints are costly and ineffective. Citing California statistics, in 2008, out of 1,000,000 motorists stopped at DUI checkpoints, only one-third of one percent were charged with DUI / Drunk Driving. On the other hand, publicizing the locations of DUI / Drunk Driving checkpoints may have a deterrent effect on drinking drivers who are aware of the checkpoints and their locations. I wonder if a study will be done that measures the amount of time each motorist is stopped and use those results in the analysis of whether or not to… Read More

Recently, the California Supreme Court held that competent evidence of variations between people’s breath alcohol levels and blood alcohol levels is admissible to show that breath tests results can overstate the actual blood alcohol level of a driver in DUI / Drunk Driving prosecutions. This scientific principal is called partition ratio variation which has been well documented in the scientific community for decades. This variation is caused by all breath testing machines being programmed to assume everyone has the same variation formula. In reality, this formula is only based on an average and does not take into account an individual’s… Read More

Many states are now requiring all driversconvictedofDUI / DWI / Drunk Driving to install ignition interlock devices. In 2005, New Mexico was the first state to requireinstallation ofignition interlock devicesfor all drivers convicted of DUI / DWI / Drunk Driving. Currently, there is a bill pending in the California legislature to fund a pilot program to require installation of ignition interlock devices for convicted drunk drivers in Los Angeles, Alameda and Sacramento counties. One of the difficulties of requiringconvicted drunk drivers to install ignition interlock devicesis that often times more than one person drives a vehicle belonging to a person… Read More

After checking for this 4th of Julyholiday weekendDUI / Drunk Driving checkpointlocations, I found most of the publicity suprisingly vague as to specific locations. What wasalso suprising is that many of the checkpoints will stop every driver that drives into a checkpoint in order to check for people who may beDUI,lack validdrivers’ licenses and possibly for possessingfireworks as well. Generally, the police are required to disclose the specific locations and not stop every driver in a DUI checkpoint. However, combining DUI / Drunk Driving checkpoints with fireworks and driver’s license checks, law enforcement may feel it can be lessvague in… Read More

The United States Supreme Court recently held that a defendant in a criminal case has the constitutional right to cross exam governmentchemists who analyze chemical substances when the government seeks to introduce into evidence the lab reports prepared by government crime labsto prove the substance is what the government says it is. Prior to this ruling and as it relates to DUI / DrunkDriving prosecutions, some statesallowed government lab analysisreports into evidencewithout the need to call the analyst to testify as to the lab report contents. However, in California, this ruling doesn’t change the admissibility of crime lab reports in… Read More

According to a report released on February 18, 2009, by the National Research Council of the National Academies of Science, Engineering and Medicine, the nation’s crime labs on the federal, state and local levels are rife with serious deficiencies including lacking practitioner and laboratory independence, standards, oversight and certification. The National Research Council called for the establishment of a wholly independent federal agency, the National Institute of Forensic Science to address the problems in the current science and system. As this relates to DUI / Drunk Driving defense, we experience a wide variation of policy, procedures and testimony from the… Read More
