DUI, Ignition Interlock, and The State Legislature

An ignition interlock is required to obtain a restricted driver's license if you have been convicted of a DUI charge in Tennessee. In the initial implementation of the ignition interlock device, I was in favor of it's use. It allowed those with multiple DUI convictions to get a restricted license rather than drive under the radar. It also removed the geographical and time restrictions of driving. It also encouraged those who submit to the test to be more aware of their drinking habits.


As of July 2016, the use of the ignition interlock has amped up. In part due to the work of the industry and the Tennessee State Legislature.

Three big changes happened. First. you must have an ignition interlock installed even if you elect not to get a restricted driver's license. Some folks who live in downtown Nashville may use alternative transportation during the one year suspension. Now, they will have to install an ignition interlock device(IID) when then get their regular license. Secondly, one has to have 120 days of negative tests before the IID device can be removed from their car. One positive test starts the clock back to day one. It is possible you could have the device on your car. I think the IID folks want to keep a IID on your car for as long as possible at $90.00 per month. Finally, one was allowed to drive a company owned vehicle without an interlock device if the company knew of his conviction. Now folks lose their jobs because they can't drive the parts truck or the company van.

Who monitors the IID ? The provider who is making $90.00 a month. How do you double check or contest their work ? Who knows ? You get bogged down by the bureaucracy of the Tennessee Department of Safety. Take a look at Tennessee Code annotated 55-10-425.Here is a link to the new statute. I wonder who drafted it.

Maybe it is too much of a good thing.

Twitter and DUI Checkpoints

What does Twitter and DUI checkpoints have in common ? Apparently , Twitter is being is being used to warn DUI drivers of the location of DUI checkpoints around the country. USA Today"s Chris Woodyard  reported that police around the country will be setting up DUI sobriety checkpoints or roadblocks in an effort to arrest DUI drivers.The police are complaining that Twitters are posting tweets of the location of the DUI checkpoints.

I have to confess that I thought Twitter was just a novelty even when I signed up.Now , Fresno , Ca. police reports it is a commonplace occurrence that drivers are tweeting so fellow drivers can avoid a DUI roadblock.One police officer admitted that his daughter send him texts of the locations of the checkpoints.

There are several Tennessee court cases that address the legality of DUI checkpoints and roadblocks.One requirement is advance notict of the roadblock.Normally, the police have to make an annoucemnet of the location and duration of the DUI roadblock.If the police do not comply with the requirements the DUI arrest may not be valid.

I will try to post the locations on Twitter if I become aware of them. You can follow me at www.Twitter.com/RobMckinney
