I thought I would show everyone one what a SCRAM device looks like on Lindsay Lohan. Ms. Lohan was ordered to wear a Scram device when she failed to show up to court in California. I expect the SCRAM device to be used more often in Tennessee DUI cases by the courts. It works much like a breath test. The device senses alcohol from perspiration of the skin. Once it detects alcohol, it sends a result to the monitoring agency. The accused could be forced to wear it as a condition of probation or bond release.
