The Secure Continuous Remote Alcohol Monitor better known as SCRAM has
been become a very popular device across the country. In Houston, they
are used in
DWI cases when the person informs the court that they do not have a vehicle to install
the interlock device. There are over 15,000 units being used today. Harris
County Judges have started using it as a condition to a person's DWI
probation . An anklet with a GPS is due out next month. As a Houston DWI
Lawyer I anticipate that our courts will be using them more often in the future.
Despite the popularity SCRAM devices are susceptible to false positive
readings and malfunctions. Among other things, baked goods like raisin
bread and sourdough English muffins can cause the body to produce its
own alcohol. And like any computer-based device, the Scram can malfunction.
The buildup of sweat and dirt on the anklet has been known to provide
an incorrect tampering reading. When using these devices with more regularity
the courts should be also aware that like most machines it is not flawless.
