The accused was charged with operating a motor vehicle with excess alcohol after being stopped at a RIDE program.
At trial, the defence argued that the presence of cell phones and police radios near the Intoxilyzer 8000C caused radio frequency interference (RFI), leading to a malfunction.
The court heard expert evidence on the machine's RFI safeguards but found no evidence that a malfunction actually occurred or that it would result in an artificially high reading.
The court concluded the defence's theory was speculative, failed to raise a reasonable doubt, and found the accused guilty.
