Accused was observed by an OPP officer backing up out of a ditch. When the accused approached the officer the officer noticed him unsteady on his feet, speech slured, and his eyes glassy. The officer then formed the opinion that his ability to operate a motor vehicle was impaired by alcohol. He was placed under arrest cautioned and the officer demanded a breath sample. When the accused arrived at the staion he took 15-20 seconds to complete the first breath test, and 15-20 seconds to complete the second test.
