Guillermо, а truck driver, is tоld by his bоss, Rаymond, to quickly deliver а load of steel and to get to the location within an hour regardless.

Soon thereafter, Guillermo was stopped by a highway patrol officer and issued a citation for both speeding and reckless driving. When he went to court, Guillermo told the judge that he should be found not guilty because he was only acting upon orders of his boss, Raymond. Is Guillermo correct?
