The officer may request a blood sample from you when it is not possible or it is impractical to get a breath sample. Examples include a situation where there is no breath machine available, or you were in the hospital for a significant length of time so that a breath sample taken after your hospital visit would not be accurate. If the officer requests your permission for a blood sample, he or she must read a form that explains your rights and the consequences of refusing. This form is called “Implied Consent.”
The officer may usually only force you to submit a blood sample if you were involved in an accident where there was a fatality or serious bodily injury.
