I suppose it depends on what state you are from, but just generally reading some of them and the severity of the traffic violation, it would appear that voluntarily is not the rule as opposed to the exception???

Illinois --Any Traffic Arrest is Sufficient

625 ILCS 5/11-501.6 (a) Any person who drives or is in actual control of a motor vehicle upon the public highways of this State and who has been involved in a personal injury or fatal motor vehicle accident, shall be deemed to have given consent to a breath test using a portable device as approved by the Department of State Police or to a chemical test or tests of blood, breath, or urine for the purpose of determining the content of alcohol, other drug or drugs, or intoxicating compound or compounds of such person's blood if arrested as evidenced by the issuance of a Uniform Traffic Ticket for any violation of the Illinois Vehicle Code or a similar provision of a local ordinance, with the exception of equipment violations contained in Chapter 12 of this Code, or similar provisions of local ordinances. The test or tests shall be administered at the direction of the arresting officer. The law enforcement agency employing the officer shall designate which of the aforesaid tests shall be administered. A urine test may be administered even after a blood or breath test or both has been administered. Compliance with this Section does not relieve such person from the requirements of Section 11-501.1 of this Code.

So from the looks of it, each incident will determine what tests will be taken and how "Voluntarily/Non-Voluntarily".

Here in Canada, it's different, back in 79 I refused the breathalyser (I had 3 beers, but had just left the tavern, so not sure about the test, and I don't trust cops.) I automatically lost my license for 6 Months, that was it.(refusal was admission of guilt), now if you are involved in an accident and taken to a hospital, they will take a blood sample.

What happens if a person refuses to give the police a breath sample?

A police officer can demand that a driver provide a breath sample on an "approved screening device" when the police officer has a reasonable suspicion that the person has alcohol in his or her body. The approved screening device test is usually done at the roadside.

A police officer can demand that a driver provide a breath sample on an "approved instrument" when the police officer has reasonable grounds to believe that the person has committed an impaired driving offence or was driving while over the legal limit. The approved instrument test is usually given at the police station.

A person who refuses to give a breath sample when asked, and does not have a legal reason for refusing, can be convicted of the offence of refusing to provide a breath sample. The punishment for this criminal offence is the same as the punishment for the offence of driving while impaired.

The police can ask a person who is unable to provide a breath sample because of an injury or physical problem to provide a blood sample. A doctor or other qualified medical professional will take the blood sample. Refusing to provide a blood sample is also a criminal offence.
Note: that in both cases refusal is considered an admission of guilt, and the punishment is the same if not more severe....
