Accordingly, in Minnesota, where there was no accident, it is most advisable to take the test. On the other hand, if you were involved in a serious accident, it may be advisable not to take the test and endure the revocation rather than provide evidence of a possible criminal vehicular operation. In Minnesota, even a first time DWI could get a 30-day jail sentence if the test exceeds .20. If you are a first time DWI and over .20, it may be advisable to refuse the test. Your revocation would last a year versus 180 days for the .20, but there is no 30 days in jail.
Physical control can mean sitting in a car, even without the keys in the ignition.
Also, the vehicle does not have to be a car. DWI-related offenses can apply to farm tractors or boats. If not, the resulting evidence is inadmissible by operation of the United States Constitution and the Minnesota Constitution, which protect us against unreasonable searches and seizures. Exercise your right to counsel before making your decision on chemical testing. The right to counsel is extremely important.
