Field Sobriety Tests are Risky

When a police officer pulls a driver over for suspicion of drunk driving, the driver will likely be subjected to one or more field sobriety tests to gauge the level of impairment. These tests use a variety of measures to help police officers determine a driver’s physical and cognitive abilities. A driver may be asked to perform certain tasks such as:

  • Walking a straight line
  • Standing on one leg
  • Touching the nose with the index finger
  • Counting the number of fingers raised by the officer
  • Taking a horizontal gaze nystagmus test
  • Taking a preliminary breath test (PBT)

Although these tests are usually difficult for most drunk drivers, many sober drivers can’t perform the required tasks. Sobriety field tests do not accurately gauge a person’s level of impairment well enough to warrant probable cause for arrest.

Under Minnesota law, drivers are not legally obligated to take field sobriety tests. Most drivers comply because they don’t know the law, or they’re trying to avoid a DWI arrest and conviction. Many people think they’re required to take a preliminary breath test (PBT) when they are pulled over. However, a PBT is performed on the scene using a hand-held device and is not required by law. In some cases, drivers who have been drinking take the PBT test out of fear of getting arrested, even if their alcohol levels are below the legal limit of .08. Drivers are only required to submit to chemical tests that measure BAC through a breathalyzer, blood, or urine test. These are normally performed at a hospital, police station, or jail.

Field sobriety tests, standardized by the National Highway Traffic Safety Administration, have been used by police officers for several decades. Studies show that the horizontal gaze nystagmus test used to track involuntary eye movement can register a false level of alcohol because of 40 different medical conditions, other than intoxication. Since field sobriety tests often have inaccurate results that may show probable cause for a DWI arrest, drivers should know they have a legal right to refuse the tests. A Minneapolis drunk driving lawyer often advises drivers to politely refuse field sobriety tests.

What to Do If You Have Been Charged with a Criminal Offense

What Happens If You Get a DWI While Riding a Scooter or E-Bike in Minneapolis?

Minnesota DWI laws apply to all types of motorized vehicles using the road. So, you may get arrested and charged with DWI while riding a scooter or E-bike if your blood alcohol concentration is 0.08 or more. The penalties for a DWI conviction may range from driver license suspension or revocation and fines to imprisonment. A conviction may also result in collateral consequences, including job loss and higher auto insurance premiums. A DWI lawyer can minimize the legal consequences or avoid them altogether. So, be sure to retain a lawyer immediately after you get arrested or charged for riding a scooter or e-bike while impaired.

Can a Criminal Record Impact New Charges in Minnesota?

People with prior convictions and facing new charges may wonder, “Can a criminal record impact new charges in Minnesota?” Having a criminal record can influence how the prosecution and court will handle your current charges. The court may deny your bail request or impose strict conditions. It may also impose harsh penalties. The prosecution, on the other hand, may be reluctant to give you a favorable plea deal if you have a prior conviction for a similar or related offense.
