What factors can affect a field sobriety test in Minnesota?

On Behalf of | Jan 12, 2026 | DWI

Police officers in Minnesota who suspect you might be driving under the influence might pull you over. If this happens, it is likely they will ask you to take part in a series of sobriety tests to make sure that you are sober and capable of driving.

These tests include the one-leg stand test, which requires you to balance yourself on one leg and count upwards from the number 1,000. Another test is the walk-and-turn test, where you will need to walk in a straight line, pivot on one foot and return. Last is the eye test, which is also known as the horizontal gaze nystagmus test. This tests your eyes’ ability to react and follow to moving objects. Though the court uses the results of these tests as evidence if you have a DWI charge, they are not completely foolproof and sometimes factors beyond your control can affect the results.

What might affect the results of a field sobriety test?

There are a total of three different field sobriety tests, each designed to measure a driver’s reflexes, ability to think as well as the coordination of their body. These tests are physically and mentally strenuous, making it difficult if the conditions are not ideal. Some of the factors that might affect the results of a field sobriety test include:

  • Police officer giving unclear or incorrect instructions
  • Officer adding non-standard tests
  • Uneven ground that might affect your balance
  • Nervousness and anxiety
  • Poor observation from the officer
  • External distractions such as bright lights and loud sounds
  • Injuries and disabilities, both mental and physical
  • Harsh weather
  • Old age

Failing these field sobriety tests can lead to a DWI charge. This can happen even if you did not consume any alcohol or other illegal substances before driving. It is important to be aware of the factors that might negatively affect the results of the test if you want to avoid a potential charge.

What to do if you are sober and get a DWI charge

If you gain a DWI charge despite refraining from alcohol, it is important to familiarize yourself with Minnesota’s DWI laws. Seeking guidance from a legal professional can help you learn your rights and understand complex legal procedures.
