Imagine you are driving down a busy street. You are following the laws, driving responsibly, and you are not impaired.
Suddenly, a car hits you from behind. You bang your head off the steering wheel, and now you are feeling strange. When the officers arrive, they believe you are acting unusually. They force you to undergo Standard Field Sobriety Tests. They determine you failed the tests and arrest you for drunk driving.
Across the United States, drivers whom officers believe to be impaired undergo Standard Field Sobriety Tests (SFST). These tests test a person’s ability to maintain balance, follow instructions, and concentrate and remember.
While there are many issues with these tests, one of their major flaws is they can be heavily swayed by a person’s physical or medical condition.
Common Concussion Symptoms
According to the Centers for Disease Control and Prevention, common concussion symptoms include nausea and vomiting, dizziness, difficulty thinking clearly, unusual behavior, dilated pupils, difficulty remembering new information, balance problems, slurred speech, and, in severe cases, a loss of consciousness.

Meanwhile, common symptoms of alcohol intoxication include confusion or unusual behavior, nausea and vomiting, balance problems, slurred speech, dilated pupils, memory problems, and, in severe cases, loss of consciousness.
Going back to the previous hypothetical, the driver of the vehicle sustained a concussion from hitting their head on the steering wheel. Due to this head trauma, the driver showed multiple common concussion symptoms.
However, officers misconstrued this as evidence of alcohol intoxication, leading them to arrest the driver for DUI. In Washington DC and around the country, this is not an unusual experience.
Symptoms of concussions and alcohol intoxication materialize in very similar ways. Confusion, unusual behavior, and difficulty thinking clearly may be red flags for officers to investigate if a driver is intoxicated.
Officers will have you undergo SFSTs, which test for symptoms of intoxication, but these symptoms are also often experienced by those suffering from a concussion or other head trauma.
Field Sobriety Testing
There are three field sobriety tests officers are instructed to do: Horizontal Gaze Nystagmus, Walk and Turn, and the One Leg Stand.
Horizontal Gaze Nystagmus
In the Horizontal Gaze Nystagmus test, an officer will hold a pen or flashlight in front of your eyes and instruct you to track the object while they move it back and forth. While you do this, the officer is looking for involuntary movements of your eyes (referred to medically as nystagmus), difficulty tracking the object, and dilated, red, or watery eyes.
A person who has a concussion will exhibit many of these signs as well.
Walk and Turn Test
In the walk-and-turn test, officers instruct you to walk a certain number of steps, heel to toe, turn around, and walk back the same number of steps. They are testing your balance, concentration, memory, and ability to follow instructions.
The effects of a concussion might inhibit your ability to complete this test, as balance and memory issues are common concussion side effects.
One-Leg Stand Test
The One Leg Stand test evaluates your ability to stand on one leg without using your arms for balance for a certain time.
As with the Walk and Turn Test, people who have recently suffered concussions often exhibit balance issues, which might lead them to fail the test.
Previous Court Precedent

Standardized field sobriety tests are what officers use to gauge whether someone should be arrested for a Washington DC DUI, and it is obvious a person with a concussion has an extreme likelihood of failing.
While this issue has yet to be litigated in the Supreme Court, it has been in several high state courts. The Supreme Court of Connecticut, in State v. Morelli, overturned a guilty verdict due to the effects of head trauma and standard field sobriety tests.
The court found the lower court had not properly considered the effects of the defendant’s head injuries when he underwent the tests. In the Court’s ruling, they stated, “We agree with … the expert testimony that evidence of a concussion would affect the reliability of the standardized field sobriety tests”.
