The One-Leg Stand Test is another commonly used field sobriety test that law enforcement officers employ to assess a driver's balance, coordination, and divided attention. The purpose of this test is to determine if a driver is impaired by alcohol or drugs while operating a vehicle.


During the One-Leg Stand Test, the officer typically instructs the driver to perform the following steps:


  1. Instruction Stage: The officer provides verbal instructions, explaining and demonstrating how the test should be performed. The driver is usually asked to stand with their feet together, arms at their sides, and listen attentively to the instructions.

  2. Balance and Counting Stage: The driver is instructed to raise one leg approximately six inches off the ground while keeping their raised foot parallel to the ground. They are then instructed to count out loud, usually starting from one thousand and counting by thousands (e.g., one thousand-one, one thousand-two, etc.) until instructed to stop.

  3. Observation Stage: While the driver is performing the test, the officer closely observes for various indicators of impairment, including:

    • Swaying or inability to maintain balance while standing on one leg.
    • Use of arms for balance, such as raising them to the side or flailing.
    • Hopping or putting the foot down to regain balance.
    • Inability to follow instructions accurately or losing track of the count


It's important to note that the One-Leg Stand Test, like other field sobriety tests, is subjective and can be influenced by factors such as physical conditions, fatigue, nervousness, or pre-existing medical conditions. These factors can potentially affect a driver's ability to perform the test regardless of their level of impairment.


If the officer observes signs of impairment during the One-Leg Stand Test, it may provide them with probable cause to proceed with further testing, such as a breathalyzer test or blood test, to gather additional evidence of intoxication.


If you find yourself in a situation where you have undergone a One-Leg Stand Test or any other field sobriety test and are facing legal consequences, it is advisable to consult with a DUI/DWI attorney who can provide you with appropriate legal advice based on the specific laws and regulations in your jurisdiction. They can guide you through the legal process and help protect your rights.
