When the police in New Jersey suspect you of drunk driving, they perform several sobriety tests to determine whethe there is probable cause to arrest you. One of them is the One Leg Stand (OLS) Test. This test is common in DUI stops, but can be failed for a number of reasons other than intoxication.

In this test, you are instructed to stand with one foot approximately six inches off the ground and count aloud by thousands (i.e. One thousand-one, one thousand-two, etc.) until told to put your foot down. The officer times you for 30 seconds. During this time he looks for four indicators of impairment, including

  • swaying while balancing
  • using arms to balance
  • hopping to maintain balance, and
  • putting your foot down.

How Do I Know If I Failed?

Research done by the National Highway Traffic Safety Administration (NHTSA) indicates that 83 percent of individuals who exhibit two or more such indicators in the performance of the test will have a BAC of 0.08% or greater.

However, other conditions can cause a bad result with this test, such as a knee or hip injury, dizziness, or other problems with balance or coordination. An officer should ask you if you have any conditions that could interfere with the test.
