Common Tests in Missouri

There are multiple tests an arresting officer may administer when they pull a person over.

If you are suspected of DWI, you may be subject to any of the following:

  • Horizontal Gaze Nystagmus
  • Walk and Turn
  • One Leg Stand
  • Finger to Nose

When performing the sobriety tests, it can be easy for officers to skip a specific step integral to each test. With the Guilfoil Law Group on your side you can be sure that these steps will never go overlooked. Our Kansas City DWI lawyer provides solid defense when it comes to testing.
