These guidelines are issued by the National Highway Traffic Safety Administration (NHTSA).
According to defense attorneys in Houston, the tests include:
There are a number of ways an experienced DWI lawyer can counter field sobriety test results in court.
He or she can challenge the accuracy of the test itself, or question the way the tests were administered by the police officer.
There are also instances when a driver’s physical condition may affect the results of a field sobriety test even if the officer thinks he had conducted them properly.
For example, someone with an inner ear infection may temporarily have an impaired sense of balance.
It would be very easy for this person to fail the OLS portion of the test (which tests for balance) and be judged to be intoxicated.
Someone with a neurological impairment can easily fail the HGN test, while a person with a muscular disorder may not be able to walk heel to toe on a straight line and thus fail the WAT portion of the test.
Another factor affecting the WAT test is an uneven or gravel road surface or that the person took the test in high heels making balancing difficult.
