Driving Under Influence Tests
If an officer notices some external signs of driving under influence, like swerving, failure to signal, and erratic changes in speed they can stop the vehicle. They can question the driver and find out the cause for his impaired driving.
Officers can set up sobriety checkpoints where they can stop each vehicle and interview the driver to check if they are driving under influence.
They can also use the following tests.
The Blood Alcohol Content Test
This is the most common way of determining whether a person is driving under the influence of alcohol or not. The Blood Alcohol Test shows the amount of alcohol content in the driver’s blood. It shows how much alcohol the person has consumed but it does not indicate the extent to which the driver is impaired. A driver with BAC greater than .08 is presumed to be driving under influence.
Field Sobriety Tests
There is no BAC test to check the influence of drugs. So field sobriety tests are used for this purpose. They are a set of tests to assess the driver’s level of impairment.
The Horizontal Gaze Test – The driver is asked to follow an object, for example, a pen which is held near his face with his eyes. This is useful to assess the person’s reaction to an object and his eye movement.
The One-Leg Stand Test – In this test the driver is asked to stand on one leg. This helps to assess the person’s balance and synchronization.
The Walk and Turn Test – This test is used to gauge the person’s capacity to follow directions, perform physical and mental tasks simultaneously and to remember a set of steps. The goal of the test is to evaluate the driver’s level of coordination and mental alertness.
Other Tests
The Alphabet Test – The motorist has to recite all the alphabets or a part of them.
The Finger Count Test – In this the driver has to count his fingers.
The Finger to Nose Test – The driver is asked to tilt his head backwards, close his eyes and touch his nose with the index finger of his right and left hand one after the other.
