Colorado POST Practice Exam

What action should be taken if a police officer suspects drug use during a traffic stop?

1. Let the driver go if they seem cooperative

2. Conduct a field sobriety test and check for signs of intoxication

3. Request the driver to call a friend

4. Perform a full vehicle search immediately

The correct answer is: Conduct a field sobriety test and check for signs of intoxication

Conducting a field sobriety test and checking for signs of intoxication is appropriate because it allows the officer to assess the driver's physical and cognitive abilities, which may be impaired due to drug use. Field sobriety tests are standardized procedures that provide law enforcement with observable indicators of impairment. These tests help gather evidence that can support further actions, such as arrest or additional testing. In situations where officers suspect drug use, it is essential to use standardized testing methods, such as field sobriety tests, to ensure that any conclusions drawn are based on observable behavior and are in line with legal standards. This approach also maintains the integrity of the investigation and any subsequent legal proceedings. Other actions, such as letting the driver go based on their demeanor or simply requesting that they call a friend, would not address the potential issue of impaired driving. While immediate vehicle searches may sometimes be justified, they require probable cause, and by conducting field sobriety tests first, the officer gathers necessary evidence to support any further actions.
