What is the standard procedure for a DUI traffic stop?

The correct response encompasses all the critical steps involved in a DUI traffic stop.

Initially, conducting an initial observation is vital. This involves assessing the driver for any signs of impairment, such as erratic driving behaviors, physical indicators of intoxication, or any other observable actions that may signal a potential DUI.

Following this, if there are enough grounds based on the initial observation, the officer will typically request the driver to perform field sobriety tests. These tests are structured to measure the driver's coordination, balance, and cognitive functions, which can provide further evidence of impairment.

Finally, after evaluating the results of both the initial observations and the field sobriety tests, the officer will determine if an arrest is justified. This decision is based on the culmination of evidence gathered during the traffic stop, ensuring that any action taken aligns with legal protocols and standards for DUI enforcement.

By including the entire procedure, the response illustrates the systematic and comprehensive approach required when handling suspected DUI offenses, thus reinforcing the importance of thoroughness in law enforcement practices.
