In vehicle stops for DUI checks, what can officers conduct if necessary?

In the context of vehicle stops for DUI checks, officers are authorized to conduct roadside sobriety tests when necessary. These tests are designed to assess a driver's physical and cognitive abilities, which may indicate whether the driver is under the influence of alcohol or drugs. Roadside sobriety tests typically include tasks such as walking in a straight line, balancing on one leg, and following a moving object with the eyes. The purpose of these tests is to provide law enforcement with evidence regarding a driver's impairment.

While other options may involve elements of vehicle safety or legality, they are not relevant to the specific purpose of assessing a driver's sobriety at a DUI checkpoint. Vehicle repairs, license renewals, and insurance checks are administrative processes and do not directly relate to the immediate assessment of impairment during a roadside stop. Therefore, roadside sobriety tests are the correct action for officers in this context.
