Which methods are commonly used to assess driver impairment during a DUI stop?

The correct answer includes field sobriety tests, breathalyzer tests, and medical evaluations as the primary methods used to assess driver impairment during a DUI stop.

Field sobriety tests are standardized physical exercises designed to provide law enforcement with indicators of impairment. These tests evaluate balance, coordination, and the ability to follow instructions, which can be impacted by alcohol or drug use.

Breathalyzer tests measure the blood alcohol concentration (BAC) in a person's breath, providing a quantitative metric that supports the observation made during the field sobriety tests. This result helps law enforcement determine the level of impairment accurately.

Medical evaluations may also be conducted if a driver's impairment is suspected to be due to a medical condition or drug use rather than alcohol. This involves assessing the driver’s physical state and can be crucial in understanding their ability to operate a vehicle safely.

In contrast, the other options focus on methods that are not standard practice for assessing immediate driver impairment during a stop. Driving simulations and theoretical quizzes do not provide real-time evidence of an individual’s current state and are typically not utilized by law enforcement on the street. Public opinion surveys and social media analysis might give insights into broader trends in DUI behavior but are not practical tools for immediate assessment at a traffic stop. Background
