Slowed reaction time and impaired judgment

Alcohol slows reaction time, impairs judgment, and reduces coordination, all of which are essential for safe driving.

The Department of Licensing can suspend their license even before any court conviction

Washington imposes an administrative license suspension through the Department of Licensing that is separate from any criminal court penalty.

Question 5

A designated driver at a party has one strong mixed drink an hour before leaving. Which statement is most accurate?
