A designated driver is a person who agrees to remain sober and abstain from alcohol consumption during social events, particularly when others are drinking. This individual is responsible for safely transporting friends or family members home, ensuring everyone arrives without the risk of driving under the influence. The concept of a designated driver promotes safety and responsibility, reducing the likelihood of accidents caused by impaired driving. Many social gatherings, such as parties or celebrations, encourage the use of a designated driver to protect both the driver and other road users, contributing to a safer community overall.
