South Carolina and other states have a variety of strategies that they can use to curb drunk driving. For instance, the law states that drivers cannot operate a motor vehicle with a blood alcohol content (BAC) of .08% or higher. If a driver is under 21, he or she cannot operate a motor vehicle with a BAC of .02% or higher. The use of ignition interlock devices can make it harder for an individual to start a car after consuming alcohol.

If a person registers a .02% BAC or higher after blowing into the device, the vehicle is unlikely to start. Sobriety checkpoints could also be used to reduce the number of drunk drivers on the road. Typically, checkpoints are conducted in areas that are known to have a high number of impaired drivers. They may also be used during holidays or other times when drunk driving may be more likely to occur.

Individuals who are suspected of being impaired may be subject to breath or other types of testing. Drivers who refuse to cooperate could be at risk for losing their license. This may be the case whether or not a person is found guilty of drunk or impaired driving. Authorities may reduce the number of drunk drivers through mass media or other educational campaigns.

A person who is charged with DUI could face a variety of negative consequences if a conviction is obtained. They could include jail or prison time, a fine or a drivers license suspension. It may also be possible for an individual convicted of DUI to spend time on probation or be ordered to perform community service. An attorney may help a driver avoid these or other potential consequences by casting doubt on evidence or challenging the validity of the traffic stop itself.
