Before a DUI case goes to trial in South Carolina or anywhere else, a pre-trial motion may be considered by a judge. The motion may ask that certain evidence be suppressed or cover any other concerns that an attorney may have. In some cases, a request will be made to drop the matter altogether. The prosecution in a DUI case can also make motions before a trial to limit the type of evidence that can be introduced at trial.
People in South Carolina may wonder when police have the right to pull people over if they suspect someone is driving while under the influence. In general, police can only stop drivers if they have some kind of reasonable suspicion of a crime. There are exceptions to this rule; while controversial, sobriety checkpoints have been upheld in most states as an exception to the rule so long as all drivers passing by a specific area are checked for drunk driving.
