The South Carolina Highway Patrol is the highway patrol agency for South Carolina, which has jurisdiction anywhere in the state except for federal or military installations. The Highway Patrol was created in 1930 and is an organization with a rank structure similar to the armed forces. The mission of the South Carolina Highway Patrol includes enforcing the rules and regulations in order to ensure road way safety and reducing crime as outlined by South Carolina law. The Highway Patrol is the largest division of the South Carolina Department of Public Safety and its headquarters is located in Blythewood. This department also includes the South Carolina State Transport Police Division, and the South Carolina Bureau of Protective Services.

The Highway Patrol has many responsibilities. The primary job of the rank and file trooper is traffic law enforcement. This includes traffic collision investigation, issuing warning tickets and citations for traffic violations, and finding, arresting, and processing impaired drivers. A state trooper is a sworn peace officer, and although their primary duty is traffic enforcement, they can perform other law enforcement functions.
