South Dakota CDL Practice Test — General Knowledge, Air Brakes & Endorsements (2026)
South Dakota's commercial driver license (CDL) program requires passing multiple written knowledge tests covering general CDL knowledge and air brakes. Applicants must be at least 18 years old for intrastate operation or 21 for interstate. The first step is obtaining a commercial learner's permit by passing knowledge tests and a vision exam. CDL endorsements are available for doubles/triples, tanker vehicles, passenger transport, and hazardous materials. Note that a CDL does not permit motorcycle operation unless combined with a Class 3 license (e.g., A3 for Class A vehicles plus personal vehicle operation including motorcycles).
