Alcohol, Drugs & Graduated Licensing
Impaired driving is a leading cause of serious crashes, and Kansas sets strict limits, especially for young drivers. The graduated licensing system also builds experience in stages before granting full driving privileges.
BAC limits
A driver 21 or older is guilty of DUI at a BAC of 0.08 or higher. Alcohol slows reaction time and impairs judgment; drugs, including some prescriptions, can impair you too. By having a license you give implied consent to alcohol testing.
Zero tolerance for under 21
Because it is illegal for anyone under 21 to drink, Kansas applies a zero-tolerance limit of 0.02 BAC for underage drivers. A violation can suspend a young driver's license.
Graduated licensing stages
Kansas licensing begins with an instruction permit at 14 (with a licensed adult 21+ supervising), then a restricted license, then full privileges around 16.5 to 17. During the restricted phase, drivers face a 9 p.m. to 5 a.m. night limit (with work, school, and religious exceptions) and may carry no more than one non-sibling minor passenger.
