Driver Licensing Policy and Issuance (Issuance of Driver's License; Driver Manuals; Medical and Vision Requirements)
Issuance chain
DMV issues a driver license only after application, identity and residency verification, a vision screening, the knowledge test, and the behind-the-wheel test. Minors receive a provisional license with restrictions for the first 12 months: no passengers under 20 unless a licensed driver age 25 or older is present, and no driving between 11 p.m. and 5 a.m. unless necessary. Adults receive a standard license; a REAL ID requires additional identity and residency documents.
Driver manuals
DMV publishes the current California Driver Handbook and supplements for motorcycle, commercial, and parent-teen audiences. Schools should teach from the current official edition. Using an outdated or altered manual can mislead students about current laws and test content.
Medical and vision requirements
DMV screens vision, generally requiring about 20/40 acuity with the best correction, and checks visual field. A failure leads to referral; DMV may issue a restricted license or deny issuance. Medical conditions such as epilepsy, diabetes, heart disease, dementia, or sleep disorders may require a Driver Medical Evaluation (DL 51). Lapses of consciousness are reportable, and DMV may suspend driving until the condition is controlled. Restrictions can limit driving time, area, or vehicle equipment.
Worked example
A 17-year-old passes the driving test and receives a provisional license. That night the licensee wants to drive two 18-year-old friends at 10:30 p.m. This is not allowed: during the first 12 months, the passenger and nighttime restrictions apply. A medical restriction would add further limits.
Traps
Assuming provisional restrictions end exactly at age 18; ignoring a vision referral; using an old driver manual; treating a DL 51 as optional; forgetting that restrictions may require specific equipment.
