Impairment and distraction reduce the abilities driving depends on: perception, judgment, reaction, coordination, and attention. Responsible driving also includes restraints and knowing what to do after a collision.
Visual guide for this module
Study the shape, color, signal, or marking and name the safe response before reading the explanation.
Impairment is broader than alcohol
Alcohol, cannabis, illegal drugs, prescription medicines, and some over-the-counter medicines can impair driving. Read medication warnings and do not drive when a substance makes safe operation uncertain.
Distraction steals observation time
A driver looking at or interacting with a device may miss changing traffic, a pedestrian, a signal, or a developing hazard. Follow California's current device-use rules and keep attention on driving.
Restraints reduce injury risk
Seat belts and correctly used child restraints are basic occupant-protection systems. Review current California age, size, and seating requirements in authoritative state guidance.
After a collision
Stop as required, address immediate safety and injury concerns, exchange or report information as required, and follow California's current collision-reporting obligations. Requirements can change, so verify thresholds and procedures with the DMV.
