Traveling across state lines from California into Nevada or Arizona carries significant risk due to conflicting drug and traffic safety laws.
1. The Cannabis Transport Trap
While recreational cannabis is legal in California, Nevada, and Arizona, transporting cannabis **across state lines is a federal offense** (interstate drug transportation). Additionally, possessing cannabis on federal lands (such as the Mojave National Preserve bordering California) is fully illegal and prosecuted in federal court.
2. Extreme DUI Laws in Arizona
Arizona has some of the strictest DUI laws in the United States. Driving with a BAC of **0.08% or higher** triggers mandatory jail time (even for first offenses). Under Arizona's "Extreme DUI" and "Super Extreme DUI" laws, high BAC levels carry mandatory ignition interlock devices and massive fines. California licenses can be suspended in California due to Arizona convictions via the Interstate Compact.
3. Out-of-State Driver Licensing Compact
California, Arizona, and Nevada participate in the **Driver License Compact**. If you receive a traffic violation, reckless driving charge, or DUI arrest in Nevada or Arizona, details are shared with the California DMV, which will suspend your CA driver's license accordingly.
