California DMV Permit Practice Test

Lane splitting — a motorcycle riding between lanes of traffic — was tolerated but not explicitly legal in California for decades. The California Highway Patrol issued informal safety guidelines but there was no statute. In 2016, California enacted AB 51, codified as CVC § 21658.1, to formally define and legalize lane splitting at safe speeds (no more than 10 mph over traffic, not exceeding 30 mph). No other U.S. state has followed with a comparable explicit statute, though some states tolerate it without prohibition. The law is tested on California's knowledge exam because all drivers must understand that motorcycles may legally occupy the space between lanes.

California's APS law (CVC § 13353.2) allows the California DMV to suspend a driver's license based solely on a DUI arrest and chemical test result — without waiting for a criminal conviction. A BAC of 0.08%+ at arrest triggers an automatic 4-month suspension. The driver has exactly 10 days from the arrest date to request a DMV hearing to contest the suspension. If the 10-day window is missed, the suspension proceeds automatically at 30 days post-arrest. The APS suspension and the criminal DUI prosecution proceed on separate tracks simultaneously.

CVC § 12814.6, California's provisional license statute, specifically restricts passengers under 20 years of age (not under 21) during the first 12 months. The California Legislature's research found that crash risk associated with teen peer passengers drops significantly once passengers are 20 or older. This California-specific '20' threshold is a frequent trap on the knowledge exam because test-takers who remember 'under 21' from other contexts will get the answer wrong.

The center two-way left turn lane (CVC § 21460.5) — informally called the 'suicide lane' — is the center lane marked with yellow lines that allows vehicles from both directions to make left turns. In California, this lane may ONLY be used to begin a left turn from the road or to complete a left turn from the opposite direction. It may NOT be used as a travel lane for moving traffic, for passing, or for merging into traffic from a driveway or side street. Using the center lane as a travel lane is a violation under CVC § 21460.5.

Applicants 18 and older take a 36-question test; applicants under 18 take a 46-question test. Both require 80% to pass (approximately 29/36 or 37/46 correct). California allows up to three attempts per application. If all three fail, the application expires — you must start over, pay a new $38 application fee, and submit a new DL 44 form. A new application also resets the three-attempt counter.

The California Driver Handbook emphasizes a minimum 3-second following distance at any speed in normal conditions. To measure: pick a fixed object ahead; count the seconds between when the vehicle ahead passes it and when you reach it — it should be 3 or more seconds. In rain, fog, or heavy traffic, California's handbook recommends extending to 4 or more seconds. California specifically tests the 3-second rule (not a specific car-length count, which varies by speed) because it scales correctly across different speeds.

California DUI BAC thresholds: (1) Adults 21+ — 0.08%; (2) Commercial drivers — 0.04%; (3) Drivers under 21 — 0.01% (effectively zero tolerance). The 0.01% under-21 threshold is stricter than most states' 0.02% standard. California's APS law also triggers an automatic license suspension at arrest for 0.08%+ BAC (adults) or 0.01%+ BAC (under 21), independent of criminal charges.

Yes — California offers the knowledge test in 36 languages, more than any other U.S. state. Languages include Spanish, Mandarin, Cantonese, Vietnamese, Tagalog, Korean, Armenian, Japanese, Punjabi, Hindi, and dozens more. Request your language when scheduling your DMV appointment at dmv.ca.gov. Traffic signs on the test are shown visually as they appear on actual roads — not translated — regardless of the language chosen for the written portions.

California's prima facie speed limit of 15 mph applies in specific locations: (1) in any alley, (2) when approaching a railroad crossing where view is obstructed, and (3) near schools, playgrounds, and senior centers when children or seniors are present. The 15 mph limit applies even if no sign is posted in these locations. The standard California residential prima facie limit is 25 mph. Near schools and senior centers during operating hours, the 15 mph limit is posted and enforced with doubled fines.

You need a completed DL 44 application form (available at DMV offices or online), proof of California residency (two documents such as utility bills or bank statements), your Social Security number or ITIN, and the $38 application fee as of 2025. If under 18, a parent or legal guardian must sign the DL 44. You will also take a vision test at the DMV at no additional cost. Scheduling online at dmv.ca.gov is strongly recommended to avoid long wait times.
