The California knowledge test is built entirely from the DMV's driver handbook. It is multiple choice, each question has one right answer, and the DMV's permit page sets the passing score at 80%. Signs, signals, lane lines and curb colors make up some of the most learnable material on it, because they follow patterns: a sign's shape and color say what kind of message it carries before you read a single word.

Below are those patterns in tables you can quiz yourself with, the test facts the DMV publishes, what to bring to the appointment, and a week-long study plan for the days after driver education is finished.

The test in numbers

The DMV publishes a pass mark, not a fixed number of questions. On its learner's permit page, the test is described as multiple choice, drawn from the handbook, with 80% required. FFDL 19, the DMV's fact sheet for teens, puts the same idea the other way round: a teen may miss no more than 8 questions.

Tries: three attempts, then a new application.
After a fail: seven full days for a minor before the next try, with the test day itself left out of the count.
Nothing in hand: no handbook, no phone, no other testing aid.
Start early: the permit page says knowledge tests are not given at DMV offices after 4:30 p.m.
No tricks: the DMV's test-preparation page says one answer will be correct and the other two will be clearly wrong or will not fit the question.

If you miss a question, the DMV says office staff can point you to the handbook page that has the answer. Write those page numbers down if you need a second attempt.

Signs: learn the shape first

The handbook's first sign rule saves a lot of memorizing: obey every warning sign, whatever its shape or color. After that, these shapes and colors carry the most points:

Shape or color	Message	Your move
Red eight-sided STOP	Stop completely	Stop at the limit line; with no line, before the crosswalk; with neither, before the intersection. Check every direction
Red downward triangle, YIELD	Someone else may have priority	Slow down, ready to stop for any vehicle, rider or walker
Red and white rectangle, such as DO NOT ENTER	An order	Follow it as written
WRONG WAY	You are facing oncoming traffic	Back out or turn around when it is safe. At night, red reflectors in your headlights are the same warning
Red circle with a slash	The pictured action is banned	Do not do it
Round yellow sign with black markings, or a white X	Railroad crossing ahead	Look and listen, slow down, be ready to stop, and let trains pass
Five-sided sign	School nearby	Drive slowly; stop for children in the crosswalk
Diamond	A road condition or hazard ahead	Slow down and find the hazard
White rectangle	A rule	Obey it

One more rule answers several questions at once. When a traffic light is dark or not working, treat the intersection as if it had STOP signs facing every direction, then go carefully when it is safe.

Signals: solid, flashing and arrows

Most signal questions test the difference between a steady light, a flashing light and an arrow of the same color.

Signal	What it means
Steady green	Go, but only after anyone already in the intersection has cleared it, and only if you can get all the way across before red
Green arrow	A protected turn in the arrow direction; oncoming traffic is held at red
Steady yellow	Caution, red is next. Stop if that can be done safely
Yellow arrow	Your protected turn time is running out
Flashing yellow	Slow down and stay alert; stopping is not required
Flashing yellow arrow	The left turn is allowed, but unprotected: oncoming traffic goes first
Steady red	Stop. After the stop, a right turn is allowed when no sign forbids turning on red
Red arrow	Stop, and stay stopped for that turn until a green light or green arrow
Flashing red	Treat it like a stop sign: stop, then go when it is safe
Flashing Don't Walk	Walkers should not start across, but drivers still yield to anyone already crossing

Lane lines: yellow, white, solid, broken

A short way to remember it: yellow lines divide traffic going opposite ways, white lines divide lanes going the same way, and a broken line is one you may cross when it is safe. Test questions go one level deeper:

Dashed white lines mark lanes heading the same direction; you may move across when it is safe.
A single solid white line also marks same-direction lanes, one-way streets included.
Double solid white lines are a barrier between lanes, often beside a carpool lane or near freeway ramps. Do not change lanes over them.
A single solid yellow line is the middle of a two-way road. If it is on your side and you have just one lane, no passing.
A dashed yellow line on your side allows passing, when it is safe.
Double solid yellow lines forbid passing in both directions. One set may be crossed to turn left into or out of a driveway or private road, or for a lawful U-turn.
Two pairs of double yellow lines with two feet or more between them count as a barrier: no driving on or over it, and no left turn or U-turn across it except at a marked gap.
A center lane with a solid outer edge and a dashed inner edge serves left turns and U-turns only, for 200 feet at most.
White triangles pointing toward you form a yield line, the place to yield or stop.

Two of these show up on the drive test as well: the DMV fails a driver who ignores lane markings or painted arrows.

Curb colors and parking distances

Red: no stopping, standing or parking at all, except buses at a red zone marked for them.
Yellow: loading zone for passengers or freight, for no longer than the posted time; in a noncommercial vehicle you usually have to stay with it.
White: a brief stop to let passengers in or out, nothing longer.
Green: short-term parking, with the time limit on a nearby sign or painted on the curb itself.
Blue: reserved for a disabled driver or passenger, and only with the special placard or license plate.

Distances worth memorizing: no parking within 15 feet of a fire hydrant or a fire station driveway, within 20 feet of a marked or unmarked crosswalk (15 feet where the curb is extended), or in front of or on a curb ramp that gives wheelchair access to a sidewalk. Curb markings count on the drive test too: ignoring them is on the DMV's list of Critical Driving Errors.

What to bring to the permit appointment

Applicants under 18 must be at least 15½. Gather the driver education completion certificate (or a certificate of enrollment in an integrated education and training program), the application with a parent or guardian's signature, documents proving identity and California residency, and money for the fee. At the counter come the vision exam, the photo and then the knowledge test. Two practical points from the DMV's roadmap for teens: the student and the approving parent each set up a separate MyDMV account online, and a parent or guardian must attend the visit.

For families here, the nearest office is the Folsom DMV field office on East Bidwell Street. Pick a morning appointment so the test is well clear of the 4:30 p.m. cutoff. For the paperwork in order, read about the DL 400C certificate and the full permit-to-license timeline.

Online driver education first

Teens under 17½ need driver education before the permit. Stallion Drivers Ed Academy, at stalliondriversed.com, sells a DMV-approved 30-hour online course (California course license E0159). It runs on a phone or a computer at the student's pace, and the DL 400C certificate is mailed when the course is finished. Details are on our online driver education page.

A seven-day study plan

For the week before the appointment, once driver education is done. The DMV's own advice is to allow a few days to work through the handbook.

Day 1, signs and signals: the traffic control part of Section 7. Cover the right column of the two tables above and answer out loud.
Day 2, lanes and turns: Section 6. Draw a two-way street and a four-lane road and label each line.
Day 3, right-of-way and parking: the rest of Section 7, plus curb colors and parking distances.
Day 4, safe driving: Section 8, including following distance, speed and weather.
Day 5, sample tests: work through the DMV's sample Class C knowledge tests. For each miss, find the paragraph in the handbook and read all of it.
Day 6, weak spots: reread the misses and take another sample test.
Day 7, rest: skim the tables, put the documents in one folder, and get a full night's sleep. At the office, read every question to the end before choosing.

From paper to the road

A sign you can name at a desk still has to be noticed from a moving car. During lessons, students call out signs, lines and curb colors as they come into view, so facts from the test become things they act on; the method is on how we teach. For a teen on the usual permit path, family practice cannot start until behind-the-wheel training begins and an instructor validates the permit, which is why booking teen driving lessons soon after the permit matters. The original permit comes to every lesson.

Quick answers

How many questions can you miss on the California permit test? The pass mark is 80%. In the DMV's words for teens, up to 8 wrong answers still pass.

How many tries do you get? Three before a new application is needed. After a failed attempt, a minor waits a full seven days; the test day itself is not counted.

What is the best way to study? The DMV handbook itself, plus the DMV's sample Class C tests. Every question on the real test comes from the handbook.

Which sign has five sides? The school sign. Drive slowly near it, and stop for children in the crosswalk.

What does a flashing yellow arrow mean? The left turn is allowed, but unprotected, so oncoming traffic goes first.
