1-1. Signs, Signals, and Pavement Markings
★★★★★ 20% (estimate)
Overview
This chapter is about reading the road. Traffic lights, signs, and painted lines all give you orders or warnings, and the test checks whether you know what each one means. Most of the rules come down to a few simple patterns: the color, the shape, and whether a light is steady or flashing.
Lights come first. A steady red means stop and wait, but a flashing red works just like a stop sign: stop fully, then go when it is safe. A flashing yellow does not make you stop; it tells you to slow down and watch out. If the signal is dark or broken, every driver treats the intersection as an all-way stop.
Signs speak through shape. An eight-sided sign always means stop, an upside-down triangle means yield, a five-sided sign marks a school zone, and a diamond warns of a hazard ahead. A round yellow sign tells you a railroad crossing is coming.
Lines on the road tell you about traffic direction. Yellow lines separate traffic going opposite ways, and white lines separate lanes going the same way. A double solid yellow line means no passing, while a broken yellow line on your side means you may pass when it is safe.
Key notes
- Flashing red light
- — Treat it exactly like a stop sign. Come to a full stop, yield to anyone who has the right of way, and go only when it is safe.
- Flashing yellow light
- — A warning. You do not have to stop, but you must slow down and pay extra attention before going through.
- Traffic signal not working
- — When a traffic light is dark or out of order, every driver must stop as if the intersection had a stop sign on every corner, then take turns.
- Sign shapes
- — Octagon (8 sides) = stop. Upside-down triangle = yield. Pentagon (5 sides) = school zone or school crossing. Diamond = warning of a hazard. Round = railroad crossing ahead.
- Yellow vs. white lines
- — Yellow lines divide traffic moving in opposite directions. White lines divide lanes moving in the same direction and also mark the right edge of the road.
- Double solid yellow line
- — No passing in either direction. You may cross it only to turn left into or out of a driveway or private road, or to make a legal U-turn.
★ Exam points
- Test writers like to swap flashing red and flashing yellow. Only flashing red requires a full stop.
- A broken signal is an all-way stop, not a yield and not 'whoever is fastest.'
- Know the shapes: the pentagon (school) and the round sign (railroad ahead) are the ones people mix up.
- Passing is allowed only where the broken line is on your side of the road.
1-2. Right of Way and Turns
★★★★★ 20% (estimate)
Overview
Right-of-way rules decide who goes first when two road users want the same space. The law never gives anyone the right to cause a crash, so the main idea is to yield whenever going ahead could put someone in danger. This chapter covers four-way stops, uncontrolled intersections, left turns, roundabouts, and pedestrians.
At a four-way stop, the first driver to come to a full stop goes first. If two drivers stop at the same time, the one on the left yields to the one on the right. A driver turning left must wait for oncoming traffic that is close enough to be a danger.
Roundabouts move counterclockwise, so you always enter to the right. Drivers already in the circle have the right of way, and entering drivers wait for a gap.
Pedestrians in any crosswalk, marked with paint or unmarked at a corner, get the right of way. A person using a white cane or a guide dog must always be given the right of way. When you turn, you must also signal for the last 100 feet before the turn.
Key notes
- Four-way stop
- — The first vehicle to stop completely gets to go first. If two vehicles stop at the same moment, the driver on the left lets the driver on the right go first.
- Left turn
- — A driver turning left must yield to oncoming vehicles that are close enough to be a danger, and to pedestrians crossing the street they are turning into.
- Roundabout
- — A circular intersection where all traffic moves counterclockwise. Drivers entering the circle yield to vehicles already inside it.
- Pedestrians in a crosswalk
- — Drivers must yield to people walking in a crosswalk. Most corners have a crosswalk even when no lines are painted (an unmarked crosswalk).
- Blind pedestrian
- — A person walking with a white cane or a guide dog always has the right of way. Do not honk at them, since the sound can confuse them.
- Turn signal distance
- — Signal for at least the last 100 feet before you turn, so other drivers know what you plan to do.
★ Exam points
- The tie rule at a four-way stop is 'yield to the right,' not 'yield to the left.'
- Questions often ask about an unmarked crosswalk. Pedestrians there still have the right of way.
- In a roundabout, the car already in the circle goes first, not the car entering.
- Expect the number 100 feet for turn signals.
1-3. Speed, Lanes, and Parking
★★★★★ 20% (estimate)
Overview
This chapter covers how fast you may drive, how to use lanes, and where and how to park. Many test questions here are about specific numbers, so it helps to learn them as a small set. Above all of them sits the Basic Speed Law: you must never drive faster than is safe for the conditions, even if you are under the posted limit.
California has several special speed limits. In alleys and at blind intersections or blind railroad crossings, the limit is 15 mph. Near a school with children present, the limit is usually 25 mph. On most highways the top limit is 65 mph.
When you park parallel to a curb, your wheels must be within 18 inches of it. On a hill, turn your wheels so the car would roll into the curb, not into traffic. Curb colors also give orders: red means no stopping, white is for picking up or dropping off passengers, green is for limited-time parking, and blue is for people with a disabled placard or plate only.
Key notes
- Basic Speed Law
- — You may never drive faster than is safe for current conditions such as rain, fog, traffic, or road surface, no matter what the posted speed limit is.
- 15 mph zones
- — The speed limit is 15 mph in any alley, at a blind intersection, and at a blind railroad crossing, where you cannot see far enough in each direction.
- School zone speed
- — Unless signs say otherwise, the limit near a school is 25 mph when children are present.
- Maximum highway speed
- — On most California highways the maximum speed limit is 65 mph, unless signs post a different limit.
- Parallel parking distance
- — When parking parallel to a curb, your wheels must be within 18 inches of the curb.
- Parking on a hill
- — Facing downhill, turn the front wheels toward the curb. Facing uphill with a curb, turn the wheels away from the curb. Always set the parking brake.
- Curb colors
- — Red: no stopping, standing, or parking. White: stop only long enough to pick up or drop off passengers or mail. Green: park for a limited time. Blue: disabled parking only, with a placard or plate.
★ Exam points
- Driving under the posted limit can still break the Basic Speed Law if conditions are bad.
- Know the number set: 15 mph (alley, blind spots), 25 mph (school with children), 65 mph (most highways), 18 inches (curb).
- Hill parking questions usually ask which way to turn the wheels. Downhill = toward the curb.
- White and green curbs are the ones people confuse: white is drop-off only, green is short-time parking.
1-4. Safe Driving and Sharing the Road
★★★★☆ 20% (estimate)
Overview
This chapter is about habits that keep you out of crashes. It covers how much space to leave around your car, how to drive at night and in bad weather, and how to share the road with people who are harder to see or slower to stop. The common idea is simple: give yourself time and space to react.
Keep at least three seconds between you and the car ahead, and leave more room in rain, fog, or heavy traffic. If your car starts to skid, ease off the gas and steer in the direction you want the car to go.
Other road users need extra care. When you pass a bicyclist, leave at least 3 feet. Large trucks have big blind spots, so stay out of the areas where the driver cannot see you. When an emergency vehicle comes with its siren and red lights on, pull to the right edge of the road and stop until it passes. When a school bus shows flashing red lights, stop and stay stopped until the lights turn off.
Key notes
- Three-second rule
- — Pick a fixed object ahead. When the car in front passes it, count 'one thousand one' to 'one thousand three.' If you reach the object first, you are too close. Use more time in bad weather.
- Passing a bicyclist
- — When you pass a person riding a bicycle in the same direction, leave at least 3 feet between your car and the bike. If you cannot, slow down and wait until it is safe.
- Emergency vehicles
- — When a police car, fire engine, or ambulance approaches with a siren and red lights, drive to the right edge of the road and stop. Stay stopped until it has passed.
- School bus with flashing red lights
- — When a school bus has its red lights flashing, stop and stay stopped until the red lights stop flashing. Children may be crossing the road.
- Skidding
- — If your car starts to slide, take your foot off the gas, do not slam the brakes, and steer the way you want the front of the car to go.
- Truck blind spots
- — Large trucks have big areas around them, beside, close behind, and right in front, where the driver cannot see you. Do not linger there, and do not cut in close in front of a truck.
★ Exam points
- Following distance questions expect 'three seconds,' not a number of car lengths.
- Emergency vehicle: the answer is 'pull to the right and stop,' not 'speed up to get out of the way.'
- The bicycle passing distance is 3 feet.
- In a skid, braking hard is the wrong answer.
1-5. Alcohol, Phones, and Licensing Laws
★★★★☆ 20% (estimate)
Overview
This chapter covers the laws that the test treats as serious: alcohol and drugs, cell phones, seat belts, and what to do after a collision. These rules carry fines, license suspension, and sometimes jail, so the test asks about the exact limits.
For drivers 21 and older, it is illegal to drive with a blood alcohol concentration (BAC) of 0.08% or higher. For drivers under 21, the limit is 0.01%, which is almost zero. By driving in California, you have agreed in advance to take a breath or blood test if an officer lawfully asks; this is called implied consent.
You may not hold a phone in your hand while driving. Adults may use a phone only in hands-free mode, but drivers under 18 may not use a phone at all, even hands-free. Everyone in the car must wear a seat belt.
If you are in a collision where anyone is hurt or killed, or property damage is over $1,000, you must report it to the DMV within 10 days. This report is required even if the police were called and even if the crash was not your fault.
Key notes
- BAC limits
- — It is illegal to drive with a blood alcohol concentration of 0.08% or more if you are 21 or older, or 0.01% or more if you are under 21.
- Implied consent
- — By driving in California, you have already agreed to a chemical test (breath or blood) if you are lawfully arrested for driving under the influence. Refusing can lead to losing your license.
- Handheld phone ban
- — Drivers may not hold a phone or other wireless device while driving. A phone may be used hands-free, or mounted and touched with a single tap or swipe.
- Drivers under 18 and phones
- — A driver under 18 may not use a cell phone at all while driving, not even in hands-free mode, except to call for help in an emergency.
- Collision report to the DMV
- — Report a collision to the DMV within 10 days if anyone was injured or killed, or if property damage was more than $1,000.
- Seat belts
- — The driver and every passenger must wear a seat belt. Children must ride in the proper child safety seat or booster for their age and size.
★ Exam points
- Watch for 0.08% (21 and older) vs. 0.01% (under 21). Test choices often swap them.
- Hands-free is allowed for adults but not for drivers under 18.
- The DMV collision report is due within 10 days, even if police made a report.
- Implied consent means you already agreed to testing; refusing has its own penalty.
