Dec 11, 2025

Overview

  • Practice DMV written test: 49 multiple-choice questions with correct answers explained.
  • Focus: California driving laws, safety rules, parking, passing, signals, and collisions.
  • Useful for preparing for the DMV written exam.

Key Rules and Speed Limits

  • Railroad crossing with no warnings and limited visibility: max 15 mph.
  • Residential area speed limit (unless posted): 25 mph.
  • Freeway posted speed must be obeyed; do not exceed posted limit (example: posted 65 mph).
  • Basic speed law: never drive faster than is safe for current conditions.

Passing, Lane Use, and Merging

  • Do not drive off paved roadway to pass another vehicle under any circumstances.
  • Merging onto freeway: drive at or near the same speed as freeway traffic.
  • Passing: only cross double yellow lines to pass if your side is a broken line.
  • When planning to pass, do not assume other driver will make space to return to lane.
  • On a one-way street, left turn onto another one-way allowed if traffic on the street moves to the left.

Signals, Turns, and Following Distance

  • Signal continuously at least 100 ft before turning.
  • To avoid last-minute moves, look 10–15 seconds ahead.
  • When making a right turn, slow down or stop if necessary before turning.
  • Defensive driving: keep your eyes moving to detect hazards.
  • Do not tailgate; it increases accident risk and frustrates other drivers.

Parking Rules

  • Parallel parking: wheels must be within 18 inches of the curb.
  • Parking uphill on two-way street with no curb: turn front wheels to the right (away from the street).
  • White painted curb: loading zone for passengers or mail only.
  • Do not park next to a red-painted curb.
  • Illegal to park in an unmarked crosswalk.
  • May not park within 100 ft of an elementary school (question phrasing flagged red curb as correct illegal parking).

Intersections and Blocking

  • Never legally block an intersection under any circumstances.
  • If traffic blocks an intersection when you have a green light, stay out until it clears.
  • If in the middle of an intersection when hearing an emergency siren, continue through then move right and stop.

Railroad Crossings and Vehicle Types

  • Always stop before crossing tracks if you cannot fully clear the other side.
  • Vehicles that must always stop before crossing railroad tracks: tank trucks with hazardous materials placards.
  • Stop at tracks when you lack room on the other side to completely clear them.

School Buses, Crossing Guards, and Pedestrians

  • Stop for a stopped school bus with red lights flashing and remain stopped while lights flash.
  • Obey school crossing guards at all times.
  • If a pedestrian is crossing (no crosswalk), stop and let them finish crossing.

Visibility, Weather, and Lights

  • In fog, use low beams.
  • In dust storms reducing visibility, drive slower and turn on headlights.
  • First rain after dry spell makes roadways most slippery.

Large Vehicles and Blind Spots

  • Large trucks have larger blind spots than most passenger vehicles.
  • When following a large truck on freeway, leave more distance than for a passenger vehicle.
  • Large trucks may swing wide to complete right turns.

Legal Responsibilities and Reports

  • Notify DMV within 5 days after selling or transferring your vehicle.
  • Submit SR-1 written report to DMV if property damage exceeds $1,000 or if there are any injuries.
  • If you hit a parked vehicle and cannot find owner, leave a note and report to police or CHP.

Bike Lanes and Construction Zones

  • You may drive in a bike lane only when within 200 ft of a cross street where you plan to turn right.
  • Obey signal persons at road construction sites at all times.

Laws and Illegal Practices

  • Illegal: listening to music through headphones that cover both ears while driving.
  • Do not assume other drivers will maintain constant speed or yield just because you signal.
  • Do not drive too slowly so that you block traffic.

Miscellaneous Specifics (Selected Q&A Summary)

  • Turning left from a multi-lane one-way onto a one-way: start from lane closest to left curb.
  • Double solid yellow lines two or more feet apart: may not be crossed for any reason.
  • Flashing yellow traffic signal: slow down and cross carefully.
  • When turning right, signal 100 ft before turning.
  • Safest phone practice: use hands-free devices to keep both hands on wheel.

Key Terms and Definitions

  • Basic Speed Law: drive no faster than is safe for current conditions regardless of posted limit.
  • SR-1: DMV traffic accident report required for certain damage or injuries.
  • Double Solid Yellow Lines: division you may not cross for any reason.
  • Blind Spot: area not visible in mirrors; larger for trucks.

Action Items / Next Steps

  • Review parking distance rules (18 in from curb; curb-side rules uphill/downhill).
  • Memorize required notification/reporting timelines (DMV 5 days; SR-1 thresholds).
  • Practice scanning 10–15 seconds ahead and signaling 100 ft before turns.
  • Study laws regarding school buses, railroad crossings, and double yellow lines.
