California's Move Over law requires drivers to change lanes away from a stopped emergency or service vehicle, or slow to a safe and reasonable speed if a lane change is not possible.

Question 5: Under California's administrative per se (APS) law, a driver arrested for DUI with a BAC of 0.08% or higher will have their license automatically suspended by the DMV for a first offense for:

4 months (Correct answer)
6 months
1 year
30 days

Correct answer: 4 months

Under California Vehicle Code 13353.2, a first-offense APS suspension for a BAC at or above 0.08% is four months.

Question 6: What is the primary purpose of measuring skid marks at a collision scene?

To calculate the time of day the collision occurred
To determine the color of the tires
To identify the vehicle manufacturer
To estimate the vehicle's pre-braking speed (Correct answer)

Correct answer: To estimate the vehicle's pre-braking speed

Skid mark length is used with the drag factor in the speed formula to estimate how fast the vehicle was traveling before braking began.

Photos of the involved parties' driver's licenses
Photos of the investigating officer's badge number
Wide-angle overview shots establishing the overall scene (Correct answer)
Close-up photos of vehicle damage

Correct answer: Wide-angle overview shots establishing the overall scene

Overview photographs should be taken first to establish the general scene before any evidence is moved, then progress to mid-range and close-up photos.

Question 9: Which statement about a blood test versus a breath test in California DUI enforcement is accurate?

Breath tests require a warrant in all California cases
Breath tests are more accurate and cannot be challenged
Blood tests measure BAC directly while breath tests use a conversion ratio (Correct answer)
A driver always has the right to choose between blood and breath

Correct answer: Blood tests measure BAC directly while breath tests use a conversion ratio

Breath tests measure deep-lung air alcohol and apply a partition ratio (typically 2100:1) to estimate BAC, while blood tests directly measure alcohol concentration in the blood.

Question 10: A CHP officer stops a vehicle and observes a loaded firearm in plain view on the back seat. The registered owner, who is driving alone, has no criminal record. What should the officer do?

Issue a citation for having an unsecured firearm and release the driver
Confiscate the weapon and release the driver pending investigation
Immediately arrest the driver for illegal possession
Determine if the driver has a valid Carry Concealed Weapon (CCW) permit or qualifies for an open carry exemption (Correct answer)

Correct answer: Determine if the driver has a valid Carry Concealed Weapon (CCW) permit or qualifies for an open carry exemption

The officer must determine whether the driver has a valid CCW or falls under a statutory exemption before taking enforcement action, as lawful possession depends on permit status and exemptions.

Question 11: Why is core strength particularly important for CHP officers beyond what is measured in the sit-up test?

Core training is only relevant for officers assigned to K-9 units
Core strength primarily affects only the sit-up score on the PFE
Core strength supports posture, injury prevention, and performance in all physical tasks officers perform (Correct answer)
CHP officers rarely need core strength because patrol work is vehicle-based

Correct answer: Core strength supports posture, injury prevention, and performance in all physical tasks officers perform

A strong core stabilizes the spine during driving, foot pursuits, defensive tactics, and lifting, making it foundational to all officer duties.

Question 12: When is it legal to make a U-turn in California?

Only at traffic lights
U-turns are never legal
At intersections unless prohibited by signs, and in residential districts if no vehicle is within 200 feet (Correct answer)
Only on highways

Correct answer: At intersections unless prohibited by signs, and in residential districts if no vehicle is within 200 feet

California allows U-turns at intersections with adequate visibility unless signs prohibit them, and in residential areas when no approaching vehicle is within 200 feet.

The suspect's admission of drinking
A failed PAS test alone
The odor of alcohol alone
The totality of evidence including driving behavior, physical symptoms, and SFST performance (Correct answer)

Correct answer: The totality of evidence including driving behavior, physical symptoms, and SFST performance

Probable cause requires consideration of the totality of circumstances; no single factor alone is sufficient to meet the legal standard for arrest.

Question 16: At a T-intersection collision where Vehicle A ran a stop sign striking Vehicle B, which evidence is most important for establishing fault?

Witness statements, skid marks, point of impact location, and traffic control device violations (Correct answer)
The year of manufacture of Vehicle A
Whether either driver had received a prior traffic citation
The color of both vehicles

Correct answer: Witness statements, skid marks, point of impact location, and traffic control device violations

Establishing fault requires physical evidence showing traffic control violations, the point of impact location, and corroborating witness testimony about the event sequence.

Question 17: When parking uphill on a street WITHOUT a curb in California, which direction should the front wheels be turned?

Straight ahead
Either direction is acceptable
Toward the right (away from traffic) (Correct answer)
Toward the left (into traffic)

Detain the vehicle but must wait for a warrant before searching
Search only the specific area where paraphernalia was visible
Only cite the driver for the equipment violation

Correct answer: Search the entire vehicle if probable cause exists to believe it contains contraband

The automobile exception allows a warrantless search of the entire vehicle — including containers — when probable cause exists to believe it contains evidence of a crime.

Question 22: How many clues can a trained officer observe in the Walk-and-Turn (WAT) test?

4
6
10
8 (Correct answer)

Correct answer: 8

NHTSA identifies eight standardized clues in the WAT test; observing two or more clues indicates a likelihood of 0.08% BAC or higher.

Question 23: How do yaw marks differ from skid marks at a collision scene?

Yaw marks occur only on wet roads while skid marks occur only on dry roads
Yaw marks are from braking while skid marks are from acceleration
Yaw marks are curved marks from a rotating vehicle while skid marks are typically straight from locked wheels (Correct answer)
Yaw marks indicate sidewall contact while skid marks indicate flat-tire blowouts

Correct answer: Yaw marks are curved marks from a rotating vehicle while skid marks are typically straight from locked wheels

Yaw marks have a curved pattern caused by a vehicle sliding sideways, while skid marks are typically straight parallel lines from locked braking wheels.

Question 24: CHP's emergency vehicle operations training requires officers to demonstrate proficiency in which skill specifically related to pursuit driving?

Precision Immobilization Technique (PIT) (Correct answer)

Question 28: What physical evidence suggests a tire blowout may have caused a crash, as opposed to driver error?

Witness statements about loud music in the vehicle
Straight skid marks leading to the point of impact
Scattered tire tread fragments and an asymmetric yaw mark originating before the crash (Correct answer)
Damage confined only to the rear of the vehicle

Correct answer: Scattered tire tread fragments and an asymmetric yaw mark originating before the crash

Tire tread separation and a vehicle beginning to yaw before any apparent driver input suggests a sudden blowout caused sudden loss of vehicle control.

Question 29: What are the essential elements of a law enforcement report?

A brief summary is sufficient
Only what the officer remembers
Who, what, when, where, why, and how — documented factually and objectively (Correct answer)
Only the suspect's name

Correct answer: Who, what, when, where, why, and how — documented factually and objectively

Complete reports answer all fundamental questions with factual, objective, chronological documentation of observations, statements, and actions.

Question 30: An officer posts a social media message that disparages a protected group and mentions their CHP affiliation. This conduct:

Is fully protected as personal free speech under the First Amendment
Only becomes an issue if the post goes viral
Is only actionable if the officer identifies their patrol area
Can result in discipline because it undermines community trust and the officer's impartiality (Correct answer)

Correct answer: Can result in discipline because it undermines community trust and the officer's impartiality

Officers' social media activity that could reasonably harm public trust or imply bias can be subject to department discipline even when off duty.

Question 31: Some CHP officers are bilingual. All bilingual officers are assigned to border checkpoints. Officer Ruiz is assigned to a border checkpoint. What can be concluded?

Officer Ruiz is not bilingual
Officer Ruiz may or may not be bilingual (Correct answer)
Only bilingual officers are at border checkpoints
Officer Ruiz is definitely bilingual

Treating people fairly and with respect during encounters, regardless of outcome (Correct answer)
Increasing citation quotas to deter unsafe driving
Prioritizing officer safety over community engagement
Ensuring that guilty parties always receive maximum penalties

Correct answer: Treating people fairly and with respect during encounters, regardless of outcome

Procedural justice focuses on how people are treated during interactions, which builds legitimacy and public trust even when outcomes are unfavorable to the individual.

Question 64: A supervisor orders an officer to perform a search the officer believes is unconstitutional. The officer's ethical duty is to:

Transfer the duty to another officer without explanation
Perform the search since orders must be followed
Perform the search but do it quickly to minimize harm
Refuse and document the order and refusal (Correct answer)

Correct answer: Refuse and document the order and refusal

Officers must refuse clearly unlawful orders and document the refusal; following orders is not a defense for constitutional violations.

Additional training requirements and possible dismissal if minimum standards are not maintained (Correct answer)
Automatic reassignment to an administrative role
A pay reduction until standards are met
No consequences because the PFE is the only required fitness test

Correct answer: Additional training requirements and possible dismissal if minimum standards are not maintained

The CHP Academy maintains ongoing fitness standards, and recruits who fail to keep up may receive remedial training or face dismissal from the program.

Question 67: A CHP officer suspects a driver is under the influence of a CNS stimulant. Which sign would most support this conclusion?

Pulse rate below 60 bpm
Pupils dilated above 6.5mm (Correct answer)
Slow pupil reaction to light
Pupils constricted below 3mm

Correct answer: Pupils dilated above 6.5mm

CNS stimulants such as cocaine or methamphetamine cause pupil dilation (mydriasis), typically greater than 6.5mm in room-light conditions.

Question 68: A CHP officer accesses a confidential DMV record about a neighbor out of personal curiosity. This action is:

Acceptable if no information is shared with others
A violation of the Driver's Privacy Protection Act and department policy (Correct answer)
Only prohibited if the neighbor is a public figure
