Question 1
What does code 10-63 indicate?
Correct Answer:
Subject Positive Hit
Explanation:
The idea being tested is that this code communicates a definite identification. When you hear 10-63, it means your records check on the person you’ve encountered produced a positive match—someone who is wanted, has an outstanding order, or is otherwise flagged in the system. That tells you the subject is not just a possibility; there’s a confirmed lead you must act on. Operationally, this prompts you to verify the person’s identity, notify dispatch, and likely take appropriate action with added caution and, if needed, backup. The other options describe general actions or unrelated services (like towing or medical help) and don’t convey that you’ve confirmed a match in the records.
Question 2
What does code 10-20 indicate?
Correct Answer:
What is your location?
Explanation:
In police radio communication, the 10-series codes are used to convey common information quickly. The code 10-20 stands for location, so it signals that the speaker is asking for or reporting their whereabouts. That’s why the option that matches the idea of asking for or stating one’s location fits best. The other phrases describe things like dispatch timing, a status of officials, or weather/road information, which aren’t what 10-20 signifies.
Question 3
Which 10-code indicates information is not according to regulations?
Correct Answer:
10-42 Not According to Regulation
Explanation:
Not following regulations is signaled by a code whose message is Not According to Regulation. This code is used to flag information or actions that aren’t in line with policy, prompting a review or correction before proceeding. The other options describe specific situations—a drunk person, a death, or an investigation alert—which refer to particular incidents or statuses, not to non-compliance with regulations. So the code that explicitly indicates information isn’t according to regulation is the correct choice.
Question 4
What code should you use to momentarily stop transmitting while keeping the channel active?
Correct Answer:
Stop Transmitting
Explanation:
In radio discipline, there are times you need to pause your own transmission briefly so others can speak or you can listen, while the channel itself stays open for ongoing communication. This is exactly what the Stop Transmitting code does: it tells everyone on the air that you’re momentarily not speaking, but you’re remaining on the channel to hear responses and keep the conversation active. Relaying would shift the transmission to another unit, which isn’t about pausing your own speech while keeping the channel live. In Service just notes your status as available, not a command to pause. Repeat asks for the last message to be sent again, not for a brief transmission pause.
Question 5
When should backup be requested during a traffic stop?
Correct Answer:
If there are risk factors such as unknown weapons, hostile or evasive behavior.
Explanation:
During a traffic stop, officer safety hinges on evaluating risk and being prepared to respond. If there are risk factors, such as unknown weapons or hostile or evasive behavior, requesting backup is the prudent, proactive choice. Having additional officers provides protection, better control of the scene, and more options if the situation escalates, which is why this is the best approach. A driver speaking loudly isn’t a reliable sole indicator of danger, and waiting to call for backup only after the suspect exits can leave you exposed if threats materialize during the stop. Also, assuming backup is never needed for routine stops ignores the reality that even ordinary stops can turn risky if factors arise.

About this Exam

Police 10 codes are the standardized radio communication codes that form the essential backbone of information exchange for law enforcement professionals across Ontario. This comprehensive practice guide is specifically designed for aspiring applicants and recruits preparing to join the Ontario Provincial Police (OPP).

The [OPP 10 Codes Practice Exam] serves as a crucial bridge between theoretical knowledge and the high-stakes, real-world communications used daily on patrol and in dispatch centers. It is an invaluable resource for anyone preparing for the official assessments administered during OPP recruit or civilian communications training, offering a simulated environment to test their recall accuracy and speed.

Additional Information

What the Course Entails and Exam Details

While not a standalone "course" in the traditional sense, mastery of the OPP 10 codes is a prerequisite skill taught and assessed within official training curriculums for OPP Constables, Special Constables, and Communications Operators. The syllabus consists of the entire official OPP list of radio codes, ranging from common acknowledgments to critical emergency alerts.

Key components covered in preparation for the assessment include:

  • Memorization: Rote learning of the precise numeric code (e.g., 10-4) and its exact official meaning (e.g., Acknowledged/OK).

  • Auditory Recognition: Developing the ability to instantly recognize codes when heard over radio static or in busy environments.

  • Scenario Context: Knowing which code to apply quickly and correctly in a variety of situational scenarios, such as reporting a traffic accident, requesting assistance, or initiating a pursuit.


What to Expect in the Final Exam

It is important to understand that there is no single external "final exam" for 10 codes that grants a public certification. Instead, this practice test prepares you for the high-standard assessments that are integral parts of employment training within the OPP. Candidates can expect these formal internal exams to be both challenging and time-sensitive to simulate field conditions.

The likely format for these assessments includes:

  • Format: A combination of multiple-choice questions, fill-in-the-blank definitions, and auditory recognition components. You may listen to a recording of a code and must select its meaning, or be given a situation and must provide the correct code.

  • Passing Score: Due to the critical nature of accurate communication for officer and public safety, the passing standard is set exceptionally high, typically requiring a score of 90% or greater.

  • Time Limits: To emphasize the need for rapid, instinctive recall, the assessments are timed, giving you minimal thinking time per question.

  • Rules: Official exams are taken without aids, including notes or lists, under the supervision of training officers or instructors.


How to Study and Exam Centers

Effective study strategies are crucial for achieving the near-perfect recall demanded by the OPP. You are encouraged to use repetitive and varied methods to reinforce learning:

  • Actionable Study Strategies:

    • Active Recall with Flashcards: Create or use digital flashcards to drill codes and meanings in both directions.

    • Auditory Drills: Record yourself or a partner saying the codes and practice identifying them by ear, and vice-versa.

    • Scenario-Based Practice: Simulate field calls with another person, using 10 codes in context to build practical application skills.

    • Frequent, Short Sessions: Engage in daily, short study bursts rather than infrequent, long cramming sessions.

  • Where to Take the Exam: As an internal component of OPP training, the formal assessments are not taken at external, public testing centers like Pearson VUE. Candidates will take these tests at official, designated training locations once they are employed or have been accepted into a training program. These locations include:

    • Ontario Police College (OPC): For OPP recruits undergoing basic constable training.

    • OPP Regional Headquarters or Communications Centres: For civilian staff training to be Communications Operators or Dispatchers.
