Which 10-CODE corresponds to 'Any traffic-security check'?

• A. 10-20
• B. 10-11
• C. 10-12
• D. 10-18

Answer: (D)

Focus on initiating and signaling a general traffic safety action. The code for a traffic-security check is used when you’re letting dispatch and other units know you’re conducting broad traffic safety enforcement—like vehicle checks, driver checks, sobriety checks, or similar traffic-focused enforcement efforts. It stands apart from simply reporting your location or other routine tasks, which is why it’s the best fit for this description.

The other options align with different, non–traffic-security actions or information (such as reporting a location or handling tasks unrelated to a broad traffic-enforcement check), so they don’t match the intent of conducting a traffic-security check. Keep in mind that 10-code usage can vary by agency, so it’s always good to confirm your specific unit’s codes.
