HOW RADAR DETECTION WORKS IN YOUR TRAFFIC DEFENSE IN MISSOURI

Receiving a speeding ticket in Missouri can be frustrating, especially if you believe the radar gun used by law enforcement was inaccurate. Radar detection technology is commonly used by police officers to measure a vehicle’s speed, but errors can and do occur. Inaccurate radar readings can lead to wrongful traffic citations, and in some cases, a strong legal defense can result in a ticket being dismissed.
If you’ve been cited for speeding in Kansas City or anywhere in Missouri, understanding how radar detection works and its potential flaws can help in your defense. At KC Traffic Defense, our affordable traffic defense attorneys specialize in fighting traffic violations and ensuring your rights are protected.
HOW DO POLICE RADAR GUNS WORK?
Radar guns work by using radio waves to measure the speed of a moving vehicle.
Here’s how it works:
- The radar gun emits a radio signal that travels at the speed of light.
- The signal bounces off a moving vehicle and returns to the radar gun.
- The gun measures the change in frequency of the returning signal using the Doppler Effect, which allows it to calculate the vehicle’s speed.
While radar technology is widely used, it is not always accurate. A variety of factors can lead to false readings, which means your ticket may not be justified.
COMMON ISSUES WITH RADAR DETECTION
There are several ways radar readings can be inaccurate or unreliable, which may be used as a defense against a speeding ticket.
Interference from Other Objects: Radar guns can be affected by other vehicles, weather conditions, or even power lines. If multiple cars are on the road, the radar might register the speed of a different vehicle rather than yours.
Officer Error in Usage: Radar guns must be used correctly to provide an accurate reading. If the officer did not properly aim or calibrate the device, the reading may be unreliable.
Factors that contribute to officer error include:
- Not holding the gun steady
- Aiming at the wrong vehicle
- Operating the radar from an improper angle
Failure to Calibrate the Radar Gun
Radar devices must be regularly tested and calibrated to ensure accuracy. If the radar gun was not properly maintained or tested before use, the results may be flawed. Your attorney can request maintenance and calibration records as part of your defense.
Use of Moving Radar Systems
Some law enforcement agencies use moving radar, which allows officers to track speeds while driving. This method is more prone to errors, as the officer’s own speed must be accounted for. A slight miscalculation in the officer’s speed can result in an incorrect reading.
Cosine Effect and Angle Errors
If an officer uses radar at an angle instead of directly in front of or behind the vehicle, the radar may register a lower speed than the actual speed. However, in some cases, incorrect angles may increase the recorded speed, leading to an unfair citation.
HOW RADAR ISSUES CAN BE USED IN YOUR DEFENSE
If you have been ticketed for speeding, an experienced Kansas City traffic defense lawyer can use radar inaccuracies to challenge your ticket.
Common legal defenses include:
- Questioning the officer’s training and experience: Officers must be trained to properly use radar guns. If they lack proper certification, the radar reading may be challenged.
- Requesting radar calibration records: If the radar gun was not calibrated properly, the reading is unreliable.
- Challenging the radar’s accuracy: By presenting evidence of environmental interference or officer error, your lawyer can argue that the reading was flawed.
- Using witness statements or dashcam footage: If there is conflicting evidence, such as a dashcam showing a different speed, it can help disprove the ticket.
SHOULD YOU FIGHT A RADAR-BASED SPEEDING TICKET IN MISSOURI?
Many people assume that a radar-based speeding ticket cannot be challenged, but that is not true. If you pay the fine, you are admitting guilt, which can lead to increased insurance rates, points on your driving record, and potential license suspension.
- Fighting the ticket could help you:
- Avoid points on your license
