Do cops have to show you the radar?

We’ve all been there – cruising comfortably along the highway when suddenly there are flashing lights in the rearview mirror. You pull over and a police officer approaches, notifying you that you were exceeding the speed limit according to the radar gun readout. But do law enforcement officers actually have to show you the radar evidence used to write you a potential costly speeding ticket?

Do police have to show you their radar reading?

While it would provide helpful proof when challenging a speeding citation in court, there are no federal or state laws requiring police to show drivers the actual radar gun speed readings during a traffic stop. However, many individual police departments now have policies requiring officers to show the radar gun evidence and allow drivers to see the speed detected upon request.

Why do some cops refuse to show the radar evidence?

There are a few reasons an officer may decline to show drivers the actual radar gun readout:

Officer Safety

Having to show drivers the radar display could create unsafe proximity during traffic stops. As officer safety is paramount, avoiding close-up confrontations outweighs transparency in some cases.

Preventing Roadside Debates

Displaying the radar reading opens up debates about its accuracy at roadside which delays traffic stops. To keep the roadways safe, officers want to conclude stops efficiently before issuing citations.

What can you do if a cop doesn’t show the radar evidence?

If an officer refuses to show you the radar evidence, remain calm and cooperative even if you disagree about speeding. Arguing with police at roadside rarely ends well for drivers. Instead, you can fight an unfair ticket through the court system at a later date by:

Contesting the Ticket

You can enter a not guilty plea and request a trial to contest the speeding ticket where you can request to examine documentation like radar equipment logs and calibration records.

Hiring a Traffic Lawyer

An experienced traffic attorney understands radar operation and calibration requirements. They can obtain documentation and question the officer’s training to fight a speeding ticket without radar evidence.

Tips for Beating a Speeding Ticket

If you do intend on contesting that questionable speeding citation, here are some additional tips to help fight the ticket:

  • Check Officer Training/Certification – Ensure the officer meets state requirements for operating radar equipment.
  • Note Weather Conditions – Rain, wind, temperature inversions can all impact radar accuracy.
  • Question Visual Estimates – Radar readings can reinforce visual speed estimates which are subjective.
  • Inspect Equipment Records – Examine radar calibration documents and logs for procedural violations.

Having an experienced traffic lawyer request these items can help beat tickets issued without valid radar evidence.


While officers have full discretion whether or not to show you actual radar gun readings during a traffic stop, having policies requiring this transparency are becoming best practices. As frustrating as it is receive a speeding citation without seeing the radar evidence, the best recourse is to comply at roadside then fight the unfair ticket in court.
