Drivers often hear that a speeding ticket based on radar can be beaten simply by demanding the calibration records and watching the case collapse when none exist. A 2012 Appellate Term decision shows why that strategy, on its own, usually doesn't work.
The Facts of the Case
Goess was charged with speeding in the Town of Philipstown, Putnam County. At trial, the arresting trooper testified to his qualifications: extensive practical training at the police academy, including hands-on practice visually estimating the speed of 500 vehicles, followed by 12 weeks of field training. Before starting his shift that day, he ran independent tuning fork tests on his radar unit and separately verified it against his own speedometer.
After observing Goess's vehicle for roughly 150 to 200 feet, the trooper visually estimated his speed at 70 mph in a 50 mph zone. The radar unit then registered 68 mph — a reading close enough to confirm the visual estimate. Goess was convicted after a nonjury trial and appealed, arguing that without formal calibration records, the radar reading couldn't establish his guilt.
The Question on Appeal
Does the absence of formal calibration records defeat a radar-based speeding conviction, even where the officer testifies to his own testing of the unit?
Case on Point
The Appellate Term held that calibration records are not needed to establish a radar device's accuracy. A device's accuracy can instead be established by proof that a qualified radar operator conducted tests indicating the unit was functioning properly at the time of the incident. Because the trooper testified he'd conducted the appropriate tuning fork and calibration tests, and the prosecution introduced his radar operation certificate, the evidence was independently sufficient to sustain the conviction.

The Fallback the Court Didn't Even Need
The court didn't stop at finding the radar testing adequate. It went further, noting that even if the calibration proof had been inadequate, an untested radar reading paired with a qualified officer's visual estimate would have been enough on its own to sustain the conviction. In Goess's case, that fallback was easy to apply — his visual estimate of 70 mph and the radar's reading of 68 mph were close enough to corroborate each other.
Key Takeaway: Goess shows two independent paths to a valid conviction: a properly tested radar unit, evidenced by the officer's own testimony rather than paperwork; or, failing that, radar corroborated by a qualified visual estimate. A defense built only around "there's no calibration record" leaves both paths open for the prosecution.
What This Means for a Defense
Goess points toward the questions that actually matter in a radar case, rather than the ones that sound persuasive but aren't:
- Did the officer describe a real test, in detail? The record here included specific testimony about tuning fork and speedometer checks — not just a claim that the unit was "working fine."
- Was the officer's training and certification actually established? The prosecution introduced the trooper's radar operation certificate and testimony about his academy and field training — gaps in either would have mattered more than a missing calibration record.
- Is there a visual estimate in the mix? Because the visual estimate closely matched the radar reading, even a successful attack on the radar testing wouldn't have been enough by itself to undermine the conviction.
