Quick answer: If you believe the speed on your Maryland citation is wrong, saying “I wasn’t going that fast” is not a defense by itself. What works is attacking the measurement — how the officer clocked you, whether the equipment was calibrated, whether the officer was certified, and whether conditions allowed an accurate reading. A denial rarely moves a judge; an evidentiary challenge to a radar, LIDAR, or pacing reading is how these cases get reduced or dismissed.
I’m David Waranch, and I’ve handled thousands of Maryland speeding and traffic cases. Drivers routinely misjudge their own speed by 5 to 10 mph, and officers and their equipment can also produce readings that don’t match reality. The question a District Court judge answers is not who feels right — it’s what the evidence shows. Here’s how to make the evidence work for you.
Why “I Wasn’t Going That Fast” Alone Doesn’t Work
Maryland judges hear “I wasn’t going that fast” every single day. Without supporting facts, it’s a denial, and denials don’t win. The State puts on the officer, the citation, and usually testimony about how the speed was measured. Your memory that you were going slower carries almost no weight against a calibrated device and a certified operator, no matter how sure you are.
The version that actually works isn’t “the officer was wrong.” It’s “the State can’t prove the alleged speed to the standard the law requires.” That reframing turns a denial into an evidentiary challenge, and evidentiary challenges are how Maryland speeding cases get won or knocked down. For the honest odds, see why it’s so hard to beat a Maryland speeding ticket — this page is about doing it right when the number really is off.
How Maryland Officers Actually Measure Your Speed
Almost every officer-issued speeding case rests on one of three methods, and each has documented weak points a defense can examine.
| Method | How it works | Where it breaks down |
|---|---|---|
| Radar | Microwave Doppler shift; unit tested with calibrated tuning forks before and after each shift | Other moving objects in the beam, multiple targets, electrical interference, angle “cosine error,” missing calibration logs |
| LIDAR (laser) | Narrow infrared beam isolating one vehicle; needs steady aim and alignment | Rain and fog degrade accuracy; improper aim point; alignment and calibration gaps |
| Pacing | Officer matches your speed and reads the patrol car’s speedometer | Speedometer not calibrated, inconsistent following distance, intervening traffic, pacing distance too short |
Each method has its own mechanics and its own openings. Dig into how radar speeding tickets work in Maryland, how LIDAR speeding tickets work, and how pacing speeding tickets work. Pacing is often the weakest of the three, because real traffic disrupts at least one of its requirements more often than not.
What Evidence Actually Challenges a Speed Reading
A real challenge is built on documents and records, not on your recollection of the speedometer. Four categories carry the weight:
- Calibration logs and tuning-fork tests. Radar units are supposed to be tested with calibrated tuning forks at the start and end of each shift, and the forks themselves must be periodically recertified. Missing, incomplete, or inconsistent logs make the reading vulnerable. Counsel can request these in discovery.
- Officer certification records. The officer must have current radar or LIDAR operator certification. If it was expired at the time of the stop, or the training didn’t cover the technology used, the reading is open to attack.
- Line of sight and positioning. A stationary radar reading taken from behind a curve, over a hill, or through vegetation can be challenged on angle and visibility. Cosine error — a sharp angle between the beam and your direction of travel — usually reads low, in the driver’s favor, but positioning cuts both ways.
- The officer’s own notes. A thin tracking history, an unclear description, or a long gap between the reading and the stop all create room on cross-examination. Officers frequently can’t recall the specifics of a routine stop months later.
Don’t just pay it because you can’t prove your number. Paying a Maryland speeding ticket is a guilty plea and puts a conviction and points on your record. Requesting a trial or a waiver hearing costs nothing extra beyond the ticket and keeps a non-conviction on the table — including probation before judgment under Crim. Proc. § 6-220, which carries no points and is foreclosed the moment you pay. A hearing isn’t free, though: a judge can raise the fine up to $500, so treat it as a trade-off you get to make.
When the Number Straddles the Reckless Threshold
The highest-stakes version of “I wasn’t going that fast” is when the alleged speed sits in the 28-to-32-mph-over range. Under Md. Code, Transp. § 21-901.1(a), driving at least 30 mph above the posted limit is reckless driving — a criminal, must-appear charge carrying up to 60 days in jail and 6 points. Ordinary speeding 10 to 29 mph over is a payable, 2-point violation. So the gap between an alleged 28 over and an alleged 30 over is the difference between a traffic fine and a criminal record.
If your case is in that borderline band, even a modest challenge can matter enormously — knock the proven speed below 30 over and the reckless charge disappears. See the exact Maryland speeding penalties by speed range and the jail exposure for reckless driving to see what’s on the line.
Why You Genuinely Feel You Weren’t Going That Fast
Speed perception is shaped by things that have nothing to do with the speedometer. Modern cars are quieter and smoother, so 75 feels like 60 used to. Familiar routes and light traffic feel slower than new roads and packed lanes at the same speed. Wide, straight highways feel slower than narrow or curving ones, and downhill grades add real speed most drivers never notice. None of that means you’re lying — it means your feeling isn’t strong evidence against a documented measurement, and the documentation wins unless the documentation itself has a problem. That’s exactly why the records matter more than the memory.
Realistic Outcomes From a Speed Challenge
When the evidence genuinely supports a challenge, the usual result is a reduction or probation before judgment, not an outright dismissal. Dismissals do happen — a missing calibration log, a lapsed certification, or an officer who doesn’t show — but they’re the exception. More often, legitimate doubt about the reading creates leverage: the prosecutor may reduce a higher-speed charge to one with fewer points, and a PBJ becomes easier to reach once the State sees the number might not survive cross-examination. Fewer points protects your license under Maryland’s point system, where 8 points in two years means suspension. For the full framework, see whether you can fight a Maryland speeding ticket in court.
What Not to Do
Three moves fail consistently. First, telling the judge “I wasn’t going that fast” with nothing behind it — the judge has heard it hundreds of times. Second, arguing speed with the officer at the roadside; it rarely changes the stop and gives the State material about your demeanor for sentencing. Third, paying the ticket because it “seemed too high to fight” — that’s a conviction, the points stick, and the insurance increase follows. And note that “everybody else was speeding too” is not a defense in Maryland — the posted limit is absolute.
If you believe the speed on your citation is wrong, the path forward is the actual evidence — calibration logs, officer certification, line of sight, and conditions. A Maryland speeding ticket lawyer can pull those records and tell you honestly whether a reduction, a PBJ, or a dismissal is realistic.

Not on its own. A bare denial does not persuade a judge against a calibrated device and a certified officer. What works is challenging the measurement itself: the calibration records, the officer’s certification, the line of sight, and the conditions at the time of the stop.
Yes. Radar and LIDAR calibration logs, tuning-fork recertification records, and the officer’s operator certification are all obtainable through discovery. Missing, incomplete, or expired records are the openings that make a speed reading vulnerable to challenge.
The most common results are a charge reduction or probation before judgment, not an outright dismissal. Raising legitimate doubt about the reading creates leverage to negotiate fewer points, and a PBJ under Crim. Proc. section 6-220 keeps a conviction off your record. Dismissals happen mainly when records are missing or the officer does not appear.
