The lights hit your mirror, you find a wide shoulder, and by the time the officer reaches your window you have already rehearsed the conversation three times. Then comes the oldest question in American traffic enforcement. Do you know how fast you were going? The instinct for most drivers is a shrug and a very honest sounding “I’m not sure.” That shrug is the most expensive thing you can say at a traffic stop, because it hands the officer the number and leaves you nothing to argue with later.
“Never say ‘I don’t know’ because then you are relying on the officer to be truthful about the speed you were going,” says Patrick Buelna, a civil rights attorney who specializes in law enforcement misconduct and a partner at Pointer and Buelna in Oakland, California. Once you have admitted you were unaware of your own speed, he says, you have no way to rebut whatever figure the officer names.
That figure is not a small detail. It sets the fine, it decides how many points land on your license, and it follows you onto your auto policy for years.
The Eight Words Attorneys Keep Repeating
Mike Mandell, a Duke law graduate who practices in California and posts as @LawByMike to more than 10 million TikTok followers, tells his audience there is only one correct response to the speed question: “I believe I was going the speed limit.”
Buelna, speaking to Reader’s Digest, calls that the best answer available, and the whole thing turns on a single word. “The most important word in that sentence is believe because it suggests you were in the speed limit yet leaves open the possibility that you could be wrong,” he says. You have not confessed, and you have not lied, which matters because a flat denial that turns out to be false creates its own problems.
Firms that handle traffic cases push the same script for the same reason. It admits nothing, denies nothing, and keeps every option open for the day you decide to fight the citation.
Some Defense Lawyers Say Just Answer Yes
Not every attorney agrees on the wording. Another camp says the right answer to “Do you know how fast you were going?” is one word: yes. Nothing else. The officer will probably tell you the number, and at that point you do not argue. A little reflective listening covers it: “Hmmm,” “I see,” “I understand,” and nothing with any substance in it.
Both scripts exist for the same reason. Saying no, or I don’t know, tells the officer you were not paying attention to your own speed, and every driver is expected to. It also strips away your standing to dispute the reading. The disagreement is over style. The agreement is that the shrug loses.
A Different Question With the Opposite Answer
“Do you know why I stopped you?” is not the same question, and it gets the reverse answer. If you answer at all, the answer is no. Say yes and you have volunteered to describe your own violation before the officer has committed to one.
There is a nastier version of the same trick. If an officer asks whether there is some reason you were in such a hurry that you had to speed, the answer is no. Saying yes is an admission that you were speeding, even if you were not, and it will almost certainly produce a ticket.
An Apology Is a Confession With Better Manners
Defense lawyers will tell you officers routinely act as though a warning is on the table, but only if you cooperate and answer their questions. The friendly opening is part of the job. It invites you to explain yourself, and explanations are evidence.
So the sentence that feels most decent is the one that hurts you most. “Yes, officer, I know I was speeding, but I promise to be more careful next time” is only an admission of guilt. Officers also fish for a different concession, that you were not paying attention. The less you say, the less there is to read back in court.
The Fifth Amendment Works on the Shoulder, but You Have to Say So
Most people file the right to remain silent under courtroom drama. It is broader than that. The Bill of Rights says no person “shall be compelled in any criminal case to be a witness against himself,” and the protection is not confined to a criminal courtroom. What it does not do is work by itself on the shoulder. In Berkemer v. McCarty the Supreme Court held that a routine traffic stop is not custody, so no warning is owed and what you say there is admissible. In Salinas v. Texas it declined to protect a man who simply went quiet when the questions got difficult, because he had never said he was invoking the Fifth.
Innocent people can invoke it, and often should. In Ohio v. Reiner, a father convicted of involuntary manslaughter over the death of his two-month-old son argued that the family’s babysitter had caused the injuries; the boy’s twin brother had broken ribs as well. The babysitter maintained her innocence and moved to assert her Fifth Amendment right anyway, because facts she would have had to admit, such as being alone with the children, could later be used against her. The Supreme Court held she was entitled to, in a ruling that says plainly the privilege protects the innocent as well as the guilty.
The protection has edges. It is for a real risk of prosecution rather than for not fancying the question: the test, borrowed from an 1861 English case, carried into American law by Mason v. United States and quoted again in Reiner, is that a danger of “imaginary and unsubstantial character” will not do. Someone who happened to watch a car crash at an intersection cannot refuse to testify about it. And at a stop, going quiet is not by itself enough. If you mean to rely on the Fifth Amendment, say out loud that you are.
Where You Pull Over Can Help You in Court
Signal, slow down, move right and stop as soon as you safely can, ideally a close parking lot or a wide shoulder. Stopping quickly also fixes the location in both your minds. You can drive back later and look at the spot yourself, including whether the officer had the sight lines to measure your speed the way the citation claims.
The rest is choreography. Put it in park, roll the driver’s window all the way down, tinted windows too, shut off the ignition, and rest your hands on top of the wheel where they are visible. At night, turn on the interior light. Do not go digging in the glove box before you are asked, and do not shove anything under the seat. A furtive motion is not probable cause on its own, but courts do count it toward the totality an officer may act on, and it is free suspicion you have handed over. When the license and registration are requested, “Sure” or “Of course” is a complete sentence.
Never Agree to a Search, Even With Nothing to Hide
An officer who has legitimate grounds to search your car will search it whether you agree or not. That is why the request itself is worth noticing. And under Schneckloth v. Bustamonte an officer is not required to tell you that you can say no. Whether you knew you could refuse is a factor a court weighs, not something the state has to prove.
Consenting also costs you later. Evidence found in a car you agreed to let them search is much harder to challenge. Contraband sitting in plain view is a different matter, and so is probable cause built from what an officer can see, hear or smell during the stop.
The Fine Is the Cheap Part of a Speeding Ticket
A LendingTree study published in November 2025 found that drivers pay an average of 22.7% more for auto coverage after a ticket for going 11 to 15 mph over the limit. That works out to $524.74 more a year, or $43.73 a month. Stretched across three years, it is $1,574.22 in extra premiums.
California drivers get hit hardest in percentage terms, with average rates climbing 42.0%, from $2,392.91 to $3,397.64. Arizona and California are the only two states where the average increase tops $1,000 a year, at $1,071.41 and $1,004.73. Vermont is the mildest at $225.40. Age matters more than the percentages suggest: a 20 year old’s premium jumps an average of $1,183.67 a year, against roughly $550 for drivers in their 50s and 60s.
The industry has a name for it. “The rate increase you get for speeding or other moving violations is called a surcharge,” says Rob Bhatt, a licensed insurance agent and insurance expert at LendingTree, who notes that carriers treat a ticketed driver as a higher crash risk than one with a clean record. Then there are points. LendingTree puts the typical hit at two to four for speeding 10 to 15 over, but the scales vary and California assigns a single point. Hawaii, Kansas, Louisiana, Minnesota, Mississippi, Oregon, Rhode Island, Texas, Washington and Wyoming do not use points at all, counting convictions instead.
In California and Texas, Over the Limit Is Not Automatically Illegal
Speed limits come in three flavors in American law, and the one you are accused of breaking decides your entire defense. Absolute limits leave no room: 41 mph in a 40 zone is a violation, period. Presumed limits, used in states including California and Texas, treat going over the posted number as presumed unsafe, which means the presumption can be rebutted if you can show conditions were safe. California is only a partial example, since its 65, 55 and 70 mph maximums are absolute and no amount of good weather rebuts those. Basic speed law cuts the other way, and you can be cited for 65 mph on a freeway in fog, though in practice police reach for it after a crash rather than before one.
How your speed was measured is the other opening. Pacing, aircraft, radar, LIDAR and VASCAR each have their own weak points. What does not work is pleading ignorance, since drivers are expected to know the traffic laws, or hunting for a typo, because a misspelled name on a citation usually changes nothing. Judges and prosecutors in traffic court have heard the invented family emergency before. Traffic school, on the other hand, can keep the point off your record in many states. It does not cancel the fine, and the course costs money on top of it. California allows it once every 18 months.
The Line Worth Memorizing
Pick whichever script you can deliver without your voice shaking. “I believe I was going the speed limit” is the stronger of the two, because it costs you nothing, gives the officer nothing, and leaves the number an open question you can still fight over. What you cannot afford is the answer that feels most modest and most polite, the one where you admit you were not watching the needle.
If the ticket comes anyway, take it politely and stop talking. Arguing on the shoulder has never reduced a fine. The place to contest a ticket is traffic court, and how carefully you handled those four minutes at the window decides how much of a case you still have when you get there.
