Hm, now that leaves open the fact that the misuse at night would still be a violation. See how much fun the law can be? šŸ˜ƒ ---

According to Eugene Volokh in _Crime-Facilitating Speech_, > [@](#): > > Some speech provides information that makes it easier for people to commit crimes, torts, or other harms. Consider: > > (a) A textbook, magazine, Web site, or seminar describes how people can make bombs (conventional or nuclear), make guns, make drugs, commit contract murder, engage in sabotage, painlessly and reliably commit suicide, fool ballistic identification systems or fingerprint recognition systems, pick locks, evade taxes, or more effectively resist arrest during civil disobedience. > > (b) A thriller or mystery novel does the same, for the sake of realism. > > (c) A Web site or a computer science article explains how messages can be effectively encrypted (which can help stymie law enforcement), how encrypted copyrighted material can be illegally decrypted, what security flaws exist in a prominent computer operating system, or how computer viruses are written. > > (d) A newspaper publishes the name of a witness to a crime, thus making it easier for the criminal to intimidate or kill the witness. > > (e) A leaflet or a Web site gives the names and possibly the addresses of boycott violators, abortion providers, strikebreakers, police officers, police informants, anonymous litigants, registered sex offenders, or political convention delegates. > > (f) A Web site posts peopleā€™s social security numbers or credit card numbers, or the passwords to computer systems. > > (g) A newspaper publishes the sailing dates of troopships, secret military plans, or the names of undercover agents in enemy countries. > > (h) A Web site or a newspaper article names a Web site that contains copyright-infringing material, or describes it in enough detail that readers could quickly find it using a search engine. > > (i) A Web site sells or gives away research papers, which helps students cheat. > > (j) A magazine describes how one can organize oneā€™s tax return to minimize the risk of a tax audit, share music files while minimizing the risk of being sued as an infringer, or better conceal oneā€™s sexual abuse of children. > > (k) A newspaper publishes information about a secret subpoena, a secret wiretap, a secret grand jury investigation, or a secret impending police operation, and the suspects thus learn they are being targeted; or a library, Internet service provider, bank, or other entity whose records are subpoenaed alerts the media to complain about what it sees as an abusive subpoena. > > (l) When any of the speech mentioned above is suppressed, a self-styled anticensorship Web site posts a copy, not because its operators intend to facilitate crime, but because they want to protest and resist speech suppression or to inform the public about the facts underlying the suppression controversy. > > (m) A master criminal advises a less experienced friend on how best to commit a crime, or on how a criminal gang should maintain discipline and power. > > (n) A supporter of sanctuary for El Salvadoran refugees tells a refugee the location of a hole in the border fence, and the directions to a church that would harbor him. > > (o) A lookout, a friend, or a stranger who has no relationship with the criminal but who dislikes the police warns a criminal that the police are coming. > > (p) A driver flashes his lights to warn other drivers of a speed trap. > > These are not incitement cases: The speech isnā€™t persuading or inspiring some readers to commit bad acts. Rather, the speech is giving people information that helps them commit bad acts - acts that they likely already want to commit. > > When should such speech be constitutionally unprotected? Surprisingly, the Supreme Court has never squarely confronted this issue, and lower courts and commentators have only recently begun to seriously face it. And getting the answer right is important: Because these scenarios are structurally similar - a similarity that hasnā€™t been generally recognized - a decision about one of them will affect the results in others. If a restriction on one of these kinds of speech is upheld (or struck down), others may be unexpectedly validated (or invalidated) as well. 57 Stan. L. Rev. 1095 (2005) In a footnote, Volokh notes: > [@](#): > > This is tantamount to the driverā€™s acting as a lookout, see supra notes 37-39: It lets the other drivers drive illegally before and after the speed trap without getting caught, because they have been warned to obey the law when the police are watching. See State v. Walker, No. I-9507-03625 (Williamson Cty. (Tenn.) Cir. Ct. Nov. 13, 2003) (accepting a First Amendment defense in such circumstances); For the Record, Salt Lake Trib., Feb. 29, 2000, at B2 (noting a similar case in which a First Amendment defense was accepted); cf. Bucher, 375 F.3d at 930 (noting the First Amendment question); Commonwealth v. Beachey, 728 A.2d 912 (Pa. 1999) (considering a similar case, but not confronting the First Amendment question) ---

[QUOTE=Philster] In NJ, USA, itā€™s now illegal to flash your headlights. [/QUOTE] Sure about that? I distinctly remember when it was ruled _legal_ here, but have not heard anything about that being overturned. A Factiva search brought up only two Jersey-based articles on the subject, both many years old: > [@](#): > > \*\*News flash: Tipoffs to speed traps are legal - Court says blinking headlights okay \*\* > \*Robert Schwaneberg and Michaelangelo Conte \* > 31 July 1999 > The Star-Ledger Newark, NJ > > It happens every day on New Jerseyā€™s highways: Someone drives past a patrol car lurking in the bushes and flashes his headlights to warn oncoming drivers to slow down. > > To many it is a natural, neighborly gesture they would expect in return; to others, an underhanded way of subverting the efforts of police.

But that law ā€œwas never intended to prohibit a motorist from warning oncoming motorists that a speed trap lies ahead,ā€ a state appeals court ruled this week. > > The two judges who heard the case concluded ā€œthat a motorist may not be convicted of misusing her headlights to warn oncoming motorists of radar.ā€ > > _\_ > > The ruling resulted from the case of Susan Luptak of Jackson Township, who passed a patrol car in Monroe Township and flashed her headlights at an oncoming driver.

My stepfather passed a speed trap. A mile or so down the road, a semi is barrelling through in the other direction. Stepdad gives a friendly flash of lights. Just as he does so, he sees a police car cruising behind the semi. Cop slows, u-turns, and the lights come on. Stepdad: Yes, constable? Cop: I just saw you flash your lights at that truck. Stepdad: Yes. Cop: Are you aware there is a police radar unit in operation two kilometres back? Stepdad: Aahā€¦ I might have seen something like that, yes. Cop: Are you aware that is is an offence to distract other drivers? Stepdad: (thinking quickly) I was aahā€¦ letting him know heā€™d left his headlights on! Cop: (obviously trying to remember if heā€™d seen the truckā€™s taillights or not) Drive safely sir. Good day. ---

A couple of (rather out of date) UK cases: [here](http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2004/06/03/ncam03.xml&sSheet=/portal/2004/06/03/ixportal.html) and [here](http://news.bbc.co.uk/1/hi/england/somerset/4338972.stm). In the first, a man was convicted of ā€œwilfully obstructing a constable in the execution of his dutyā€, while in the second the conviction (in a different case) was overturned on appeal, because it could not be proved that the apellantā€™s actions caused anyone to slow down. Anyway, it seems that if you do this in the UK, you do risk prosecution, though it is rare for such cases to go to trial. ---

[QUOTE=Elendilā€™s Heir] In 15 years of criminal and traffic practice in Ohio, including five years as a magistrate handling (among many other things) traffic cases, Iā€™ve never heard of anyone ever actually being cited for flashing a speed-trap warning to other motorists. Iā€™m aware of no Ohio law that would prohibit such a warning. That said, I wouldnā€™t be surprised to learn that some annoyed cops will warn or chew out motorists who do it. [/QUOTE] As several of our respondents from other states have noted, the story I always heard regarding the Ohio law was that the citation would be given for ā€œinterfering with a police officer,ā€ but also like you, I cannot recall anyone actually busted for the offense. I am disinclined to do the flashing bit, anyway, (if it is a local road, I would just as soon they were not blowing the speed limit and if it is a freeway, I doubt that a speeder would recognize my flash of lights as a warning). On the other hand, I have several times flashed my lights after passing an accident so that they will slow down and begin watching the road more closely, looking for the cop but spotting the accident. ---

If the legislature intended to prohibit the type of activity that appellant was engaged in, the grammatically correct way to express that intent would be to say: ā€œThe flashing of oneā€™s headlights is prohibitedā€ rather than ā€œflashing lights are prohibited.ā€ It is the lights themselves, rather than the act of flashing oneā€™s lights, that are the subject of the prohibition. > > Furthermore, the ordinance in question is titled, ā€œLimitation on Flashing, Oscillating or Rotating Lights.ā€ The ordinance prohibits flashing lights on all vehicles except emergency vehicles and various other specialty vehicles such as snow plows, rural mail delivery vehicles, and funeral escort vehicles. It is clear that all of the vehicles that fall within the exception to the general prohibition utilize roof-mounted lights that flash, oscillate or rotate. Therefore, the implication is that the prohibition is aimed towards the use of similar roof-mounted lights on ordinary passenger vehicles. > > To read the ordinance in accordance with appelleeā€™s argument would make illegal the flashing of headlights in all situations, including some useful and historically lawful instances. For example, the flashing of headlights can be used to signal another driver to turn on his or her headlights. The flashing of headlights is also used on highways to let the driver of a passing vehicle know that it is safe to move back into the right-hand lane. It is doubtful that the flashing of headlights in these examples was intended to be outlawed by the legislature, but that is exactly the result if appelleeā€™s argument is accepted. > > **We note that Ohio courts have previously held that the act of flashing oneā€™s headlights so as to alert oncoming drivers of a radar trap does not constitute the offense of obstructing a police officer in the performance of his duties, where there was no proof that the warned vehicles were speeding prior to the warning.

I tend to think, that as usual, the more ignorant/stupid cops will you pull you over, _assuming_ some perceived infraction. Usually, after they illegally search your car, theyā€™ll let you go. Unless, of course, you refuse the drug search. Then they call the dog unit, you get frustrated while they berate you like a criminal for another hour, and then they show up and find nothing. Then they get all pissed off and become hardasses about ā€œwarning other motoristsā€. Also in certain areas your Blackness may come into account :smack: ā˜¹ Itā€™s possible you could recieve day or two in jail, and ā€œon monday, when the judge gets backā€, you get released.

It depends on the jurisdiction and whether or not there is a law against that activity. The flashing of lights would be easier to enforce than a ā€œfree speechā€ sign, I would think. Where I lived until a year ago, the police would place a notice in the newspaper about where they would be doing radar that day or that week and they still reaped in the bucks from the speeders. They also would hide in big cardboard boxes and shoot thru a hole in it and they would get up over the road in a bucket truck and wear hard hats as disguises, with ā€œchaserā€ cars downstream. Perfectly legal. Fun, fun, fun. ---

In short, from what we have seen, everyone has heard of this assertion by police officers, many have experienced it directly, but whenever it ends up in court, the courts recognize it for what it is and disallow it. I have never thought it necessary to warn someone of a ā€œspeed trap.ā€ After all, if they are going so fast that they will end up caught and ticketed by radar, Iā€™d rather they get caught and ticketed, as opposed to facilitating their lawlessness. And I always remember that the reason someone flashed at me was an officer ahead only when I see the officer ahead. But, then, speed traps donā€™t ever bother me, because I remain within (or very close to) the speed limit. Which, I do understand, makes me a member of a very small minority of drivers. šŸ™‚ ---

Iā€™m hoping those that contributed to this thread are still subscribed in some form. I can assure you Florida Highway Patrol has an active policy to cite drivers who warn others of police radar. I just go popped earlier this month. The officer did not know that I had the entire incident recorded (video and audio). A link to the stop is here: [![](https://img.youtube.com/vi/Ed7xiZeWrYk/hqdefault.jpg "Cop issues ticket for warning others of speed trap") ](https://www.youtube.com/watch?v=Ed7xiZeWrYk) For those that think officers donā€™t have the time or motivation to go after petty ā€˜crimesā€™ like this, let me remind you - the two FHP cruisers in this stop did over 102 MPH to catch me within 1 minute of me turning my headlights on and off. There are many pro-law websites where LEO really talks nasty about the practice ā€œIā€™d have them arrested for obstruction. The charge wonā€™t stick, but theyā€™ll get a free rideā€ā€¦ or ā€œitā€™s a gift that keeps on givingā€ referencing the insurance rate increase. They take it very personally - that itā€™s disrespectful. They then have a score to settle. One even states with pride ā€œIā€™ve let speeders go to get the punk thatā€™s warning peopleā€ā€¦ fellow posts agree. That being said, in my video, I 'm accused of IMPROPER USE OF HIGH-BEAMS. The trooper refused to listen to my explanation (bogus or not), and insisted I used my brights. When I tried to show the difference in intensity between off/on and on/brights, he got even more offended. The points all of you have made regarding speech issues, I think, are the most legitimate. The statute with which I was cited 316.2397.7 forbids the use of ā€˜flashing lightsā€™ on normal vehicles. Just as in the Kirtland Hills case cited above, the term ā€œflashing lightsā€ refers to a type of light - not the act of ā€œflashing oneā€™s lightsā€. The trooper is trying to prevent others from communicating. Thatā€™s a no-no. Court date has not been assigned yet. I have submitted this to the ACLU under free speech infringement - though Iā€™ve heard nothing back. Also, you may notice that when I asked the Trooper ā€œWhat is illegal with warning other motoristsā€ he did not answer the question. Quick answer: It isnā€™t. Like to hear comments. Thanksā€¦ ---
