Avoiding a speeding ticket by refusing to tell who the driver was? This hypothetical question is based on a real incident I saw in the news. Suppose that a car is driving over the speed limit by a significant amount, causing a police car to turn around and go after the car. When the police get to the car, it’s parked in a rest stop and all passengers are sitting in the back seat of the car. When the police asks who the driver was, all passengers deny being the driver. What happens in such a situation? Clearly someone was driving the car, but only one of the multiple passengers. Suppose that there is no evidence of who the driver was (no camera footage, for instance). Maybe one of the passengers is the owner of the car, but that doesn’t guarantee that they were the one driving.
In Spain, most traffic offenses are usually considered administrative sanctions and involve just a relatively small fine, and perhaps losing some points in your licence. In those cases, if the driver if the vehicle cannot be established (your example, or a far regular one of a parking violation in which the officer did not see who did park it and will not wait by the side of the parker until the driver appears), the fine just goes to the registered owner. When the fine is reported to the registered owner of the vehicle, he can report who was the actual driver who broke the law at the time of the offense. I do not know what would happen if the person named does not recognize his responsability, but my guess is that the owner has to pay the fine (HINT: do not lend your car to someone who cannot be trusted). If the infraction is so excessive that it becomes a matter of penal law then there must be a trial and then the accused must be established without reasonable doubt, so in that case such a stunt maybe could work.
Hot Pursuit What you're describing is a hot pursuit, and in the US, common law says that police officers crossing state lines while in hot pursuit is absolutely allowed. An active pursuit is considered an exigent circumstance, which gives police all kinds of temporary powers they don't normally have.
The policeman ordered, right as he took a step out of his car &quot;Turn it off!&quot; - which is a lawful demand to prevent the biker from possibly kicking the gas and running. As the driver did not seem to comply (from the policeman's PoV) during his walk over to the bike, he enforced the order himself by turning off the bike and confiscating the key for the moment. Having made it safe that the driver couldn't leg it, he guided traffic around him so he could get to the side of the road. We don't know what happened after the driver reached the curb to be lectured and/or arrested, the bike could be impounded or the confiscation might be temporary. So all we can do here is discuss the action of demanding that a motor vehicle be turned off, the doing of such and taking the keys. Demanding a vehicle to be shut off is standard procedure in police stop, as it is ensuring the safety of everybody involved. In a somewhat recent case (trying to find it again!), a driver did not shut off the car and had to stand on the brake to keep it where it was. As commands came conflicting (keep your hands where we can see them, get out of the car!) and he could not comply or the car would jump forward and ram somewhere, things escalated and the driver was shot. But back to the first step. Was the stop lawful? ACLU in NY tells us: Police may stop and briefly detain you only if there is reasonable suspicion that you committed, are committing, or are about to commit a crime. Don’t bad-mouth a police officer or run away, even if you believe what is happening is unreasonable. That could lead to your arrest. There was a crime committed: Splitting is illegal in NY (among others: Section 1122, overtaking on the right), so the stop was justified under NY CPL 140.50. From my own experience, it is not uncommon for bikers to try to evade police by swerving back into traffic and using their higher mobility to get away. On its face, this makes it reasonable to demand the bike be shut off as the policeman advanced, and I'd like to congratulate the officer for taking the less escalating step and just turning the bike off himself on the noncompliance instead of drawing his gun and possibly escalating it to a use of force. Most lawyers suggest to drivers pulled over to do things akin to &quot;After you brought your car to a complete stop [on the curb], roll down your window and shut off the engine&quot;. Like this one. Possibly confiscating the keys might be an overreach by the policeman, but the demand to turn it off clearly is not.
You give no jurisdiction but in general: First, police have no obligation to be honest. So, yes they can collect this without consent by e.g. taking hair from your hairbrush (with a warrant) or giving you a glass of water while interviewing you and getting it from your fingerprint oils (which may not actually be technically possible but never mind that). No, they can't take it by "force" by sticking a swab in your mouth. Yes, it will almost certainly go into a database. Of course, there are some jurisdictions where police are entitled to decide you are guilty based on the fact that you didn't pay them a bribe.
Assuming, pending information about the jurisdiction, that this happened in the US, the answer is it depends. As described in Justia's Vehicular Searches article and Wikipedia's Motor vehicle exception article, Under US law police can search a motor vehicle without a warrant if they have probable cause. This doctrine was first stated by the US Supreme Court in Carroll v. United States 267 U.S. 132 (1925) and later modified or repeated in Husty v. United States, 282 U.S. 694 (1931); Scher v. United States, 305 U.S. 251 (1938); Brinegar v. United States, 338 U.S. 160 (1949). All of these cases involved contraband, but in Chambers v. Maroney, 399 U.S. 42 (1970), the Court broadened the rule to evidentiary searches. See also Coolidge v. New Hampshire, 403 U.S. 443, 458–64 (1971) In Preston v. United States, 376 U.S. 364 (1964) the Court ruled that the search must be reasonably contemporaneous with the stop, so that it was not permissible to remove the vehicle to the station house for a warrant-less search at the convenience of the police. Subsequent cases have widened the scope of the exception, although the probable cause requirement has remained, and stops must have at least "articulable and reasonable suspicion". In the case of an ordinary traffic stop, the police may conduct a Terry-type search, based on "articulable suspicion". However, if the police arrest the driver, that is grounds to search the car under Atwater v. City of Lago Vista, 532 U.S. 318 (2001) and New York v. Belton, 453 U.S. 454 (1981) Under Michigan v. Thomas, 458 U.S.(and Chambers v. Maroney, 399 U.S. 42 (1970); Texas v. White, 423 U.S. 67 (1975); United States v. Ross, 456 U.S. 798, 807 note 9 (1982).) police may remove the car for a search elsewhere if they have probable cause to believe that there is contraband (such as alcohol, drugs, or weapons) in the car. Thus the arrest justified a search, as described in the question. It might not have justified the tow if there was not probable cause to suspect contraband. But that depends on the detailed facts, and judging those is beyond the scope of this site. In Collins vs Virginia (2018) the Court ruled that a warrant-less search of a car parked on the owner's property and within the curtilage was not justified. (The "curtilage" is the area near the house which gets additional Fourth Amendment protection, almost as if it were inside the house). However, in that case no arrest was made at the time of the search, and the search was based on an officer recalling the car having been used to elude arrest some two months previously, not just a few minutes before, so that case may not apply in the situation described above. If there was no probable cause, any evidence found might be subject to suppression, and a suit for damages under sec 1983 might be brought against the officers and the police force, but that would depend on the specific facts, and would in practice require a lawyer skilled in such matters.
Can anyone help me understand who's liable for any damages that occur? Yes, a judge. Seriously, in almost all cases in a collision between a turning car and a straight traveling cyclist, the car will be held responsible on the basis that the turn should not be commenced unless and until it can be completed safely. If the car has to stop during the turn, the turn shouldn't have been commenced. The only exception would be if evidence could be provided that the cyclist collided deliberately. Does it matter if it's the car that's damaged or the bicycle that's damaged? No
Silence is not cause. However, this may not prevent a search. The officer does not need to tell you that he has probable cause, he must simply have it in order to conduct a search. If he obtained the probable cause before he pulled you over (this is likely), then he will order you out of the car and search over your vociferous (and silent?) objections. If the officer does not have probable cause, searches anyway, and can't come up with a convincing one in time for the court date, then yes you have a claim. But remember, just because the officer didn't inform you of the cause doesn't mean it didn't exist. Always consult an attorney before any legal action.
No. The laws specify what you can and what you cannot do. If the intent of the authority was that you were allowed to drive at 45 mph, you would have a speed limit of 45 mph, not a speed limit of 40 mph. If you go at 41 mph, you are breaking a law and can be punished. That said, law enforcement officers usually have some leeway on how to enforce the law, and they could very well let it pass with just a warning (or even ignore it if they have more pressing issues); the circunstances of it are specific to every situation and officer. The only point that could be made would be if the difference was so small that it could be argued that it can invalidate the evidence on the basis of margin of errors. If the radar catches you driving at 41 mph but the error margin of the radar is 5%, you could argue that you were driving at 39 mph and that the reading is due to the error in the radar1. That would enable you to challenge the evidence (but here the point is not that you are allowed to drive at 41 mph but that there is no proof that you were driving at 41 mph). From what I know, most police forces will be aware of that and avoid issuing fines unless you are well above that margin of error2. 1In fact, in Spain word of the street is that radars are set to account to possible margin of error of the radar, plus possible margin of error of the vehicle speedometer -even if it is the vehicle owner's responsibility to ensure that it works correctly- and some leeway. 2Some people post on the internet the "magic formula" of how many % of speed you can go over the posted speed limit based on those calculations. Of course those magic formulas rely in the radar and the speedometer being 100% accurate and the driver never getting distracted a few seconds and passing it. So, even assuming that those magic formulas are correct, if either the radar or the speedometer are not accurate or the driver gets distracted for a few seconds, you are at risk of getting a ticket.
