traffic stop, do you have to give id if no crime was commited? If you are involved in a traffic stop where the officer can not provide you with a crime you have committed or a ordinance you have broken is the officer allowed (legally) to ask/demand your id? According to RCW 46.61.020, during a traffic stop the driver of the car must provide license, registration and proof of insurance to an officer. And for those who have heard that you can keep your window up and press your ID against the glass, I wouldn’t recommend it. It is unlawful for a driver to refuse an officer’s request to take ID for inspection during a traffic stop.
We need to assume that the stop was legal (not a high hurdle to clear), that is, there was some reason to stop you. Even so, following Utah v. Strieff, police don't actually have to have a reasonable suspicion to stop you and if in the course of an ID check they discover that you have a warrant out for your arrest, the arrest is still legal. So if the police stop you, RCW 46.61.020(1) says: It is unlawful for any person while operating or in charge of any vehicle to refuse when requested by a police officer to give his or her name and address and the name and address of the owner of such vehicle, or for such person to give a false name and address, and it is likewise unlawful for any such person to refuse or neglect to stop when signaled to stop by any police officer or to refuse upon demand of such police officer to produce his or her certificate of license registration of such vehicle, his or her insurance identification card, or his or her vehicle driver's license or to refuse to permit such officer to take any such license, card, or certificate for the purpose of examination thereof or to refuse to permit the examination of any equipment of such vehicle or the weighing of such vehicle or to refuse or neglect to produce the certificate of license registration of such vehicle, insurance card, or his or her vehicle driver's license when requested by any court. Any police officer shall on request produce evidence of his or her authorization as such. There is no law that says "you have to provide ID only if accused of a crime", or "police can pull you over only if you are suspected of a crime". Various traffic infractions will get you pulled over but are not crimes; random sobriety checks are legal. However, note that the requirement to provide ID applies to the operator. There is no law requiring citizens to carry identification papers (but there is a law requiring a vehicle operator to carry a specific form of ID). In some states there are "stop and identify" laws which allow police to demand ID from a person suspected of a crime, but Washington does not have such a law.
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.
united-states In the US, the default rule is that your home is your castle. In general, nobody, not even the police, can enter your home without your permission. The main exception to this rule is that police do not need your permission if they have a search warrant to search your home. To get a warrant, the police must convince a magistrate that they have good reason (ie, &quot;probable cause&quot;), such as a gps track, to believe they will find evidence of a crime if they search the house. The police in your hypothetical are in a similar situation to police who are tracking the gps signal from a &quot;bait car/bike/phone/tablet/package.&quot; (A bait car is a car/etc that has been fitted with a camera and gps tracker, and left out as bait for thieves.) As long as the car is in public view, the police do not need a warrant to search it and arrest the person driving it. However, once the bait car is out of public view, where the police can no longer see it, they need a warrant to go in and recover it, even if they can see it on the tracker. (See, for example, the instructions for bait car programs from the Eugene and Reno Police Departments.) (For phones, which may not be in &quot;plain view&quot; even if the thief is, the police use ring programs to make the phone ring. Hearing a phone respond to a ring program gives them probable cause under the &quot;hearing&quot; version of the &quot;plain view&quot; doctrine.) Bottom line: In the US, the police need a search warrant. Since search warrants take time and effort, police may be unwilling to get a warrant for something as low valued as a phone. If the police can't or won't help, there are various options for privately enforcing one's rights. These range from the legal -- knocking on the door and confronting the thief -- to the illegal -- left to your imagination.
Taking the stated facts at face value (i.e. you can prove them in court). Md. TRANSPORTATION Code Ann. § 20-102 § 20-102. Driver to remain at scene -- Accidents resulting in bodily injury or death (a) Bodily injury. -- (1) The driver of each vehicle involved in an accident that results in bodily injury to another person immediately shall stop the vehicle as close as possible to the scene of the accident, without obstructing traffic more than necessary. (2) The driver of each vehicle involved in an accident that results in bodily injury to another person immediately shall return to and remain at the scene of the accident until the driver has complied with § 20-104 of this title. So, you must stay there until you have complied with § 20-104. Md. TRANSPORTATION Code Ann. § 20-104 § 20-104. Duty to give information and render aid (a) Rendering assistance. -- The driver of each vehicle involved in an accident that results in bodily injury to or death of any person or in damage to an attended vehicle or other attended property shall render reasonable assistance to any person injured in the accident and, if the person requests medical treatment or it is apparent that medical treatment is necessary, arrange for the transportation of the person to a physician, surgeon, or hospital for medical treatment. (b) Duty to give certain information. -- The driver of each vehicle involved in an accident that results in bodily injury to or death of any person or in damage to an attended vehicle or other attended property shall give his name, his address, and the registration number of the vehicle he is driving and, on request, exhibit his license to drive, if it is available, to: (1) Any person injured in the accident; and (2) The driver, occupant of, or person attending any vehicle or other property damaged in the accident. (c) Exhibiting license. -- The driver of each vehicle involved in an accident that results in bodily injury to or death of any person or in damage to an attended vehicle or other attended property shall give the same information described in subsection (b) of this section and, on request, exhibit his license to drive, if it is available, to any police officer who is at the scene of or otherwise is investigating the accident. (d) If no one able to receive information. -- If a police officer is not present and none of the specified persons is in condition to receive the information to which the person otherwise would be entitled under this section, the driver, after fulfilling to the extent possible every other requirement of § 20-102 of this title and subsection (a) of this section, immediately shall report the accident to the nearest office of an authorized police authority and give the information specified in subsection (b) of this section. So, not only is it legal to leave to seek aid, its required.
In Ohio, a stop sign would be a traffic control device, but not a traffic control signal. From R.C. 4511.01: (QQ) &quot;Traffic control device&quot; means a flagger, sign, signal, marking, or other device used to regulate, warn, or guide traffic, placed on, over, or adjacent to a street, highway, private road open to public travel, pedestrian facility, or shared-use path by authority of a public agency or official having jurisdiction, or, in the case of a private road open to public travel, by authority of the private owner or private official having jurisdiction. (RR) &quot;Traffic control signal&quot; means any highway traffic signal by which traffic is alternately directed to stop and permitted to proceed.
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 are not reading a law book here and you should not interpret a driving test so literally. It's quite clear that the question implies you should follow all of their instructions regarding how to proceed through traffic. Sometimes those instructions do involve "breaking laws" such as driving on the wrong side of the road or proceeding through a traffic signal that was not turned off. The B option clearly does not mean they have the power to disobey all laws in existence, only those concerning traffic as evidenced by the examples given. You are not Sheldon Cooper and you should know how to interpret a vague question correctly. You are also not a gopher, and you can correctly deduce that crashing into another car or driving off the cliff into the water is not in your best interests, and that calling the police to report someone abusing their position is probably a good idea. If you're concerned by the wording, try contacting the California DMV to have them clarify the wording.
You are right, the entry and exit photos are only evidence that you were there. This is something they need to prove so the photos may only be for that. Their statement that you didn’t display a valid ticket/permit is, at present an unevidenced assertion. If you contest this, they will provide evidence that you didn’t (e.g. the actual records they refer to) and you would provide evidence that you did and, if it goes to court, the judge will decide what evidence they prefer. As this is not a criminal matter, they need to prove the offence on the balance of probabilities. However, there are almost certainly administrative remedies which will allow you to contest the fine without going to court. This would involve you sending them a copy of the permit and them assessing whether their belief that you didn’t display it is justified or not.
