What law determines when you have been ordered to pull over for a traffic stop? What laws in the U.S. (specifically, Massachusetts) govern when you need to pull over for a traffic stop? I understand that if a police vehicle comes up behind you with lights flashing it's clear that you have to pull over and stop. But what if a uniformed police officer is standing on the side of the road waving for you to pull over? What about a uniformed officer police just looking at you? Obviously evading or disobeying a police officer when he orders you to pull over is illegal. I'm wondering what constitutes a such an order.
What law in the U.S. governs when you need to pull over for a traffic stop? Specifically, Massachusetts? Refusal to submit to a police officer, Mass. Gen. Laws Ann. ch. 90, § 25 (2016) governs. The relevant part reads: Any person who, while operating or in charge of a motor vehicle . . . who shall refuse or neglect to stop when signalled to stop by any police officer who is in uniform or who displays his badge conspicuously on the outside of his outer coat or garment . . . shall be punished by a fine of one hundred dollars. What about a police standing on the side of the road, waving you over? (perhaps at a speed trap) If the police officer is on a uniform and displays his badge, probably. What about a police just standing on the side of the road, looking at you? Assuming the police officer doesn't "signal" you to stop, you would be okay under this statute. Whether he is legally justified in asking you to stop is a separate issue outside the scope of you question. Bottom Line: Someone who doesn't want to run afoul of this law should stop whenever they think a police officer is pulling them over.
united-states Speed limits can be enforced by any means (except photo-radar) in most U.S. jurisdictions without notice that it is being used. Those laws are close to being uniform in the U.S. due to federal coordination on federally funded roads, even though state and local laws are what governs them directly. Some U.S. jurisdictions prohibit the issuance of photo-radar speeding tickets without notice before entering the photo-radar picture taking zone. I'd have to research further to see if New York City does. The purpose of the language on the sign is to make drivers more fearful of being caught in circumstances where they don't see someone trying to enforce the law, not to have greater legal effect.
There are multiple police forces in the US: city, county, state and national, and each is responsible to a relevant executive. Typical &quot;police&quot; are city police, who are responsible to a chief of police, who is appointed at the municipal level. Counties usually have an elected sheriff, and a set of deputies; at the state level, they are usually called state troopers. The typical protocol is that decisions are made at the lowest applicable level, so Seattle police enforce or refuse to enforce laws within Seattle, and King County police enforce or not in remaining unincorporated locations in the county. Individual city officers do not then decide to ignore the chief of police and instead follow orders from the county sheriff or the governor. However, each state grants vast powers to their governor, so it is possible that in the case of a state of emergency, the governor can take command of all law enforcement in the state. Governors &quot;can't&quot; deploy police to oppose federal law enforcement in a shoot-out, except that they might actually do so on some theory that federal law enforcement officers are violating the law. In general, you are not immune to arrest for illegal acts just because you are a law enforcement officer. The governor of Washington could easily (in the legal sense) declare an emergency and order state troopers to prevent federal officers from effecting arrests. Of course, resolving these disputes in court is another option.
California Vehicle Code Section 21453 (b) regulates right turns on red: Except when a sign is in place prohibiting a turn, a driver, after stopping as required by subdivision (a), facing a steady circular red signal, may turn right, or turn left from a one-way street onto a one-way street. A driver making that turn shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to any vehicle that has approached or is approaching so closely as to constitute an immediate hazard to the driver, and shall continue to yield the right-of-way to that vehicle until the driver can proceed with reasonable safety. No exception is made for intersections where bicycles can go straight, so I conclude that right on red is legal in that case as well. Logically: it is legal to turn right on red from a lane where all traffic must turn right, and it is also legal from a non-turn-only lane where all traffic is allowed to either turn right or go straight. There is no reason for this intermediate case, where some vehicles may go straight and others may not, to be different from the two extremes. Especially since, when the light is red, neither bicycles nor cars nor anything else should be going straight through the intersection.
There is a state law that requires you to obey the police: ORC 2917.13, which says you may not Fail to obey the lawful order of any law enforcement officer engaged in the law enforcement officer's duties at the scene of or in connection with a fire, accident, disaster, riot, or emergency of any kind. If you do, misconduct at an emergency is a misdemeanor of the fourth degree. If a violation of this section creates a risk of physical harm to persons or property, misconduct at an emergency is a misdemeanor of the first degree. You also cannot Hamper the lawful operations of any law enforcement officer, firefighter, rescuer, medical person, emergency medical services person, or other authorized person, engaged in the person's duties at the scene of a fire, accident, disaster, riot, or emergency of any kind "Hamper" is not defined statutorily, but the plain meaning of "hamper" is not the same as "fail to assist". We have not established that the order is lawful, however, which is crucial. The police cannot just freely search a residence without permission. If they have permission from the occupant, they can search and seize. If they have probable cause to believe that a crime exists and the circumstances make a warrant impractical, they can search and seize. I don't know what you mean by "wellness check", but that seems plainly to be unlawful entry. However, if the resident calls 911 and reports that he is having an issue, that is sufficient consent for entry. In the case of a fire alarm, the fire code authorizes a fire department official in charge of an actual emergency response incident to order the evacuation of a building, and occupants are required to comply. If we suppose that the smoke detector in a room has gone off, the fire department is authorized to inspect for fire, and there is a provision under the law about failure to obey a lawful command (to open the door so that they can look for fire). Problem: you cannot know whether the order is lawful. The officer doesn't decide what is lawful, the courts do (after the fact), and typically a command is found to be lawful unless it is clearly unlawful. The order from your supervisor is not "enforceable" in the sense that you cannot be arrested, imprisoned, or fined for disobeying your boss. However, there is a potential club they can use against you, namely firing you for disobeying the order. Normally, you can be fired for wearing the wrong shirt. But there are laws about employers doing illegal things, such as ORC 4113.52, which provides recourse when the employee reasonably believes that the violation is a criminal offense that is likely to cause an imminent risk of physical harm to persons or a hazard to public health or safety etc. In which case you report this to the supervisor, they have 24 hours after getting the report to correct the situation, and after that you would report the situation to the county prosecutor. (Read all of the details in the linked law, don't just skip steps: this is an executive summary). Having done this, you are protected from being fired, demoted. reassigned etc. The employer will be strongly motivated to not incur the penalties for violating the whistle blower statute. Additionally, you can sue the employer if they fire you for refusing to violate the law (termination in violation of public policy).
If you were moving "with the flow of traffic" but over the limit, you were still breaking the law, and the cop can choose which car or cars to stop on any basis or none (except ones forbidden, such as racial in the US). This is almost surely not a valid defense, not in any jurisdiction that I know of at least. If you can show that to slow to the speed limit would have actually been unsafe, you might have a defense, but that is going to be hard to get a court to accept.
Interesting question! I believe all of the examples can be addressed by the following rules: A vehicle on a roadway has the right-of-way over a vehicle not on a roadway. Therefore, the vehicle leaving a parking lot always yields to a vehicle in a parallel road. Absent another rule, the vehicle on the right always has the right-of-way. So if two vehicles are leaving adjacent parking lots, the left one waits for the right one to go if there is any potential conflict. Of course, not enough people know these rules, so in practice if you can't get the vehicle with the legal right-of-way to take it I teach drivers to be as decisive and cautious as possible: I.e., take the right-of-way, but not so fast that you can't avoid the other vehicle if it decides to go after all, because legally you will be at fault in a collision. (Though it's anyone's guess how police and insurers would settle the tricky scenarios you illustrate.)
The ordinance is not very specific about how notice is to be given: therefore, it need not be in writing, and it need not be sent by mail. It would not be surprising if the "notification" came in the form of a city person inspecting the reported obstruction, walking up to the house and knocking and finding nobody home (thus triggering the "In case the owner cannot be found" condition), whereupon the city removes the rocks. That clause does not mean "In case we do not know who the owner is", it almost certainly means "in case the owner cannot be contacted immediately". Article III is in general about obstructions on streets, which are not allowed, except by permit in section 78 under "Permit to Obstruct Traffic Lane". Assuming that no obstruction permit was obtained, what usually happens is that an officer is sent to tell the owner to remove the obstruction (more or less immediately), and if nobody is at the site whom they can tell, they probably won't go any further (e.g. asking neighbors where the owner is). There is no legal definition of "reasonable time", instead the law simply takes that to mean "the amount of time a reasonable person would require". It would thus depend particularly on the size of the obstruction and the volume of traffic. One measure would be how quickly the rocks were moved -- if it was a matter of days and there was no notice, written or otherwise, then there would not be the kind of urgency that might justify the "We knocked and nobody was home" version of notification.
