Are &quot;safe distance&quot; citations handled on a case-by-case basis? (USA) I've always been told that when you come to a red light or stop sign, to stop far enough behind the car in front of you so that you can see the bottom of their back tires. While a good general rule, I was wondering what would happen if, while you were following this rule, a much larger/speeding vehicle rear-ends you, causing you to hit the car ahead. Would the size/power difference be taken into account as to who's at fault for hitting who? I'm not looking for specific ratios, only if it matters. A bonus would be how much weather is taken into consideration. Currently in CO, but do find myself getting out quite a bit.
There are only two rules I am aware of that apply to rear-end collisions on a roadway (in which all vehicles are properly headed in the same direction): The first vehicle that hits another in the rear is at fault for the collision, and any collateral collisions. The preceding rule is always true unless there is evidence that the vehicle that was struck did something reckless or intentional to cause the collision. For example, "cutting" in front of a truck and decelerating unnecessarily and faster than the truck can brake. (Before dashcams became widespread this was a common tactic of fraudsters, who would subsequently sue the "rear-ender's" insurance company for "whiplash" injuries.) You seem to be asking whether there is a law or rule against coming to a stop too close to a vehicle in front. Tailgating is generally illegal, but I have never heard of the concept being applied to vehicles that are not moving. (Clarification on your question: "Stop far enough behind the car in front of you so that you can see the bottom of their back tires" is a safety heuristic that allows you to pull around the vehicle in an emergency without shifting into reverse. It's a "rule" of defensive driving, but I have never heard it written into law.)
Maybe I'm reading Walsh wrong, but it seems to me to be saying that Stout might apply in some cases, but it doesn't in that specific case. I think you are indeed reading it wrong. In the Walsh case, the court says: We have not had occasion to decide the question up to this time, but now that it is presented, we not only reiterate the doubt which we expressed in the McAlpin case (supra), but we think that the question of the defendant's negligence was erroneously submitted to the jury in the Stout case, and that we ought not to follow it as a precedent. It's clearly repudiating Stout here, and not just as it applies to that case. It literally says they think it should not be followed as precedent.
Until it runs out of gas. With the caveat that I can't prove a negative: No, there is no such statute or case law restricting how long a police or law enforcement vehicle can follow someone on a road. However, law enforcement officers can be subject to investigation and sanction under "stalking" or "harassment" laws, which typically require a pattern of documented misbehavior in the absence of good cause for said behavior.
The principle of constitutional law is that in order to arrest you, the officer would need probable cause. Certain acts are in themselves violations of the order (being closer to another person that 6 feet, illegal sneezing). Walking in public does not per se constitute a violation. In order to briefly stop a person walking on the street (a "Terry stop"), the officer needs a reasonable suspicion that the person is in violation of the law. That means there has to be a reason, and a gut feeling does not count. An officer would not (legally) be able to stop every person they see walking down the street / driving, and demand an explanation of where they are going. If a person is just aimlessly wandering down the strees with friends (even if they are sufficiently separated), that could suffice to justify a stop, given the limited legal excuses for being outside your home.
Here's the relevant statute for Virginia, 46.2-920 A. The driver of any emergency vehicle, when such vehicle is being used in the performance of public services, and when such vehicle is operated under emergency conditions, may, without subjecting himself to criminal prosecution: Disregard speed limits, while having due regard for safety of persons and property; B. The exemptions granted to emergency vehicles by subsection A in subdivisions A1, A3, A4, A5, and A6 shall apply only when the operator of such vehicle displays a flashing, blinking, or alternating emergency light or lights as provided in §§ 46.2-1022 and 46.2-1023 and sounds a siren, exhaust whistle, or air horn designed to give automatically intermittent signals, as may be reasonably necessary. Such exemptions shall not, however, protect the operator of any such vehicle from criminal prosecution for conduct constituting reckless disregard of the safety of persons and property. Nothing in this section shall release the operator of any such vehicle from civil liability for failure to use reasonable care in such operation. So the law does not impose any specific speed limit. Department policy may still impose speed limits on its own officers in this situation, but violating department policy is not a violation of the law per se, if the violation of policy is not reckless. Of course, the million dollar question is what constitutes reckless disregard for the safety of persons and property.
While this question may or may not have a theoretical answer, the practical answer is that you should slow down to 20 mph if there is any chance that the school zone speed limit will be in force at any time that you pass through it. If you do, you will definitely not be cited. If it is at all a close call (say within five minutes of being active), normal differences in time keeping between unsynchronized watches and a lack of any way to prove precisely when you vehicle was where and traveling at what speed, mean that the question of whether the school zone was in effect at the time you were cited will be a question of fact to be resolved based upon the credibility of the witnesses. The witnesses will probably be only the citing officer and you. As a practical matter, you are going to lose the credibility contest on this question of fact 95%+ of the time, and that credibility determination will not be an issue that could be raised on an appeal. Therefore, you should slow down before entering the school zone if it is remotely close to being time for it to be effective to leave a sufficient margin of error against traffic law enforcement officer inaccuracy, which includes any time that the school zone takes effect while you are in it. Even if you could perfectly prove that you were half way through the zone when the speed limit fell from 30 mph to 20 mph, the argument that you needed to break suddenly to comply doesn't cut it. Violating a speed limit is a strict liability offense and you have a duty as a driver to anticipate what you need to do to comply with the law at every stage of your journey. Even if your speed was legal when you entered the zone, you knew or should have known that it was on the verge of being triggered and should have slowed down in advance.
Law enforcement sometimes use "pacing" as a speed enforcement tool. The basic idea is that they consistently drive a certain speed - which is at or above the speed limit and notice that the "alleged speeder" is either keeping pace or exceeding the pace. The details are complicated and a police officer would know them much better than me. But basically They have to calibrate their speedometer - because if their speedometer is broken pacing is obviously worthless. They need to bring the calibration results to court. Not having those calibration records for your speedometer means that many police departments will be reluctant to issue a speeding ticket to the other motorists. They rely on the fact that most state laws allow law enforcement leeway to exceed the posted limit. Not being a lawyer or a police officer, I do not know the exact circumstances, but if they were not allowed to slightly exceed the limit for pacing then logically every pacing enforcement should result in 2 tickets - one being for the officer. If you can swear that your speedometer is good then they can use that evidence to write you a speeding ticket, because whatever allowances the law allows law enforcement for pacing are not granted to you. I am sure they can overcome the calibration issue with regard to a ticket issued to you by your certification that the speedometer is correct. If they issued a ticket to me based on your certification that your speedometer was correct, I would call bullshit. Talking to the police can only hurt you.
First off, the fact that they stopped you on private property is irrelevant. The traffic offense - you driving the vehicle with a suspended license - occurred on public property en route to the station. That offense does not simply disappear because you are now on private property, nor do the police need to wait for you to leave private property in order to stop or arrest you. So... forget the gas station even exists in this scenario. The real issue at hand here is whether or not the officer needs to actually see you driving the vehicle in order to make an arrest. The answer is no. There isn't any other valid reason your car would be where it is now other than it was driven there. If you are the only person with the car, then it's reasonable to assume that you were the one that drove it there. Plenty of people get arrested for this "connect the dots" way of proving they drove, especially in DUI cases. But the officer doesn't even need to assume that second part either. It all comes down to the actual definition of "driving" in the law books. Most citizens would interpret the word as meaning actually moving in a vehicle. That's wrong. Defining a driver and what constitutes driving is actually way, way broader in the eyes of the law. In Kansas, a driver is defined in such a way: 8-1416. "Driver" defined. "Driver" means every person who drives or is in actual physical control of a vehicle. Essentially, having physical control over the vehicle is generally enough to label you as the driver or that you are driving the vehicle. In a lot of states, having possession of the keys to the vehicle is enough for a court to say you had physical control of the vehicle, because "physical control" is more broadly defined as "capable of making it move and within close proximity" to the vehicle. Thus, you can be arrested for traffic-related offenses. It does not matter if the car is parked, if you're filling it with fluids, or just taking a nap in the front seat.
