If my speedometer breaks without my knowledge, would I be responsible if I broke the speed limit by a small amount? Let's say that I drive down an interstate highway at a speed of 68 miles per hour, where the speed limit is 65. I think that I am going 63 miles per hour because my speedometer is off by five miles per hour - without my knowledge. Would I be responsible for speeding even though I have no reasonable way of knowing that I am breaking the speed limit? Note: I would like to assure everyone that this is entirely hypothetical. I have never encountered anything remotely like this, nor do I expect to.
Yes, you would be responsible. Maintaining the vehicle in a state that enables compliance with the law is the owner's responsibility, and it is a driver's responsibility to comply with the speed limit. There is no knowledge or intent requirement in a speeding violation. That said, a judge might show leniency if you came to court with documentation of a repair or recalibration of the speedometer after the citation.
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.
The reason an at fault driver is liable for damage in a collision is due to the tort of negligence. To be liable under negligence one of the many factors that the plaintiff (that's you in this case) must prove is that the damage you suffered was a reasonably foreseeable consequence of the defendant's (that's the U-turner) acts or omissions. This is where your case would fall down: a collision is a reasonably foreseeable outcome, damage to your braking system in normal operation is not reasonably foreseeable given that an emergency stop is something a breaking system should be able to do. This is simply a maintenance issue.
Can an employer be required to provide an escort from office to vehicle? No, at least, not on the theory articulated in the question. I can imagine some circumstances where it is conceivable that there might be a duty arising from some other source, like an OSHA regulation applied to a firing range business, or an express contract with the employee (some employers provide an escort as a matter of right in the evenings or at other high risk times, as an employee benefit, especially college and university employers, in part, because they have worker's compensation liability while an employee is still on a large campus, in part because it helps attract employees who may feel vulnerable, and in part because of an attitude that the employer wants its employees to be safe at dangerous times of day and this shows that the employer cares about them), or a court injunction related to a labor-management dispute where the employee is a scab. There is no such employer duty, but an employer does have strict liability in almost every case (there are some minor exceptions for very small employers and criminal conduct by an employee who is injured when the criminal conduct is clearly outside the scope of duty of the employee) for injuries and death in the course of employment from any cause whatsoever pretty much (including criminal actions of third-parties) which is generally fully insured by worker's compensation insurance. The exact details of when someone ceases to be at work for worker's compensation/employer liability is buried in case law and regulations (for overtime and minimum wage purposes, the standard is "portal to portal" but workers compensation/employer liability need not be identical, although once you are clearly no longer on the employer's premises and commuting after a day's work is done or before a day's work starts, you are clearly not covered). But, any place where there is employer liability at all, it would be worker's compensation covered. Usually, if the employer is required to have worker's compensation but doesn't, the employer likewise has strict liability for the same harms, but the damages that may be awarded are not limited to those that worker's compensation policies would cover. This leaves the employee with at risk travel between the office and the vehicle. It seems reasonable as well that as the employer prohibits the employees self defence, they would be responsible for the employees defence between office and some safe location (i.e. vehicle). This theory pretty much always loses. An employee walking in an ordinary, non-wartime environment without a firearm is not "at risk" in a meaningful sense, any more than someone who didn't choose to carry a firearm who goes about their daily life (or is prohibited from carrying one due to past conduct such as a felony or a domestic violence protection order or a domestic violence misdemeanor or a condition of parole, probation or bond pending criminal charges). Also, the employee is not being prohibited from engaging in any kind of self-defense or protective action whatsoever (or from asserting self-defense rights if a firearm is carried contrary to an employer rule) just from carrying a firearm at that particular moment (on pain of losing a job, not forfeiting a legal affirmative defense under criminal statutes), which is one of many means by which a person can protect themselves from crimes.
TITLE XXI Section 263:1-a 263:1-a Allowing an Improper Person. – No person shall knowingly permit a motor vehicle owned or controlled by him to be driven by a person who is not properly licensed or otherwise entitled to drive. Any person who violates this section shall be guilty of a violation, and if the license or driving privilege of the person allowed to drive is under suspension or revocation, the owner or person in control of the vehicle, notwithstanding title LXII, shall be fined not less than $100. I would also hazard that allowing someone to use your vehicle knowing they intend to commit a crime would make you an accessory but I don’t think that’s the answer they’re looking for here.
You (probably) did not commit a crime in Colorado. The answer to your question though is probably Driving an unsafe vehicle Colorado Revised Statutes Title 42. Vehicles and Traffic § 42-4-202 (1) It is unlawful for any person to drive...on any highway any vehicle...which is in such unsafe condition as to endanger any person, or which does not contain those parts or is not at all times equipped with such lamps and other equipment in proper condition and adjustment as required in this section and sections... The above is not a crime , it is (5) Any person who violates any provision of this section commits a class A traffic infraction. A class A traffic infraction is a civil violation. Note that some driving offenses are crimes: In Colorado, driving more than 25 mph over the posted limit is a class 2 misdemeanor, and doing so in a constriction zone is a class 1 misdemeanor. Also note that I say probably because it is possible that they charged you with something more extreme- reckless driving? violation of noise or pollution ordinances?- but for a fine small enough that you don't say, 2 points, and you did not have to go to court (you could have if you wanted for the ticket, but not required) it is very unlikely.
40km/h There is no ambiguity. The speed limit on the through road is clear and the speed limit on the side road is irrelevant. The fact that Bob may be legitimately unaware that this is the speed limit doesn’t matter either. If you want to ask if Bob has a defence if issued with an infringement notice, please feel free to post a new question.
Your attorney can file a lawsuit against the other driver, and legal liability can be determined in court. Your want to let an attorney do this, because the one thing that keeps you from being (expensively) counter-sued for defamation is that you didn't name the driver and insurance company. It is extremely unlikely that the other driver accused you of liability ("liable" is a legal conclusion, not a fact). Instead, there is a dispute over the facts. During the trial, both sides get to present their evidence and the judge will determine who is actually liable. If you are found liable, your insurance company may have to pay up. If the other guy is found liable, his company will have to pay up. Or, fault can be split 50-50 (in which case you will be out of luck because you don't have collision insurance to cover your losses). If the insurance company believes that the facts support their client and that you will lose in court, they are not going to volunteer to pay your losses. If they believe that the facts support you, or are closer to 50-50 w.r.t. fault, they are unlikely to volunteer to give you money. If the driver makes a material plainly false statement to his insurance company, they might have recourse against him. Lying under oath is perjury which is a criminal offense. But mis-remembering facts or having incorrect beliefs is not a crime and won't lead to any legal problems for the driver. The belief that you are not at fault is not a lie. If the facts are as cut and dried as you make them out to be, the matter will be easily sorted out in court.
