If your state’s laws refer to a “maximum” speed limit, it is most likely “absolute,” so that it is illegal to exceed it by even 1 mph, period.
If your state’s laws refer to a speed limit above which it is “unlawful to exceed,” or your state’s law says something like “no person shall drive in excess” of that posted or set speed limit, that speed limit is “absolute.”
If the law sets speed limits but then just says it’s “lawful”—in the absence of a hazard—to drive below the speed limit, without flatly saying it’s illegal to exceed that limit, the speed limit is probably “presumed.”
If the law says it’s merely “prima facie unlawful” to exceed the posted speed limit, without reference to “maximum” limits, and it doesn’t flatly forbid driving at a speed over the limit, the speed limit is likely “presumed.”

三种SpeedLimits
50个州基本上使用三种类型的速度限制。我们将这些称为“绝对的”,“假定的”(或法律上的“初步证据”)和“基本”速度限制。由于每种类型的速度限制违规通常都需要独特的防御,因此了解您违反规定的关键是关键。
绝对。大多数州都有“绝对”速度法。这是如何工作的诀窍:如果标志说40英里/小时,你驾驶41英里每小时或更多,你违反了法律。
假定。 “假定的”速度限制违规行为稍微复杂一些,但在建立防御方面给你更大的灵活性。例如,在所有或部分道路上使用该系统的州 - 例如加利福尼亚州和德克萨斯州 - 只要您安全驾驶,驾驶超过限制的道路是合法的。例如,如果您在40英里/小时的区域内行驶50英里/小时,则“假定”是超速行驶。但如果是在清晨干燥的早晨早上6点,在宽阔直道上没有其他车辆,你可以说服法官说你在这些条件下安全驾驶,你应该被无罪释放。那是因为你提出了“反驳推定”的事实,超过了你以不安全的速度驾驶的限制。 (我们将在下面为您提供更多相关信息。)

另,有一个app,名字忘记叫什么了,有点像google map,特点是有人在驾车行驶过程中看到cop了,可以点击一下,做个标示,用同样app的人在经过的时候可以提前在app上看到标示,就知道这里有cop,要小心驾驶。
再另,在米帝还没见到过标示为公里的车。都是英里表。最多也就是英里、公里同时显示。大部分老美还是不知道1英里=1.6公里的。
