I was last in Virginia in October 2022, however, that was *northern* Virginia, specifically Chantilly. I haven't been on I-95 or I-81 since pre-pandemic days -- my main reason for traveling that way, a father-in-law who lived in NC and now lives in TN, has not wanted people visiting due to the pandemic, and my wife and I have respected that.
I remember when I lived in Maryland, working with someone coming back from a vacation who had a mandatory court appearance (no arrest or impoundment though) for reckless driving, 81 in a 70 on I-95, and it was a big deal since that sort of thing needs to be reported when you do certain Federal government work (as we did).
*I've never understood why anyone thinks that because the traffic laws in one state say something, the traffic laws in all other states are necessarily the same. This frequently comes up in local discussions about red-light cameras, for example—there's always someone from out West, from a state where they photograph the front of the car, who is adamant that they can't issue you a ticket if there is no picture of the driver. Um, no, the law here expressly requires that the photograph be of the rear of the car only. The thing that puzzles me is how everyone is used to the idea that the single bit of traffic law that most directly affects most people—speed limits—vary from state to state and most people have no trouble with that concept, yet they can't seem to fathom that other aspects of traffic law might also vary. It's not like it's unreasonable for there to be variance for certain things.
I think this is a direct function of reciprocity between states when transferring licenses, and the ease of car travel between states.
I have lived in six different states: NY, MA, NH, back to MA, then VA, MD, and now PA. I got my driver's license in NY in 1996 and my motorcycle license in MA in 2005. In NO case when I moved states, did I have to take any sort of written test or road test on those state's laws when changing over my driver's license. My Pennsylvania driver's license is based on that 1996 car road test (1994 written permit test) in New York and that 2005 motorcycle road test (2004 written permit test) in Massachusetts, having provided PennDOT with a Maryland driver's license also based on those four tests.
In addition to states honoring each other's written and road tests, enough of traffic law HAS to be the same between states to allow a driver's license from any one state or province to be honored in any other state or province. There are even international standards that are agreed upon (traffic lights and STOP signs, for example).
Differences in punishments for breaking traffic laws in different jurisdictions is honestly not something someone needs to know to be able to drive. I couldn't tell you what the fine/punishment is for a speeding ticket here in Pennsylvania because I haven't gotten one. Also, changes in traffic laws don't nullify millions of drivers' licenses until all those drivers are tested on the legal changes. That would be logistically impractical/ridiculous. Major traffic law changes, like the Move Over laws, get public information campaigns, such as advertising and/or traffic stops with warnings only. I only know Virginia's (former) reckless driving laws from living in a neighboring state and seeing a bunch of people I knew get mandatory court appearances or arrests for them -- I wasn't even aware of the reckless driving punishments when I LIVED in Virginia.
People assume the laws are the same between states because, for the most part, they are -- and that is of necessity. In any state, if you exceed the speed limit, you run the risk of getting a ticket -- though the details of those tickets differ between states. In any state, you must stop at a STOP sign or a red light. Et cetera.
Everyone who has lived in MD probably knows that traffic camera tickets there are only issued beginning at 12 MPH over the posted speed limit, and they don't need a photo of the driver. I don't assume that is the same here in PA; I assume it's similar, though. Your post is the first time I've ever heard "they need a photo of the driver" out West. They don't need to identify the driver in MD because it's not a moving violation, it's merely revenue generation -- but it can result in registration suspension if not paid or challenged in court. In order to make it a moving violation, they WOULD need to identify the driver.
