At a four way stop is it appropriate to wave another driver on even if you arrived at the stop first

Thank you Con for your rebuttal. In the event that something might fall under the accelerator or break pedal it would be best to remove it as soon as possible. I wouldn't bother waving on another person. As it generally wouldn't take me long to clear the obstruction. I realise some people may not possess my dexterity." Your dexterity definitely comes into play when bending down to remove an obstruction but I am not sure if you have ever driven a car with a high seat. In vans and trucks bending over to grab something from under the pedal is an enormous pain. Sometimes, depending on the car (such as my own) the wheel can easily block a person from reaching down quickly and they must maneuver in their seat. Waving someone on before attempting this for than appropriate, especially if no one is behind the person at the stop. I do not consider this point negated as of yet. " The typical offenders of this annoyance don't seem to be struggling to do anything. They are sitting calmly with a smug look waving me on." Again, I can not argue as to why everyone would wave someone on or that they are going so for a good reason. I can only argue that there are good reasons to wave someone else on. "As far as being lost or problems with phone or gps I suggest pulling off the road. There are also drivers behind you, and it is rude to hold them up as well." While I can agree with you that the best course of action is usually to do as you say, depending on the 4-way stop, taking the wrong direction can seriously slow down your estimated time of arrival. When working in the delivery business such as myself, arriving on time can be the difference between a 10 dollar tip and a 2 dollar tip. Sometimes there may not be the option to pullover for another couple blocks. I'd also again like to point of that it is most appropriate to do this when there is no other car behind you. I do not believe that this point has been negated yet either. "The rule is whoever gets to the stop signs first goes first. If everyone follows this rule, than everyone will have a relatively equal amount of time spent at the 4 way." This brings me to another point I'd like to make, that sometimes it can be very hard to tell who arrived first and has the right of way. Sometimes it is appropriate to wave some on because you believe that you are arriving at the same time or that you are arrived after them when you really didn't. Another good instance of this is if I arrive at a 4-way stop at the same time as someone on the opposite lane is also arriving or as just arrived and I forgot to turn my left turn signal on, it is appropriate to wave them to go straight so that you can then take your left turn safely. "When someone breaks traffic rules it creates unsafe situations. It may confuse people. If there are four cars, each at a sign in the four way how clear is it who's being waved on. Following the rules everyone learned when they received their license avoids these situations." While I agree to this, I also would like to add that it is still the driver's responsibility to be observant and yield to any on-coming traffic. At a four-way stop it is quite easy to avoid any accidents if everyone is paying attention and waits until it is safe for them to go. Waving someone on should not cause an accident as long as everyone else is being an observant driver. Part of driving is having to deal with unexpected things, such as pedestrians that break the flow of traffic or worse case scenario, something actually jumping out in front of you. Drivers are, at the end of the day, responsible when they hit some one else so just because someone else waved you on inappropriately and leading to an accident does not make it their fault.
