Ice-Crusted Stop Sign on a Gravel County Road at Dusk
It is 5:50 p.m. in late November. You are northbound on a snow-packed gravel county road at 45 mph, approaching a paved county road that carries fast traffic. A low sun and road spray have smeared your windshield. About 700 feet back you passed a yellow diamond sign with a black crossroad symbol. At the corner, a sign on your right has its face crusted with ice and snow; you can make out an eight-sided outline mounted about seven feet up on a steel post. Across the intersection a second post shows only the gray back of a sign that faces the cross road. A stand of cedars on your right blocks your view of eastbound traffic until you are nearly at the crossing. A full-size pickup approaching from your left at highway speed has not visibly slowed. Your speedometer reads 45 mph.
1. Can you tell what the ice-covered sign is, and what does it require of you?

Yes. The octagon is used for STOP signs and nothing else, so the shape alone identifies the sign even with the face unreadable, and shape is legally part of a sign's message. The mounting height and the yellow crossroad warning you passed 700 feet back corroborate it.
That means a full stop is required. 'The face was iced over' is not a defense; a driver who can see an eight-sided sign is expected to know what it is and to obey it. The crossroad warning also told you an intersection was coming, so you had advance notice to be slowing already.
There is a second, independent reason to be slow: you are on packed snow and gravel, and your stopping distance is far longer than on dry pavement. You should be able to stop within the distance you can see to be clear, and the cedars plus the low sun cut that distance sharply. Reduce speed now, brake gently and early, and plan to stop short of the intersection rather than in it.
2. You are stopped at the road edge, but the cedars block your view to the right. How do you get a safe look without giving up your stop?

Treat it as a two-stage stop rather than one rolling stop. First stop at the marked stop line if one is visible; if not, stop before the crosswalk or before the edge of the traveled way of the paved road. That first stop satisfies the stop sign.
Then creep forward at walking pace, with the wheels nearly straight, until you can see far enough down the paved road to judge gaps. Because you are pulling downhill or across loose snow onto pavement, allow extra distance and expect limited acceleration. Stop a second time before any part of your vehicle enters the traffic lane and complete your visual scan left, right, and left again.
The failure mode this prevents is the 'look while rolling' habit: rolling forward while your head is turned leaves the front of the car already in the through lane before you have confirmed it is clear. On snow, that is unrecoverable in the time available.
3. The pickup driver flashes his headlights and waves you across. Do you go, and what if the sign had been knocked down entirely?
Read the worked answer
Do not go on the wave alone. Right of way cannot be handed over by a hand gesture or a headlight flash, and the pickup is still closing at highway speed. Drivers routinely wave others through while misjudging closure speed, stopping distance on snow, or a second lane they cannot see past. Accept the gesture only as one piece of information, and only after you have independently confirmed that the gap is large enough for your slow, low-traction start.
If the sign were entirely gone, the intersection would be uncontrolled as far as you can see, and the rule is to yield to traffic already in the intersection and to the vehicle on your right. You should also not assume the drivers on the paved road have a stop sign just because they have a sign post facing them; you cannot read its face from the back. Slow to a crawl, use the two-stage look, and treat the crossing as one where you must yield until proven otherwise.
