What does the blinking red traffic light means in the state of Virginia?
In Virginia, a blinking red traffic light means that drivers must come to a complete stop and yield the right-of-way to any vehicles or pedestrians in the intersection before proceeding. It is treated similarly to a stop sign. Drivers should only continue through the intersection when it is safe to do so.
What is a simple traffic light circuit?
There are many ways you can design a simple traffic light circuit.
I recommend you to use a 4017 IC.
Please check this site as reference. It's a two way traffic light circuit.

On a traffic light in which position is the green light?
Lights are situated as red, yellow, green. In complicated traffic patterns, lights can be arrows, or the /do not/ indicators. When a traffic light is non-functioning at an intersection, the first to the right has right of way, and each driver from each of the 4 sides takes a turn in that order.
The first known traffic signal appeared in London in 1868 near the Houses of Parliament. Designed by JP Knight, it featured two semaphore arms and two gas lamps.
The earliest electric traffic lights include Lester Wire's two-color version set up in Salt Lake City circa 1912, James Hoge's system (US patent #1,251,666) installed in Cleveland by the American Traffic Signal Company in 1914, and William Potts' 4-way red-yellow-green lights introduced in Detroit beginning in 1920.
New York City traffic towers began flashing three-color signals also in 1920.
If you are saying that the engine quits or dies, then it may be the IAC (Idle Air Control) valve needs to be replaced.
Who was the first black man who made the traffic light?
In 1923, Garrett Augustus Morgan, Sr., an African American inventor, patented his own version of the traffic signal. The Morgan traffic signal was a non-electric, T-shaped pole unit that featured three hand-cranked positions: Stop, in all -directional stop position. This third position halted traffic in all directions to allow pedestrians to cross streets more safely. It was never practical enough to put into production. The story nevertheless has been widely and erroneously circulated that Morgan was the "inventor" of the traffic signal.
What makes the traffic light so important?
Traffic lights are important because they regulate traffic safely and make movement of traffic smoother and faster at intersections.
What is the 'Point of No Return' in regards to a traffic light?
If you are approaching the intersection at speed limit, and the traffic light changes to amber/yellow at 100 feet or less, that's the point of no return. Slamming the brakes will cause you to stop at or near the cross traffic.
The state law will probably say a 'safe distance' one rule I've always used, (and it's a good one), is stay back far enough that you can clearly see their back tires where they touch the ground. This will usually provide enough distance. You could check your local rules of the road to see if this addressed in there, other than the 'safe distance'....
You might have a broken or worn transmission/engine mount.
No. This is referred to as "chain of causation". Meaning an accident was created by the another vehicle that was involved. Accident investigators begin with the last vehicle involved or that was last in motion as best they can decern. They progress from that point on to the final results of the accident and then make an evaluation as to responsibility. In this instance all drivers waiting at the light would not be at fault.
How much does car insurance raise after a red traffic light violation?
Each insurance company has their own policy, therefore you would need to check with that particular company. Was there an accident? What state did the violation occur? Do you have a license for that state?
Could the fuel filter be the problem if your car has a rough idle when stopped at a traffic light?
Yes it could. Why not replace it? It's cheap and most people never do until they stall some dark lonely night.
It depends on what kind of car and what engine you have. Go ahead and replace the fuel filter although I don't think it will cure the rough idle. If you have a carburetor, it may need cleaning or adjusting. If you have fuel injection, try some injector cleaner in the tank.
If it's automatic, check the fluid. Low fluid will do that.
I had a similar problem, the car was very slow to start moving. The cause was the transmission range switch was loose and out of adjustment. Another way to tell if this is the problem is to turn the ignition switch on and put it in reverse. If the back up lights do not come on and the bulbs are good, then this could be your problem also. Hope that helps!
How were the colors of the traffic lights were decided upon?
the 3 traffic colors red, green, and yellow were used by trains. So when cars needed similar signals, the colors were copied
If I was you I'd wait behind the white line so that you're out of the intersection. It's unlawful to block an intersection but it's not unlawful to block a driveway of any kind.
What does the road sign mean that has a red triangle with an exclamation point in the middle?
That would be a warning of danger ahead.
What are the positive and negative effects of the traffic light?
Positive - they keep traffic moving.
Negative - they are always red when you approach them
If the flashing lights were on then you violated the law. If they got your license number you will get a ticket. If not then you are safe. In the future when you see a school bus prepare to stop at any moment.
