Traffic Lights and Signals

Parent Category: Rules of the Road
Traffic lights are devices that allow for alternating flows of traffic. They signal to drivers when it is time to slow down, stop, or go. They help to ease traffic congestion in highly traveled areas.
they didnt have traffic lights back then sorry :/
it was the person of jesus and he loved people and made a stop light invention...
because there were too many accidents
A green light usually last a minute to two minutes.
Analogy indecipherable, since the "cars stopped at a traffic light" are performing no actions. The analogy of cars controlled by a stoplight is often used to describe the impact of control devices on flows in a pipeline where the stoplight acts as a valve periodically releasing a fluid. The...
You may turn in the direction the arrow is indicating. No other maeuvers are allowed.
The national standard for yellow lights is to allow one second for each 10 mph of the posted speed limit. So in a 55 mph posted zone, the yellow light should last at least 5.5 seconds. Recently a number of cities have been busted for shortening the yellow light times and collecting millions of...
1. If you are directed to by a police officer 2. If you are part of a funeral procession 3. If you are part of a parade
There is Red for stop Yellow for slow Green for Go
If you are asking what the height of a traffic light above the street is, that is usually set by the specifications of the individual states or municipalities, and usually designed to be high enough to clear the tallest oad that can be lawfully transported on the highways without special permit.
If you are approaching it and have time to apply your brakes before it turns red, apply your brakes and come to a stop. If it changes as you are too close to it to avoid slamming on youir brakes, for safety's sake pass through it - - but DON'T go through if it's going to turn red as you arrive at...
it means slow down or jail. that's all get it?
The traffic light, as we know it today, actually went through a few phases of invention. 1868 - JP Knight created a signal based on red and green gas lamps. It took an officer to operate it. It exploded about one month later and injured the officer on duty. 1912 - Lester Wire invented the...
%DETAILS%. Answer . Hey Ben==Have the engine tuned up and have the motor and trans supports checked. GoodluckJoe.
Unless the lane is specifically marked as "Right turn permitted without stopping", yes. In any case you would still be required to yield.

It did change the wrold alot because we didnt have traffic lights and there would be alot of accidents and when they invented the traffic light they could get around easier and it made it safer
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...
Well, the first one that was used was in 1912 in Salt Lake City byLester Wire, but the first one permanently installed was probablyone in Cleveland, Ohio, in 1914. It was installed by the AmericanTraffic Signal Company. These first ones only had red and greenlights (like previous ones that used gas...
On December 10, 1868, the first traffic lights were installed outside the British Houses of Parliament in London,
If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.
Yes, it was. The traffic light was first invented and used on December 10 th 1868, this light unlike modern lights was hand operated by a police officer, which made it far less practical than that of the modern light. Eventually in 1912, the first known modern electric traffic light was used, this...
The Red Light Is Telling Everyone To Stop. The Green Arrow Is Telling You It Is Ok To Turn At That Time (Which Ever Way The Light Is Pointing).
It's either EGR or idle control valve. Try cleaning the throttle body and the idle control valve first.
LED light source stability and energy saving
It changed history because it kept people from getting into car crashes
Coils of wire are buried under the road's surface to detect the metal in the car. Next time you are riding in a car look and you can usually see the lines in the asphalt where cuts were made to bury the wires. The signal from the detector is sent to the computer that runs the lights so it knows...
i do not have a clue what your talking about! why not define what you mean?
Most(?) highway departments set their amber caution-light sequence so that there is one second af amber for every 10 mph of posted speed on that road (i.e.: 50 mph posted speed = 5 seconds of amber).
My car is a 1997 Mitsubishi Galant, and when it was idle it used to do the same thing, I was told it might be time to change the TPS Sensor (Throttle Position Sensor). I still need to change it, but what I figured out, is that when you let the car fully warm up, when the needle is as close to the...
