Do you have to stop at a yellow traffic light in MA?
If you can stop within reason, you're expected to, in any state.
What the traffic rules regarding amber traffic lights?
By "amber" I assume you mean yellow. A yellow traffic light indicates that your "right of way" is ending within the next couple seconds. When the light turns yellow you shouldn't enter the intersection if you haven't already, unless you've reached "The point of no return". It's not illegal to go through the intersection while the traffic light is yellow, but if you can stop you should, if you can't stop then go through the intersection (determined by your own judgement). A yellow light is basically a warning of a red light coming, where it is illegal to proceed through the intersection. The duration of a yellow light depends on the road the traffic light is governing. For a side road the traffic light may only show a yellow for around 3 seconds, for a major road such as a state road or US Highway, the traffic light may show a yellow for 4-6 seconds. These timings all depend on the road that the traffic light is governing and what the speed limit is for that road.
Should I get a ticket for being in a intersection because I went on a left yellow arrow and the light turned red before I was able to clear the intersection because of traffic?
General rules of the road state that you must clear the intersection by the time the red light illuminates; if there was traffic preventing you from clearing the intersection before you entered it on a yellow light then you should not have entered the intersection because of impediments to traffic.
Is there a legal length of time for a yellow light?
In the United States, traffic lights are in the category of "traffic control devices" (which also includes signs, pavement markings, etc). There is a US Federal Manual on Uniform Traffic Control Devices (MUTCD) which all states are supposed to follow so that traffic signs and signals are pretty much the same from state to state. The MUTCD contains formulas for calculating the duration of the yellow (sometimes called "amber") traffic light phase to minimize the frequency of collisions near, at, and in intersections. Factors include traffic speed approaching the light and speed of cross traffic, and seeing distance to the light (curves/hills, etc.). The yellow-light interval is supposed to be between 3 and 6 seconds.However, adherence to the MUTCD is not rigorously enforced, and yellow light durations are sometimes set with goals other than minimizing collisions. It is well demonstrated that a relatively long yellow light drops red-light running to nearly zero, which is good for safety but bad for revenue from red-light ticket cameras; companies contracted to run red-light camera programs have often been caught colluding with the municipal or state agency in charge of the lights to shorten the yellow light time. This creates a "dilemma zone" where a non-speeding driver must choose between stopping short for a sudden red light after a quick yellow (and risk being rear-ended, with more money for the insurance company) or going through the suddenly-red light (and getting a ticket, with more money for the red-light camera operator and the city). Such is the influence of the red-light camera industry that the MUTCD protocols for yellow-light duration have been weakened to produce generally shorter yellows despite today's higher traffic speed and density. There is more information in the article(s) linked below.
On a traffic light which position is the green light?
On a vertical display traffic signal the green light is on the bottom. On a horizontal display traffic signal it is to the right, but may depend on that state (or municipality's) practice.

Where in Houston can one find a traffic lawyer?

Is there a ladder logic program for a 4 junction traffic light?
Yes, a ladder logic program for a 4-junction traffic light can be designed using timers and relays to control the lights at each junction. The program typically includes states for each traffic light (e.g., red, yellow, green) and logic to ensure safe transitions between them. Timers can be used to manage the duration of each light state, while interlocks prevent conflicting signals at adjacent junctions. This ensures smooth and safe traffic flow at the intersection.
What are basic principle of working of decorders in traffic light controller?
Decoders in traffic light controllers convert binary inputs from sensors or timers into specific output signals that control the traffic lights. Each binary input corresponds to a particular state of the traffic light (e.g., red, yellow, green) based on predetermined logic. The decoder activates the appropriate outputs to ensure that only one signal is illuminated at a time, following the traffic rules and ensuring safety. This systematic approach allows for efficient and safe management of traffic flow at intersections.
