Question About Traffic Lights

[Frög]

Simple question..

You are stuck at a RED light. What do you do? Do you flash your lights to make it turn GREEN?

If you know the answer, don't ruin this thread.. JUST VOTE!

[qwick]

I wait until it turns green.


I find it funny when someone creeps forward at the red light, like the closer they get to the light the sooner it will change.

dude i do it, some times it works, but it could just be that i do it when its about to change

I wait until it turns green.

i do that all the time! some teacher said the pavement has weight sensors to check if a car is waiting...i dont know though...someone google it

[Ed]

most lights have sensors under the pavement.

Poll is up! VOTE!

shhhhhhhhh!!!! let people vote first!

I know what your talking about, but I was refering to the fokes that almost seem to creep into the intersections while waiting for it to change.

[MrBoostedCRX]

oh i got you...

[HeLLo iM iZzY]

..............

[americanctm]

I don't flash my lights... never heard that actually worked. I pull up on the white line where the weight sensor would be and wait for the light to turn green. Some people wait like 2 car lengths behind the white line (where the sensor is) and it pisses me off.

[hondachik]

I pull up to the line & flash my lights. Either way one has to work dammit.

[C-loS109]

lol at this thread....

i had never heard about the flashing lights...it makes me laugh.

[2003Accord]

I've tried it. seems like sometimes it works and other times it doesnt.

[Jason..]

I beep my horn.

I knew that it was a magnetic sensor, but that technical explanation was cool to read. I don't know much about electricity. There are devices in the market to trip those things that you can put on a low signature vehicle like a motorcycle.

[dabuilding]

most lights have sensors under the pavement.

there are some that are also timed but the ones with the 2 rectangled cuts in the road in front of the stop line are the sensored ones

[bigdare23]

I run it...

[man]

I run it...

Same, IM LIKE A BULL BABY RED MEANS CHARGE THROUGH THAT SHIT lol

It's not a weight sensor, it's a magnetic sensor, this is why a motor scooter can trigger it but a cheerleading squad jumping up and down wouldn't. There are coils under the pavement (look next time, the sensor is shaped like this:

^
||
V

And when the metal body of the vehicle drives over the coil, the natural magnetism of the earth causes a slight current to flow through the coil, which is registered by the light. Creeping forward at a light sometimes CAN help to re-register a current if the light is failing to change when it normally should. There are definitely NO light sensors. Some have no sensors at all and are strictly timing based. Some light6s even have sensors several feet back, or even multiples of ten car lengths back to detect traffic buildups.

Did you not read the last line of the OP...

GOD DAMN IT!

[dimer4life]

I've heard flashing your lights is illegal even though it seems to work most of the time I do it, must be the change of current in the car that the coils underneath the pavement pick up.

[redrumracer]

i let the car roll backwards and then move it forwards.

Try it!

Sorry to ruin your little experiment, I read it but I just kind of.. didn't care. I hate dumb people, so I prevent it by educating. Also, I figured your first post made it obvious that it was dumb.

GOD DAMN IT!

he is only partially right but that depends on where you are because i used to install these so I know the answer................but I will only let the secret out if somebody says please

[blackboi50]

the fuck is this shit!!!????? .....1

for serious??

[tdurr]

shit *****. This is crazy!

[AnthonyF]

I have flashed my lights, but it does not work. I typically roll forward and back.

-Ant.

[Brett]

I yell at it, that seems to make it work to

[toxxxic]

....... what is a traffic light?

[Doppelgänger]

Some cities/intersections have i.r. sensors to detect oncoming emergency vehicles (that have i.r. transponders) to help traffic flow for said emergency vehicles. There was a news article I read where someone attained one of these i.r. transponders for their personal vehicle and proceeded to funk traffic up during rush hour because it was throwing the timing of the lights off. Not all intersections use this technology though. Also, there are measurements in place to keep most of the public from being able to do this by means of different/dual frequency i.r. units.

And as others have said, other lights are either on a strict timer, a magnetic sensor or a combination of both.

[Max_nino]

have yall ever notice the rectangle things are right on the cross walk. I guess people stop right on it and it never triggers the light .

[ztastic]

its after 11 pm u can flash ur lights

[tron]

I yell at it, that seems to make it work to

idk why but this initiated many lolz

[Atlblkz06]

If you think it works - where is the photo sensor?

Lights work on either timing (ugh) or based on a combination of heirarchy and traffic based on pre-set timers and sensor information. You can clearly tell where the sensors are - you'll see rectangular cuts and boxes on the road. The sensors work by detecting a change in inductance in the area above the sensor.

Motorcycles usually have a hard time "tripping" the sensor and often break the law because they're left with no choice lol.

[Frög]

LOL @ the people who voted yes!

[isa2o3]

it only works on some lights. mostly on the ones that are not time based.

[mad3nch1na]

I say "3...2...1... GO!" and it works 99% of the time
