Do all camera traffic lights have a flash?

I came up to this red light around 9/930 PM and I was literally the only car stopped at the light. I wanted to make a left but the light didn't turn green for me at all. I waited like 5 to 7 minutes and just treated the light like a stop sign. So after I ran it my friend then tells me there was a camera! But i saw no flash...I know it was dumb, but do you think I am okay or am I going to get fined?Do all camera traffic lights have a flash?
I hate that. I used to drive a truck locally in town, and it was so frustrating when the light would go through two cycles and the turn light would never come on. I've run them before at night, otherwise I'd be sitting there 'til morning. I don't know about the camera, we were lucky here that they took the stupid things down.
They don't have flashes, but you should be okay. The camera's work with night vision so it's more of a video camera than a picture camera . You probably weren't a big deal to the authority's so unless they're really bored it wont matter. Next time try scooting up and braking a little to hit the sensor. During late hours certain lights work on a sensor bases the same system which controls the pedestrian lights. The sensor works like the automatic doors at stores. If they don't detect a car there the lights wont change. Do you remember jumping up and down in front of the sensors as a kid to get the doors to open? That's sort of what you have to do with your car. Move it forward to get on the sensors radar. Good luck!Do all camera traffic lights have a flash?
I'd go with no. I think you'll be ok. No they don't all have flashes. At least I've never been flashed in Chicago.
haha i totally kno how you feel ive been throught that but you have nothing to worry about unless it has that lil flash it dosent have a camera and even thow half the time thers nobody monitoring them ive ran plenty of light lol and h avent got one ticketDo all camera traffic lights have a flash?
I would assume no. Due to safety reasons. The flash can temporary blind or distract the motorist. However, depending of the site it might be well lit for the camera. Some cams are pretty sensitive to light so that determines the amount of illumination is need it.
No.



Traffic lights for vehicles or pedestrians normally have two main lights鈥攁 red light that means 'stop' and a green (or sometimes white for pedestrians) light that means 'go' (or, more correctly, 'proceed with caution'); the use of these colors are thought to originate from nautical right-of-way[citation needed]. Usually, the red light contains some orange in its hue, and the green light contains some blue, to provide some support for people with red-green color blindness. In most countries there is also a yellow (colloquial term) or amber(official term) light, which when on by itself and not flashing means stop if able to do so safely. In some systems, a flashing amber means that a motorist may go ahead with care if the road is clear, giving way to pedestrians and to other road vehicles that may have priority. A flashing red is treated as a regular stop sign.

There may be additional lights (usually a green arrow or "filter") to authorize turns. In the U.S., a turn permitted by such a light is called a protected left or protected right. A left turn light preceding the opposing through movement is called a leading left turn because it leads the opposing through green light (likewise, a left turn arrow that follows the opposing through movement is known as a lagging left turn). In Canada, a turn that is authorized before the opposing traffic is called an advanced green and a green arrow at the end of the phase is called a delayed green. A leading left turn, advanced green, lagging left, or delayed green can apply either to only one direction, allowing both turning and through traffic while opposing traffic is stopped, or to both directions, allowing left turns from opposing directions while all through traffic is stopped.

Traffic lights for special vehicles (such as buses or trams) may use other systems, such as vertical vs. horizontal bars of white light.

4-state lights warn traffic that it will shortly be free to move.In most countries, the sequence is red (stop), green (go), amber (prepare to stop). In the UK [1], New Zealand [2] and Canada [3], amber officially means 'stop' (unless it would cause an accident to do so) but in practice, is treated as 'prepare to stop'. In the UK, Hong Kong, Macau, Pakistan, Germany, Czech Republic, Poland, Denmark, Iceland and Israel, among others, the sequence includes red and amber together before green, which helps draw attention to the impending change to green, to allow drivers to prepare to move off. (In many of these jurisdictions, such as the UK, it is customary for drivers to select neutral and/or use the handbrake at red lights; the additional phase gives the driver time to select first gear or release the handbrake before the light turns green). The single flashing amber signal is used in the UK and Australia at Pelican crossings. Some older signals in New England, mainly near Boston, use the red + amber phase to signify an all-pedestrian phase [4] ("Barnes dance"). These were installed before pedestrian signals came to the area, and before the national standard prohibited them.

Turning signals and rules

In some instances, traffic may turn after stopping on a red (right in right-driving countries; left in left-driving countries), provided they yield to the pedestrians and other vehicles. In some cases which generally disallow this, a sign next to the traffic light indicates that it is allowed at a particular intersection. Conversely, jurisdictions which generally allow this might forbid it at a particular intersection with a "no turn on red" sign, or might put a green arrow to indicate specifically when a right turn is allowed without having to yield to pedestrians (this is usually when traffic from the perpendicular street is making a left turn onto one's street and thus no pedestrians are allowed in the intersection anyway). Some jurisdictions allow turning on red in the opposite direction (left in right-driving countries; right in left-driving countries) from a one-way road onto another one-way road; some of these even allow these turns from a two-way road onto a one-way road. Also differing is whether a red arrow prohibits turns; some jurisdictions require a "no turn on red" sign in these cases. A study in the State of Illinois concluded that allowing drivers to proceed straight on red after stopping, at specially posted T-intersections where the intersecting road went only left, was dangerous. Proceeding straight on red at T-intersections where the intersecting road went only left was once legal in Mainland China with right-hand traffic provided that such movement would not interfere with other traffic, but when the Road Traffic Safety Law of the People's Republic of China took effect on 1 May 2004, such movement was outlawed.

In Ireland, France, Spain, and Romania permission to turn right (or more rarely to turn left or to go straight on) on a red light is indicated by a flashing amber arrow (cars do not have to stop but must yield way to other cars and pedestrians). In New Zealand, turning on a red light is forbidden. However dedicated signals for turning are usually used for the same effect.

Another distinction is between intersections that have dedicated signals for turning across the flow of opposing traffic and those that do not. Such signals are called dedicated left-turn lights in the United States and Canada (since opposing traffic is on the left). With dedicated left turn signals, a left-pointing arrow turns green when traffic may turn left without conflict, and turns red or disappears otherwise. Such a signal is referred to as a "protected" signal if it has its own red phase; a "permissive" signal does not have such a feature. Three standard versions of the permissive signal exist: One version is a horizontal bar with five lights - the green and yellow arrows are located between the standard green and yellow lights. A vertical 5-light bar holds the arrows underneath the standard green light (in this arrangement, the yellow arrow is sometimes omitted, leaving only the green arrow below the solid green light, or possibly an LED based device capable of showing both green and yellow arrows within a single lamp housing). A third type is known as a "doghouse" or "cluster head" - a vertical column with the two normal lights is on the right hand side of the signal, a vertical column with the two arrows is located on the left, and the normal red signal is in the middle above the two columns. In a fourth type, sometimes seen at intersections in Ontario and Quebec, Canada, there is no dedicated left-turn lamp per se. Instead, the normal green lamp flashes rapidly, indicating permission to go straight as well as make a left turn in front of opposing traffic, which is being held by a steady red lamp. (This "flashing green" can be somewhat startling and confusing to drivers not familiar with this system.) Another interesting practice seen at least in Ontario is that cars wishing to turn left that arrived after the left turn signal ended can do so during the amber phase, as long as there is enough time to make a safe turn.

Generally, a dedicated left-turn signal is illuminated at the beginning of the green phase of the green-yellow-red-green cycle. This allows left-turn traffic, which often consists of just a few cars, to vacate the intersection quickly before giving priority to vehicles travelling straight. This increases the throughput of left-turn traffic while reducing the number of drivers, perhaps frustrated by long waits in heavy traffic for opposing traffic to clear, attempting to make an illegal left turn on red. If there is no left-turn signal, the law requires one to yield to oncoming traffic and turn when the intersection is clear and it is safe to do so. Nevertheless, it is increasingly and disturbingly common in at least the U.S. to see drivers who do not yield in the absence of a dedicated signal, cutting off traffic that has right-of-way and is starting to head across the intersection. In the U.S., many older inner-city and rural areas do not have dedicated left-turn lights, while most newer suburban areas have them. Such lights tend to decrease the overall efficiency of the intersection as it becomes congested, although it makes intersections safer by reducing the risk of head-on collisions and may even speed up through traffic, but if a significant amount of traffic is turning, a dedicated turn signal helps eliminate congestion.

Pedestrian crossing light with loudspeaker for the blind.Intersections with dedicated protected signals occasionally have what is known as "yellow trap", "lag-trap", or "left turn trap" (in right-driving countries). It occurs when vehicles are permitted to make left turns on normal green lights, or when one direction has a dedicated turn signal and the other direction doesn't.

For example, an intersection has dedicated left-turn signals for traffic travelling north, but not south. The southbound traffic gets a red light so northbound traffic can make a left turn, but the straight northbound traffic continues to get a green light. A southbound driver who had entered the intersection earlier will now be in a predicament, since they have no idea whether straight traffic for both directions is becoming red, or just their direction. The driver will now have to check the traffic light behind them, which is often impossible from the viewing angle of a driver's seat. This can also happen when emergency vehicles or railroads pre-empt normal signal operation.

Although motorcycles and scooters in most jurisdictions follow the same traffic signal rules for left turns as do cars and trucks, some places, such as Taiwan, have different rules. In these areas, it is not permitted for such small and often hard-to-see vehicles to turn left in front of oncoming traffic on certain high-volume roads when there is no dedicated left-turn signal. Instead, in order to make a left turn, the rider moves to the right side of the road, travels through the first half of the intersection on green, then slows down and stops directly in front of the line of cars on the driver's right waiting to travel across the intersection, which are of course being held by a red light. There is often a white box painted on the road in this location to indicate where the riders should group. The rider turns the bike 90 degrees to the left from the original direction of travel and proceeds along with the line of cars when the red light turns green, completing the left turn. This procedure improves safety because the rider never has to cross oncoming traffic, which is particularly important given the much greater likelihood of injury when a cycle is hit by a car or truck.

In the UK: traffic can proceed on a full green (whole signal disc is green) if safe to do so, but traffic turning right may be in conflict with traffic coming in the opposite direction. Traffic lights only applicable to traffic going a certain direction are called "indicative green arrows" and are shown as a green arrow pointing in the direction that traffic is allowed to proceed. It is illegal to turn in any other direction unless there is also a full green signal. These signals imply that it is safe to proceed in the indicated direction as there will be no conflicting traffic flow. This is commonly used at junctions where traffic needs to turn right across the junction where there is no oncoming traffic. A filter green light is a green arrow signal displayed together with a red signal, and indicates that vehicles may proceed in that direction (only) and that all other traffic must stop. A filter is often used to permit a left turn during a period in the signaling cycle when it is safe to do so, but can be used for other purposes.

Some jurisdictions (e.g. Switzerland, France, Austria and some states of Australia), however, have additional right-of-way signs mounted above the traffic lights (below in Australia); these take effect when the lights are no longer active. In the UK, drivers simply treat the junction as being uncontrolled when traffic lights fail, giving way as appropriate, unless a police officer is present. In 1999, concerned that some traffic lights would fail as a result of the Y2K bug, some jurisdictions installed emergency unfoldable stop signs at intersections[citation needed].

In some countries, pedestrian traffic lights include a type of siren or warbler, which sounds during the red phase, in order to alert visually impaired pedestrians that it is safe to cross. These are generally set to a timer and only sound at day time, to avoid annoying residents. In the UK a "beeping" sounder indicates a green light. Some other intersections include a white strobe light mounted inside the red light that flashes every few seconds when the light is red.
