No, you have to move the little lever on the side of the steering wheel.
Seriously, though, there are traffic signals that are on cyclical timers (going on and off in the same pattern endlessly), and others that are connected to sensor loops in the pavement. You can often see where the pavement has been cut with slots at two locations: one at the stopping point, and another at some distance from the intersection (e.g., where the left-turn lane starts).

Traffic signal detectors check for the presence of cars, not their motion. There are two main kinds in use today.
1. Loop detector. These are giant versions of the metal detector you use to find quarters at the beach.
2. Television Detector. These are cameras mounted over the intersection and aimed at the approaches. They can monitor several lanes at a time. Optical recognition is used to recognize shapes.
Note that the signal with detectors changes when the street with the green runs out of cars, or when a preset maximum time expires.
If you are on the street with the red, there is nothing that you can do to make the green come faster. But if you creep up too far, you leave the detection zone, and the light will not change at all.

A right turn is permitted at a red traffic signal only after the driver of the vehicle has?
Stopped!
Can a satellite radio get gps signal?
No. The satellites used to distribute Sirius/XM "satellite" radio operate on frequencies assigned to Sirius/XM "satellite" radio. They don't operate on frequencies allocated to the GPS system.
If your crank sensor goes out how do you know which one to change?
There is only one crank sensor fitted, you may also have a cam sensor. the crank sensor is located either around the bellhousing or around the front crank pulley. It either has 2 or 3 wires. It picks the signal off the revolving crank so look for a sensor in the block near flywheel.
Where is the output speed sensor in a 1995 Jeep Grand Cherokee?
standing at the radiator it is the 2 wire sensor all the way to the right of the transmission case. standing at the radiator it is the 2 wire sensor all the way to the right of the front of the transmission case
Can a pedestrian cross the street against a red light?
Crossing the road without traffic lights may or may not be legal, depending on the local law.A zebra crossing does not count as a traffic light, but is a good place to cross the road.Where traffic lights or zebra crossings are readily available (e.g. within a 100m walking distance) it is advisable to use these designated crossings.On small roads without such designations, it is advised that you cross where vehicles will be able to see you and give way to you safely.In all cases when crossing a road, it is best to check the traffic condition before proceeding.
Should drivers obey cops before a traffic signal?

Difference between sensor and Acatuars?
A sensor is a device that is programmed to send a signal as soon as a specified event occurs; for example the motion sensor in supermarket doors. Meanwhile, an actuator is a device that does an especifc action according to a signal received. Lets go back to the door: Once the motion sensor detects a movements, it send a signal to a piston that moves the door. To sum up: sensors detect events and actuators perform an action
What happens when a crankshaft sensor is defected?
as the crank spins around there is a magnet on it, and the sensor pics up a signal off of it to detect that the crank is in motion. If the sensor fails it will not send a signal to the computor, and that will cause the ignition system to shut down, so you will not have spark.
How does a LED light works in a motion sensor detector?
Two pairs of Infrared LEDs are used as motion sensor detector. The first one is wired to emit LED and the second is wired to transmit a signal when it receives an infrared input. this infrared is reflected back to the receiving LED and then the signal is produced. This signal can be used to open sliding doors, turn on a light or set off an alarm.
What should you do if a traffic signal is red and an officer signals you to stop?
stop... A police officer assuming control of that intersection will have precedence over a traffic signal. If their signals are contrary to the traffic signal, you'll follow their signal.
Other name of traffic signal?
Stop light is another name for a traffic signal.
What is a VW Jetta engine speed sensor?
The engine speed sensor provides the ECM with a crankshaft position signal. The ECM uses the signal to determine a crankshaft reference point (Top Dead Center) and calculate engine speed (RPM.) The signal is also used by the On-Board Diagnostic system for misfire detection. The ignition system will not operate if the ECM does not receive an engine speed sensor input.
A traffic sign which is used to control traffic is called a what?

What are traffic controls?
