It varies state to state, but usually it's the ol' radar gun. In some places they use police helicopters and radar to check a vehicle's speed. Other states also use plain, unmarked cars to "pace" another car.
no, unless of emergency
You can. Several areas have photo enforcement for speeding, or red lights.
The owner of a car is responsible for the fines (parking, speeding, etc..) except when he provides the name of the driver - or of the person who rented the car. You can choose NOT to pay, and it is likely that there will be no further action. You will not hear of it unless you run across a French police check, in what case the police check into the national police computer will bring the case up.
Check the website of your local police department. Many times, they have listings. Abandoned vehicles are mainly dealt with by the police.
You would have to check the "rap sheets" for various police departments and you still wouldn't know. It would be a public outrage if the stats were made known. Speeding tickets are the bread and butter of most district courts.
Top speed for a Crown Victoria police interceptor is 140MPH. This is not because it is all that the car is capable of, it's because it's governed by the vehicles computer and will stop accelerating once it hits the top speed listed on the speedometer of 140MPH. I sell police vehicles for a living. To check out my credibility look up my company on Google: Martel Autos or Martel's Police Vehicles.
No. In fact I just got a 180$ speeding ticket in Texas and they didn't even check my insurance because it was an out of state vehicle. However, if they ran your insurance when you got pulled over (out of state vehicles sometimes they dont) then it will be reported to your insurance.
Generally speaking, it allows police officers to check the speed of other vehicles in order to enforce traffic laws.
unit numbers. the car is assigned to an officer and they report their number and the car number evrymorning for check ins
There are several variables. It depends on if you were at fault, was there injuries, were there other factors such as speeding or running a light. Points vary from state to state so check with your local Department of Motor Vehicles.
Yes you can. A consequence of over due speeding tickets can sometimes be an arrest warrant. Airlines do not check passengers for warrants. And airport police will only do so if criminal attention is brought to oneself in the airport. Don't yell bomb and you're good to go.
There are no such laws. A police officer can check your speed anywhere along the roadway. If you're in excess of the posted speed for that stretch of road, and they pull you over, it's a ticket.
