To simply pull you over, you have to have committed some traffic violation or he/she has to have some articulable reason, such as, you match the description of someone they are looking for, or you have done something suspicious. (example: driving with your wipers on when it's not raining. It's not illegal, but it's suspicious because it's a possible sign of drunk driving).
In many jurisdictions, police enter most plates they stop in front of through the data base, but unless you have a warrant on the vehicle, they still need probable cause to pull you over. Better answer is it depends. A Police Officer has discretion and may or may not run your plate. You may have a warrant on the vehicle or a invalid driving status. Those two reasons are enough to stop the vehicle. Furthermore, Probable Cause is not necessary to stop a vehicle. The level needed is Articulable Suspicion and is a lower degree of certainty than Probable Cause.
Yes, a police officer can pull over multiple vehicles at once.
A cop can always pull you over at any time.
A citizen can not pull over a police officer for bending the law, but you can report them to the superiors of their Police Department.
Yes.
They don't need 'probable cause', just a 'reasonable suspicion'.
Yes, a cop may pull you over on private property in Nevada. There are not any laws that prohibit this.
Yes. But police aren't required to have probable cause to pull you over - the standard is reasonable suspicion, which is much lower than probable cause.
Only if they don't have probable cause.
Difficult and expensive to prove lack of probable cause. Probable cause can be anything from suspicious activity in the vehicle to weaving while driving or failure to signal. I am sure you could find a lawyer who would try but I am also sure the judge would eventually find for probable cause in the end.
Technically, no. However, the definition of "probable cause" can cover a very large area, including the officer making a judgment call as to the way the person's driving, a loose license plate or one that is too dirty to be clearly seen, and so on and so forth.
Yes, If the driver is being distracted especially in the event of a dispute. An officer can pull you over because it could be a kidnapping.
Your previous driving record alone is not probably cause to be pulled over. If you were driving recklessly or in violation of the law, you could be pulled over.
There would exist probable cause to pull you over if the officer had seen you driving without your lights on even if you turned them on after you saw the police car and before you were pulled over.
Yes. Probable cause is anything the police officer wants it to be. A suspicious movement in the car, a possible seat belt violation or even a licence plate light flickering.
Not usually. There is the issue of probable cause (to pull you over). In certain places like Indian reservations and government installations, you can be stopped without cause. You can also be stopped at a checkpoint on a public roadway without cause.
Yes, they can; it's called probable cause and/or reasonable suspicion.
