It's good to know where the troopers prefer to set-up their speed traps. Learn the tell-tale signs from the driver's seat the most likely sources. In time, by practicing this exercise, it will become second nature to you.
Then your radar detector will be serving its proper role, as an enhancement to your situational awareness, not as its replacement.
Notice this is the same spot the PA State Troopers like to hide as you approach Breezewood, PA at mm 162.9.
If you ever travel this PA Turnpike, be aware this is a favorite sport traveling West-bound towards Pittsburgh, PA.
Also as you develop your situational awareness, its important for you to look far down the road at the vehicles you are following, looking for the tell-tale signs of an approaching speedtrap (even if your radar detector is silent). Sudden brake lights are likely an indicator that something ahead is likely causing them to suddenly brake.
Also look at approaching vehicles, if they flash their headlights that may be another sign that a threat looms ahead of you.
If you are paying close attention then you may learn of the presence of the speed trap before your detectors do.
In this case there was not trooper positioned there, but as evidenced in another video shot here, at another time, he was.
So the moral of the story is develop your situational awareness skills and learn to spot the potential by putting yourself in their shoes (from the comfort of your driver's seat).
By being prepared, you'll be more likely to not create a "safety hazard" by feeling the urgent need to abruptly brake by allowing yourself more time to adjust any potential speeds gradually and safer.
This is a good question, especially if you are a law abiding citizen! Quite simply, to help you be more aware of your driving habits, to stay better alert on long road trips, to be more aware of traffic around you, and to be more aware of road conditions in general. Numerous NHTSA and state studies have shown that the majority of drivers tend to drive at speeds which they feel are both comfortable and safe for the general road conditions -- regardless of the posted speed limit. This is why the government and states saw a sudden drop in accident and highway death rates when speed limits were raised from the national 55 m.p.h. speed limit. What? That doesn't seem to make sense. After all, we have all been told for years that speed kills! When the national speed limit was 55 mph, most drivers ignored it. Yet many conscientious drivers did drive at the 55 mph speed limit. This created large discrepancies in the speeds of vehicles on our highways and interstates, and these speed discrepancies combined with other factors such as improper lane changes contributed to accidents. A U.S. government publication notes that motorists are much safer when all vehicles are traveling at very similar speeds. Lane changes, one of the prevailing causes of highway accidents, are in general much safer to accomplish if all of the surrounding vehicles are traveling at similar speeds.
Seven Reasons Why You Should Use A Radar Detector
First, because radar detectors are a lot of fun to use! A good bit of entertaining driving pleasure, especially on long road trips, can be derived from using a radar detector. It is fun to watch your radar detector detect and alert to radar which is being used by law enforcement. Even your kids will get into the act on long road trips, looking ahead and trying to spot a patrol car before you do. Patrol cars across our nation have a variety of different colors, paint schemes, and different city or state or county logos proudly displayed on them. Some patrol cars actually look quite pretty rather than having just merely functional paint schemes and logos. Your kids might have a lot of fun looking for patrol cars which are their favorite color.
Second, a radar detector can save you from being unfairly singled out for a speeding ticket. Numerous NHTSA and state studies have shown that the majority of drivers tend to drive at speeds which they feel are both safe and comfortable for the given road conditions -- regardless of the posted speed limit. Unfortunately on some roadways the speed limit is set at an unreasonably slower speed. The general public commonly refers to these areas as "speed traps". This is a good example of where a radar detector can save you from receiving a speeding ticket.
Third, a radar detector may actually help you to speed less. After using a radar detector for a few months, you will become much more aware of how active and serious law enforcement really is about patrolling our roadways, and you will naturally tend to drive at slower and safer speeds.
Forth, a radar detector can keep you more alert. Radar detector users report that they generally are much more aware of their driving habits, surrounding traffic, and overall road conditions. This extra "road awareness" is an important safety factor which can help you to avoid being in an accident.
Fifth, a radar detector can warn you of potentially dangerous road conditions due to traffic congestion ahead. Law enforcement, in their effort to make our highways safer, likes to operate radar in areas where both speeding and accidents are common. Thus a radar detector can serve as your advance warning system to alert you about upcoming road conditions or traffic congestion which could make your drive more dangerous. This is particularly useful when traveling through unfamiliar cities and suburbs on long road trips.
Sixth, a radar detector can warn you of an accident scene which is located a mile or more down the road ahead. Many law enforcement agencies teach their officers to leave their radar guns turned on when they are at an accident scene. Your radar detector can give you advance warning that "something is up" regarding the road ahead so that you can be ready to slow down.
Seventh, many municipalities have also implemented the Safety Warning System (SWS). Imagine having your SWS equipped radar detector warn you via a text message that a train is approaching or than an emergency vehicle is approaching. The life which your radar detector could save may well be your own.
So, there you have it! Seven good reasons to use a radar detector. Keep in mind that a radar detector is not going to make you immune from speeding tickets! Contrary to popular belief, this is not the intention of these products. Most of the current radar detector manufacturers do not condone speeding or breaking the law. Unfortunately, many years ago one particular radar detector manufacturer heavily advertised their "No speeding ticket guarantee" in an effort to try to set their products above all the rest. And more recently another company was shut down by the FCC for advertising radar jammer products which, aside from being proven in numerous independent tests to be completely ineffective, are also illegal to manufacture and sell.
There's only so many places that a land-bound enforcer can hide - think like your opponent, let your situational awareness be your front-line driving tool, and not only will you minimize the chances of getting a speeding ticket, but you'll also, first and foremost, become a safer driver overall.

During and after the national 55 speed limmit fiasco I was an EMT and, later, EMS Coordinator. Part of my job was to report accidents and their causes to the state. Both my experiences on the crew and my access to records bore out the truth in the above quote. Our calls on I 90 for one car rollovers and vehicles crossing the medium went through the roof! People were falling asleep at the wheel, or lost concentration due to boredom. Very, very few of them were speeding. After the speed limmits were raised, these types accidents reverted to pre 55 levels. And talking to other ambulance crews and managers statewide, the experience was pretty universal.
Anecdotal, to be sure, but you could infer from this that those who speed (and many did- myself included) were the safer drivers! I do not advocate dangerouse speeds or reckless driving, however, slower is not always safer. One very valid reason to own and know how to use a radar detector!
