Just don't get caught with one in Virginia or Florida. They can take your car, though they usually don't, because you generate revenue for the departments. Yes the newer radar guns are expensive, but a few tickets will pay for it. With Laser the only way a detector can pick it up is if he "shoots" someone else. Laser is not a constant emitting unit, but rather a point and shoot. Any radar I have seen cannot read same direction traffic, ie the cop is following you. He's pacing you. Remember cop cars have calibrated speedometers, so if they set a certain distance behind you and just follow you you're screwed. Laser can be used in same direction traffic. Also most states have a certain mph that they allow your speedometer to be "off". In Michigan it is 3mph, but North Carolina has a basic speed limit law, meaning that technically they can pull you for 1mph over.
Things to remember, be curtious (no matter how pissed you are), don't get out and approach the cop as he/she may shoot you. They are running your tag not only to get your info, but to see if the car is stolen, or registered to a known criminal, as we call it a "wants and warrants check". Leave your seatbelt on, even if your getting your wallet out. Just wait until the officer asks you for your DL, Reg, and Proof of Ins. If you're not wearing your seatbelt don't try to put it on, as we have probably already noticed, unless you have really dark windows. Don't make excuses, as we have heard most all of them. If you have a real reason, explain it calmly, don't cuss and don't get excited we will listen when we are ready. If you or your pasenger has a medical emergency then tell the officer. And most of all don't mess with us K-9 guys, as most would really rather like to release our dog than shoot anyone.
Oh yeah if a cop is behind you, and you aren't speeding, DON"T SLOW DOWN!! It kind of erks us. We may be on our way to the DONUT SHOP (I had to get it in before you guys start in on it)
Or the best way to avoid one is DON"T SPEED!! Later.
