The CD on the interior mirror, a radar film or hairspray on the license plate. All this should help to ensure that the photo from the speed camera is unclear/invalid. But is that true, what really helps against speed cameras? During the Christmas season, we conducted a survey on Facebook about the tricks our subscribers use to avoid being flashed. The following answers emerged. First the information: NONE of the "tips" should ever actually be implemented / imitated / tried and almost all of them are illegal and therefore punishable. Instead, complying with the maximum speed limit is still the safest option for everyone involvedto avoid unpleasant consequences. And you should even drive "slower than permitted" in danger areas such as hospitals, kindergartens or schools.

a CD on the interior mirror

• Facebook comment by Ronny L.: Hanging CDs on the rear view mirror is very common. This project is said to make the photo unusable due to the reflection. However, the CD would need to be pointing exactly in the direction of the camera during the flash for this to work. How big is the chance? As a rule, the CD dangles around randomly. Another disadvantage is that the CD can also blind the driver and this can lead to accidents. "Back to overview

Various magic letters or foils

• Facebook comment by Hansi W.: There are always advertisements in which there are special foils that should be stuck over the license plate so that the license plate on the photos is illegible. However, masking license plates so that they are unrecognizable is a punishable offense and the foils are absolutely useless. Various tests revealed that individual digits become illegible, but with one photogrammetric evaluation made all digits readable again. If it is found that the effort of the analysis was necessary because of the slide, then you have to dig deep into your pocket. With reflective Anti lightning letters the driver commits a document forgery. From a legal point of view, the license plate is a document. In right-hand traffic, it is used to identify the vehicle. The license plate must unlimited be readable by a radar. So if you stick the reflective foil over your number plate and the number plate is no longer legible, you are falsifying the number plate for the purpose of deception. Tip: There is more on this topic in our article "Flashes anyway: radar slides, anti radar sticker ineffective". "Back to overview

Glue on white cat eyes

• Facebook comment by Sascha S.: You can also glue white cat's eyes around the front of the number plate to get the same effect as a cat's eye counter flash system to have. Simply attach to all four corners and the effect is there. In addition, the costs are kept within limits with this variant. "Back to overview

apply a sun visor strip

• Facebook comment by Oliver R.: In order not to be recognized on bridge measuring systems and stationary systems, you can also stick a sun glare strip on the windshield. If you then also have a football fan pennant and maybe a Mouth-nose protection hanging on the rear view mirror and putting on sunglasses and a hat, then you have a simple cheap protection option. Tip: More information on the exact legal situation with regard to sun visor strips can be found in our article "Tip: sun visor strip allowed? We tell you!". "Back to overview

operate the windshield wiper/washer system

• Facebook comment by Helge N.: If you see a speed camera too late and can no longer initiate a braking manoeuvre, there is still a salvation: the windshield washer system. If the cleaning agent also has a color, with a bit of luck, only a smudged windscreen can be seen in the photo. Tip: In our article "How is a window cleaner used correctly?“Read. "Back to overview

listen to the police radio

• Facebook comment by Mia S.: Another method is to listen to the police radio. This is possible with a mobile radio scanner. Especially when driving overland, the officers like to use the radio. However, since the range of the radio is very limited, the police must be nearby. And with some vehicle radios you can change the country setting, even to the Japan region. Since the frequency band of Japanese radio is shifted slightly downwards, it is possible to receive both our radio stations and the police radio. Tip: You can find out everything you need to know about radio devices in vehicles in our article “Still popular - the CB radio in the vehicle!“Read. "Back to overview

• Here are the steps to convert an old BMW radio:
  - Turn up the radio
  – TP or M for 8 sec. hold down
  – Click on Area Europe with + and –
  – Change to Area Japan with 1 to 6
  – Switch the radio off and on again

quickly apply the brakes or take evasive action

• Facebook comment by Anne R.: Anyone who recognizes the star box at the last moment can, as long as there is no oncoming traffic, switch to the oncoming lane. Since the contact loops usually only reach the middle of the lane, they are used to drive around them. And if no other car is driving directly behind you, then simply brake hard. Two measurements are always made. If the second measurement differs from the first by at least 5%, the result is an incorrect measurement. It is possible that there is still lightning, but a faulty measurement is still a faulty measurement and is therefore not permissible. "Back to overview

grocery bag or rags

• Facebook comment by Bogdan H.: A slightly different trick is it one grocery bag wet and stick it on the license plate. This does not slip due to the wind. If there is an inspection, a bag may have been blown in front of the car. The same thing works with an old rag, by the way. A slightly larger leaf, such as a maple leaf, would be a bit more inconspicuous if you were to be checked. "Back to overview

snowball in winter

• Facebook comment by Ali N.: In winter, the number plate can be made illegible with a well-placed snowball. During an inspection, you can simply state that snow may have been thrown at the car by children unnoticed. And in winter weather you can easily take the number plate with you artificial snow spray. The more you take, the more noticeable it is. But if you check it, you can simply wipe it off again. "Back to overview

dirty mark

• Facebook comment by Jens R.: If you wash the car, you can just leave the license plate dirty. If you have mainly driven on a dirty road, the license plate will be really dirty. Penalties are to be expected here. However, these are cheaper than a fine. "Back to overview

Manipulate license plate holder

• Facebook comment by Lars Z.: On older vehicles that still have a license plate bracket attached to two rods that is built into the bumper, you can simply bend it back far enough so that you can no longer read it from the front. During a control you can say that you parked too far to the curb or in an unknown place where there was an oncoming threat. Alternatively, there are also so-called license plate flippers in various designs (with roller blind, to fold down, with second license plate on it, etc.). Tip: Information on this topic can be found in our article "Illegal! Folding license plate, license plate flipper, license plate roller blind' to read. "Back to overview

folded sun visor

• Facebook comment by Andrea S.: Fold down the sun visor so that you can still see the road well and the shadow is about at the height of your nose. Then pull the collar of the jacket all the way up and a pair of sunglasses on your nose. In the photo you can only be seen from the nose down and the high collar hides any neck features. And then a football fan pennant and maybe one Mouth-nose protection to the rearview mirror. If you have changed your seating position and you happen to look out from under the sun visor, you won't see anything in the photo because you have your sunglasses on. Tip: There is more on the subject of whether larger things are allowed to hang on the interior mirror in our article "Mouth and nose protection on the inside mirror - is that allowed?". "Back to overview

License plate behind the windshield

• Facebook comment by Mike B.: Break the license plate out of its holder and drag it along with the car for a few hundred meters. Damage the clip mount or get a damaged one and mount it on the front. Simply clamp the dented number plate behind the windshield. When there is a check, simply tell them that a truck in front of you lost its load and it hit the license plate. Alternatively, blame it on a rampaging thug or on a rear-end collision the last time you were in a parking lot. Incidentally, the license plate does not necessarily have to be behind the window, just place it in the footwell and not in the windshield. Unless you drive around town all day, the chance of getting caught is pretty slim. If you get caught, they say, screwing on, the bracket is broken. The only thing that can happen is that you Defect report, with license plates screwed on, must be presented to the police within 7 days. You can then remove the number plate and holder again.

Polaroid with polarizing filter

• Facebook comment by Bea P.: Polaroid with a polarization filter allows you to see through reflective front and rear windows. With this, you can immediately recognize technical structures and occupants. This filter technique is also used by speed cameras to take great photos of the driver. Even jostling tank limousines can be recognized immediately. The whole thing not only has a UV filter, but also looks good. Either you have one sent to you directly from Switzerland or you look for a dealer in Germany. You will quickly see the point of metal-coated front lenses in glasses. The polarization filter cannot make it translucent. "Back to overview

Speed ​​cameras do not flash immediately:

• Facebook comment by Ilona H.: As a rule, speed measuring devices are set to a speed that is only around 8 or 9 km/h above the permitted speed limit trigger. For example, you can drive 58 km/h with a speed limit of 50 km/h without being stopped. "Back to overview

Radar detector devices and apps:

• Facebook comment by Hendrik J.: Mobile radar warning devices protect against speed measurement systems. Either as a real radar detector that localizes a speed camera with various sensors. It is available for the interior or as an integration behind the front apron. Counter-flash systems can also be used. There are also mobile phone apps such as Blitzer.de and associated devices such as Ooono, Saphe or even smartphone-independent additional devices. If you want more than 90% protection, it's best to install it EVERYTHING and installs additional software with speed camera warnings on the factory navigation system. Tip: There is more about the various devices, which work in particular via a smartphone connection, in a list under the following video. "Back to overview

• Traffic alarm and warning of speed cameras: the Saphe Drive Mini in the test!
• POI Pilot Connected GPS Hazard Warner with Built-in SIM Card!
• Speed ​​camera apps: what is an offense, what is allowed?

Getting smart beforehand is even allowed

• Facebook comment by Marlene K.: In principle, there is nothing wrong with signing up in the Apron makes smart about the speed cameras. You're even allowed to do that, at least if you don't tap into the police radio. Radio stations and various websites such as Radarfalle.de or Blitzer.de have listed local and national speed cameras. You can also use an app before departure and browse various Facebook pages or WhatsApp/Telegram groups. Another info: New speed cameras are also happy to light up the backside from the vehicle.

black felt-tip pen / white adhesive film

• Facebook comment by Leonhardt F.: A black waterproof one is also a good idea edding. So you can from one Sechs one quick Eight make or one Neuer is becoming Eight. Also can from one P a B will. You can do the same with white adhesive film change the sign."Back to overview

counter flash systems

• Facebook comment by Heike S.: If the driver falls into the speed trap, the reverse flasher emits a bright light that dazzles the cameras. The way it works is based on a principle that is also known to photographers: the flash! Tip: There is more on this topic in our article "Counter flash systems, speed camera jammers & Co.". "Back to overview

laser jammer

• Facebook comment by Paul M.: laser jammer (like from ESO Guard) are devices that warn of laser guns and often prevent detection. The devices are installed inside the vehicle or in the front and usually have a sufficiently high transmission power and warning time so that the speed can be adjusted. And the warning is extremely discreet. Tip: There is more on this topic in our article "Counter flash systems, speed camera jammers & Co.". "Back to overview
