Here you can find your own jammer

Sandra: Recently, my mother forgot to bring her current insurance card into the car, and she is concerned about driving without it. I thought she might not have it, but I was unsure if she would be committing an offense by failing to show it. Is it illegal to operate a vehicle with an expired insurance card?
Currently, police officers request that individuals provide a valid insurance card, which can be shown on a smartphone or as an image of the card. If a parent’s insurance card is no longer valid, numerous law enforcement agencies are linked to the state insurance database, enabling them to swiftly ascertain the validity of a vehicle's insurance. Should the police verify the insurance status through this system, it is unnecessary to issue a citation.
Ty: As radar detectors are legal in Texas, are there any devices that one is not allowed to operate in conjunction with a vehicle's radar detector?
Radar jammers and laser jammer are entirely illegal in the state of Texas. The Texas Traffic Code clearly articulates that no individual is allowed to use, attempt to use, install, or operate a radar jammer in a motor vehicle, except when a law enforcement officer is carrying out their official responsibilities. Consequently, if you own a radar jammer in Texas, it would be prudent to keep it on your bookshelf at home next to your favorite novel. Additionally, the law prohibits the purchase of radar jamming devices, as it states that no person shall buy, sell, or offer such devices for sale. These devices are primarily intended for those who frequently exceed speed limits. It is crucial for drivers to be aware that these signal jammers may not perform as advertised. Compliance with the law would certainly make life easier.
Each day, I offer prayers for the protection of all police officers. I understand that your role is fraught with danger as you strive to safeguard the welfare of all citizens, extending beyond your local area to encompass the entire state of Texas. I face ongoing parking difficulties on my street. While trying to back out of my driveway, I encountered a car parked directly behind it, across the street. I have already addressed parking issues with my neighbor. My intention is not to create problems for anyone by parking incorrectly. What actions should I consider? What violation might this represent?
The issue of parking has been a persistent concern, and it is crucial to address your situation, along with those of others who share similar frustrations. I would like to clarify that your neighbor did not violate any regulations by parking their car on the opposite side of the street, behind your driveway. I recognize the challenges and anxiety that can arise when attempting to exit a driveway, but the law does not mandate any specific parking behavior from drivers. It may be advantageous for you to engage in discussions with your neighbors, kindly requesting that they refrain from parking in that area to prevent any potential damage to their vehicles. Furthermore, please consider that if you were to accidentally strike a parked vehicle while backing up, you could face charges for unsafe backing. Consequently, if you are unable to back up safely, it is prudent to avoid doing so.
