License key Covers

Those license plate covers, sprays, and flashing lamp designed to make your patent plate invisible to red-light cams, speed camera, and toll tags are illegal and pretty obvious. Plus, everything however the more basic plastic covers just don’t work-related anymore.

Overly loud stereo sound system and also PA system

A bumpin stereo device is no illegal to own, however the usage of one can get girlfriend a ticket. Texas allows local federal government to collection noise ordinances. In Austin, it is illegal come “operate sound tools in a automobile audible or resulting in a vibration 30 feet from the equipment”. My interpretation of this is it would be a violation if utilizing a PA mechanism to scream at human being from her car.

Uncovered lights bars

Light bars or any kind of lights that are marketed because that off-road or display use have to be cover when on the road.

Some underglow lights and accessory lights

If the lamp flash, rotate, or oscillate they would be thought about illegal. There can also be no red visible from the front of the car. I recommend continuing to be away indigenous red underglow lamp altogether.

GPS, Radar/Lidar detectors, or Dash cams on the windshield

If the an equipment is placed on her windshield or dash in a method that obscures the motorists view it is considered illegal. The legislation makes no specific mentions of what is consider blocking, therefore it will be approximately the law enforcement officer’s discretion.
