According to the Texas Tranportation Code, 545.156, A police vehicle only need use an audible signal, with no light, or meet the lighting requirements of 547.305 and 547.702.srothstein wrote: AS CHL/LEO pointed out, the law requires you to stop for the vehicle displaying the red and blue (or just red for fire) lights. In most cases, if you signal your intent and pull over at the next safe or lighted place, no one will think badly of you. If you just ignore the car, you will hear the siren and see more cars fairly quickly. You will also get charged with evading (which is a felony) at that point. This may give you a defense since evading does require you to know it is a police officer.
According to 547.702, police vehicles do not have to have red or blue lights. :)
What is illegal about that?Worst of all is the cars I believe to be illegal but growing in popularity - the stealth marked cars with the markings on the side in the same color - but a very slightly different shade - as the car's paint job. I would love to see those explicitly banned since I think they are just for the money.
