I encourage everyone to use PhotoBlocker Spray and products like it. I have personal experience that faulty cameras can issue uncalled for tickets. I’ll be happy when the red-light cameras disappear permanently from every intersection in North Carolina.
Fair studies show that any gains in safety can be attributed to longer duration yellow lights rather than the cameras. Worse, the entire program is a profit-making venture involving deals between our government and a private contractor that creates incentives to issue more citations than is justifiable.
