Colorado lawmakers rejected a measure to study speeding and red-light cameras to determine whether they should be banned.
A House committee voted 8-5 against advancing the proposal Wednesday.
The proposal sponsored by Democratic House Speaker Mark Ferrandino initially sought to ban the cameras, but it was amended to be a study bill after staunch opposition from law enforcement.
Supporters of traffic cameras argue they reduce accidents. But sponsors of the bill, which included Republicans, say the cameras are used primarily as revenue generators.
The bill had passed the Senate, and it appeared to have a good chance of clearing the House because it was sponsored by Ferrandino, the top-ranking lawmaker of the chamber. But several Democrats voted against his bill.
