Voters would get to decide whether any governments in Missouri should be able to use red light cameras under a measure moving forward in the Missouri House.
The House on Wednesday gave initial approval to a bill that would a question on the 2016 ballot banning automated traffic enforcement.
Supporters of the ban say red light cameras are used by cities to generate revenue and that there is limited evidence on whether they improve safety.
The measure comes up at a time when legal cases challenging the use of red light cameras in the state are awaiting a decision by the Missouri Supreme Court.
The bill was approved 141-14 and faces another vote before heading to the Senate.
