DES MOINES, Iowa — The House has approved a measure that would put new restrictions on cities that use automated cameras to enforce traffic laws.  

A number of Iowa cities have installed the cameras to cite motorists who run red lights or speed.  

Under the measure approved Wednesday on an 89 to 8 vote, the maximum fine for a red light violation would be $50, roughly half of what most cities charge. The fine for speeders wouldn't change.  

Cities couldn't charge court costs for either type of violation under the measure.  

Backers of the restrictions say the cameras are intended to enhance traffic safety and that cities shouldn't use them as a new source of revenue.  

Tickets issued by using cameras don't count against a driving record.  

The measure now goes to the Senate.
