PROVO -- Utah County's top health official wants police to ticket motorists who leave a trail of black fumes from tailpipes.
The Daily Herald of Provo reports that Dr. Joseph Miner is preparing a battle plan to reduce tailpipe emissions.
Miner also wants to curb unnecessary idling at drive-in restaurants, banks, pharmacies and schools.
Local officials say police don't have time to issue tickets for tailpipe violations. They say the county might have to open its own emission testing facility to enforce the law.
County health officials are raising another problem. They say they are receiving reports that truck operators are tampering with onboard diagnostics to get more horsepower from their rigs, at the cost of dirtier air.
