In an attempt to cut down on air pollution, Vermont lawmakers are considering a bill that would stop trucks from idling in the state, reports the Associated Press.

The Vermont House Natural Resources and Energy Committee are working on a bill that would require trucks that weigh more than 10,000 pounds to not idle for more than five minutes.

However, exemptions will be made for public safety vehicles, trucks delivering oil and other energy products and trucks with cabs designed for drivers to sleep in them.

Those in favor of the bill said Vermont is the only northeastern state without such a law.
