North Little Rock police are trading in their old black and whites for some new "green" cars.
The department Wednesday rolled out their first cruiser to operate on compressed natural gas. They're the first in the state to use them.
Eventually you'll see nine Tahoes like out on their streets, funded in part by a grant.
But these cars aren't just good for the environment; they'll help your pocketbook too.
Since CNG is much cheaper than regular, the department is expected to save more than $75,000 annually in fuel costs.
"It is going green, so it is a great deal for the police department and we are really excited about it," said Sgt. Brian Dedrick with the North Little Rock Police Department.
The department hopes to replace even more of their fleet with the clean fuel-burners in the future.
