Indiana State Police Supt. Paul Whiteshell is telling troopers to enforce the law more aggressively. Whiteshell says there have already been several significant fires parked by discarded smoking materials.
The fine for tossing cigars, cigarettes or matches from a car can be as high as $10,000.
So far this year, Indiana troopers have written about 200 tickets for such offenses, compared to 368 during all of 2011.
