When his wife got a speeding ticket, Joe Gadus at first figured she deserved it. But when the retired police officer looked at the stretch of Montgomery County, Texas, road she was ticketed on, he suspected something was wrong. It was. The posted speed limit was 40 mph. It should have been 50 mph. In fact, the Texas Department of Transportation had known for at least 10 months the sign was wrong and hadn't fixed it. Gadus also found out that officers had written between 600 and 1,500 tickets on that stretch of road. Gadus' work got his wife's ticket dismissed.
