A Massachusetts State Trooper in my current home town of Natick sees a pristine old Lincoln Town Car puttering along at 16 MPH. He thinks to himself “This driver is just as dangerous as a speeder!” So he turns on his lights and pulls the driver over. As he gets out of his cruiser he notices that four elderly women are in the car. The three passengers are horrified — wide-eyed and white as a sheet — but the driver is calm and collected. The driver says, “I don’t understand why you’ve pulled me over.” The officer replies, “Ma’am, you weren’t speeding, but you should know that driving much slower than the speed limit can also be a danger to other drivers.” “Slower than the speed limit?” she says. “No, I was doing exactly the speed limit. 16 miles per hour, just like that sign says,” pointing to the sign beside her car. The State Trooper laughs and explains that the sign was the route number, not the speed limit. A bit embarrassed, she thanks the officer for pointing out her error. “But before I let you go, Ma’am, I have to ask,” he says, looking at her three still-agitated passengers. “Is everyone in this car OK? Your passengers seem awfully shaken and they haven’t said a peep this whole time.” “Oh, they’ll be all right in a minute officer. We just went through Wellesley on Route 135.”
