First, wave “hello”
So you were driving down the road a little faster than you should have been, and you spot a police cruiser lurking behind some shrubbery. One former police officer says that the smartest thing that you can do right then is to wave at the officer. Why? He will either think that you know each other and wave back, or will think that you’re acknowledging that you were driving too fast, and are letting him know that you’re slowing down. Either way, you drastically reduce your chance of getting a ticket.
