A state trooper (sometimes an undercover) will sit at the corner of Bowen and Bullis, just outside of the Sunoco parking lot and looks for every little infraction of cars driving by, such as no turn signal, out of date registrations, and of course speeding. Be careful since Bullis Road is only 45 mph and the majority of traffic is not driving that slow. Been stopped by troopers on Bullis Road before and they have zero tolerance for speeding.
