The trap is inside the I-90 Connector Tunnel leading to Logan International Airport. Police car was hiding behind the curve so that it wasn’t seen until after you are very close to the trap. The police officer would run just in front of the victim car and show to pullover using hands’ gestures. My question: Is it legal to make such traps in tunnels? As for me, I think there is a risk to hit the police officer or somebody else can hit you from your back, as cars following you behind don’t see you breaking due to curvature.
