Make sure between 7:30am-8:30am and 2:30pm-3:30pm you go 15 down Merriman at the Ridgewood Elementary School Zone. Cops sit out there in the Morning with a gun in the school’s parking lot and you dont notice them until you get right up on them. Radar Detectors dont necessarily work because they shoot the radar when they see you coming, so if your speeding, detectors wont help. If its the mounted dash unit, same thing, they wait until they see you coming up the road and turn it on, so its too late when your detectors come on because you’ve been nailed. They will especially write tickets for 29 and above in the 15 zone.
