I have seen both Henrico County AND Virginia State Police officers/troopers running radar and lidar (laser) at the Nine Mile Road exit of Interstate 64. They focus on westbound traffic where the speed limit drops from 65 to 55, which is "easy pickings" since nobody ever slows down there. 🙁

As you crest a very slight hill going westbound, the officer will already have spotted you and measured yours speed. He will be sitting inside the "cloverleaf" of the Nine Mile Road exit – just beyond the overpass. They can hide in plain signt, so to speak. If they face you straight on, they’ll probably be using radar.

If the cruiser is parked perpendicular to the highway and the driver’s window is down, he is likely using lidar/laser – which can pick out one car from a crowd. Both are accurate, of course, but the laser can only be used from a stationary position and the officer has to "look through it" to zap a particular vehicle.

You have been warned!
