At 4:55 am on a Saturday morning Doraville police set up Eastbound on I-285 right before Spaghetti Junction, where the posted speed is 55mph. However, this area normally flows at 70mph+ during the day and evening. The enforcement gotcha is that the road becomes desolate in the late night/early morning – which presents ripe opportunity for police to pull over unsuspecting drivers, who are used to traveling at higher (though illegal) daytime and evening traffic flow speeds. Please be careful!
