There is no left turn allowed from NB Groesbeck onto 13 Mile Road for reasons that I cannot fathom. You can turn left off of NB Groesbeck at EVERY other intersection except this one. In order to do any business west of M-97 on 13 Mile, one has to either go up to the WOW! gas station and pull a u-turn in their parking lot or make some weird Michigan left in which you have to go up to Utica, make a right, come back down to 13 Mile, make another right, and then back to Groesbeck which entails waiting for three sets of lights and all kinds of consternation. That is if you are in the right lane to start with. If one is unfamiliar with the situation and proceeding in the left lane on Groesbeck as you approach 13 Mile forget about it, you are on your own.
