Yes. It's a left turn arrow controlled turn with two lanes so not that bad.
Depends a bit on where you are heading though. I'm frequently heading to the east side of Gtown but prefer to bail off Wisconsin at Reservoir or Q Street and head into the back streets to find parking. Saves having to make a second and much more difficult left off of M onto 31, 30, 29th, etc. If you are just transiting through it's a fine option.
