If you are worried about having to clip out at the light, try unclipping a little early, since you know the light is coming.

For the traffic be sure to wear bright colors. I'm a bg fan of day glow yellow, which seems to be this year's color for men. And definitely make eye contact and signal your intentions. I've found that a lot of drivers if they know I want to turn left will slow down to let me make the turn.

Try to have fun and enjoy the scenery.
