Looks like camera shake going on. Are you using a remote shutter release? Are you using mirror lock-up? If not, then you need to. Also, if you are shooting near the traffic the cars can cause enough wind to shake the camera, even on a tripod. The key is to make sure everything but the car lights are clear and sharp.

If you don't have a remote release, you can use the self-timer

There doesn't seem to be any point of focus in the image...

Looks like a nice first go at getting the technique down, as the others have said there looks like a bit of camera shake. With long exposures on a tripod you probably need to turn off the in camera/lens stabilisation as it can actually introduce vibration into the image. Some tripods have hooks on them, so you can hook your bag or something heavy on to help weigh it down and make it more sturdy.

A clearer, more interesting background would also help, and I find the big street light post on the left a bit distracting.

You did not say what White Balance you had set the camera to. The image is much too yellow.

The yellow might be on purpose, a correct reflection of the very yellow light some street lights offer.
