Is there a statute of limitations on a DUI bench warrant?

The fact is that warrants never expire. Additionally, as to the underlying charge, the statute of limitations only has to do with the time in which charges must be filed. Since one has already been filed, it does not apply in this case. The only way to handle this is for you to turn yourself in. Otherwise you will be looking over your shoulder until you are taken into custody. And make no mistake, in time this is just what will happen.

At this point, you need to speak with an attorney ASAP in the area where the warrant was issued. They'll advise as to the best way to handle things.
