I am applying for my general contractor's license and I have to do a balance sheet as part of the application. I need to be able to show $17,000 in working capital. The balance sheet has current assets, current liabilities; ( I assume these for working capital) then the lower part has fixed assets, long term liabilites. What do I need to include in the current asset category other than cash on hand? Can I include vehicles and equipment as assets for this purpose?

The definitive answer will come from the instructions included with the blank balance sheet form you received from the licensing board. The instructions should provide guidance and definitions as to what's "current" and what's not.

Absent any instructions otherwise, vehicles and equipment are considered long-term assets.
