Yes, but if the vehicle is subject to the limits, then you can only enter the amount up to the limit (prorated based on business percentage). [EDIT: You added the weight after I started my post, so it seems like the limits won't apply to you.]
However, is there a reason why you are wanting to use Section 179 rather than Bonus Depreciation? For Federal taxes, Bonus has fewer complications than Section 179. However, some states treat Section 179 differently than Bonus, so that may have an impact.
