You must complete either Form REG-4-A or Form REG-4-D to obtain a bond. You will not be issued a certificate of registration and cannot be legally registered to do business in Illinois until we receive your bond. How do I obtain a bond using Form REG-4-A?
A Bond Claim Must be filed within 180 days from the last date of furnishing work or materials on the job. Must be served in writing on the Secretary of Transportation, with copies to the prime contractor, subcontractor and the bonding company. May need to be followed up by a lawsuit.
