Which penalties may be imposed upon a contractor by the Board?

The penalties that may be imposed upon a contractor by the Board typically include the ability to restrict, suspend, or revoke the contractor's license. Each of these actions serves as a disciplinary measure that addresses various infractions, ranging from minor violations to serious breaches of law or regulation.

Restricting a contractor’s license can limit the scope of work they are permitted to undertake, ensuring compliance with safety regulations or licensing requirements. Suspension temporarily halts a contractor’s ability to perform work under their license, often used for more severe infractions or noncompliance issues. Revocation is the most severe penalty and signifies that the contractor has lost their license entirely, prohibiting them from practicing in that capacity.

The other options list combinations of penalties that may not accurately reflect the standard disciplinary measures enforced by the Board. While fines, warnings, and probation can be part of regulatory actions in some contexts, they are not as commonly associated with the specific disciplinary authority of the Board in relation to contractors. Therefore, the correct answer provides a comprehensive view of the typical penalties available to the Board for regulating contractor conduct.
