Final answer:
The fee to reinstate a license after a fourth OUI conviction varies by jurisdiction and can't be specified without knowing local laws. Reinstatement typically includes additional requirements beyond the fee.
Step-by-step explanation:
If your license was suspended for a fourth conviction for operating under the influence (OUI), the fee to have your license reinstated can vary depending on the state or country you are in. Since the question does not specify a particular jurisdiction, it is not possible to give a specific figure without knowing the relevant legal framework. However, typically this fee can be substantial due to the seriousness of the offense and the number of prior convictions.
Reinstating a driver's license after multiple OUI convictions usually involves not only paying a fee, but also fulfilling other legal requirements such as completing a substance abuse treatment program, undergoing a period without driving, or installing an ignition interlock device in your vehicle. It is crucial to consult your local Department of Motor Vehicles (DMV) or equivalent for accurate information.
