Final answer:
The renewal frequency of a driver's license for individuals aged 18-65 varies by state and can range from every 4 to 8 years. Drivers need to check their state's specific renewal requirements with their local DMV.
Step-by-step explanation:
The frequency at which drivers between the ages of 18-65 should renew their driver's license every few years can vary by state. Each state has its own Department of Motor Vehicles (or equivalent) and sets its own renewal periods. In some states, the renewal period might be every 4 years, while in others it might be longer, such as every 5 to 8 years. Drivers should check with their local DMV or equivalent agency to find out the specific rules that apply to them. All drivers need to stay informed about the renewal requirements to ensure they keep their driving privileges and stay compliant with state laws.
