Final answer:
The duration of a suspension for accumulating 8 points in 18 months depends on local laws and cannot be accurately provided without knowing the specific jurisdiction.
Step-by-step explanation:
When someone accumulates 8 points within 18 months on their driving record and receives a suspension, the typical duration of that suspension varies by jurisdiction. However, if we had to select from the given options without specific jurisdiction information, we'd need to refer to common practices or a specific state's or country's Department of Motor Vehicles (DMV) or the equivalent authority's regulations.
Without this information, it is difficult to give a definitive answer. Generally, suspension times can vary based on the severity of the offenses and the specific rules in place where the suspension was issued. It's important to consult the local DMV or a legal professional for the most accurate information.
