Final answer:
You must stay at the scene of a vehicle crash for a significant time to exchange information, help the injured, and cooperate with law enforcement, with the exact time depending on the incident's circumstances and severity.
Step-by-step explanation:
When you are involved in a motor vehicle crash, the law typically requires that you stay at the scene for a significant period of time. This duration serves several purposes: it allows you to exchange information with other involved parties, assist anyone who may be injured, and cooperate with law enforcement officers when they arrive. There is no universal time you must stay, as it can depend on the circumstances of the crash and the severity of the incident. However, leaving the scene of an accident, particularly where injuries or significant damage occurred, without fulfilling your legal responsibilities can result in serious penalties, including criminal charges.
