If a driver is involved in an accident affecting multiple parties, what is essential to provide?

Providing the insurance policy number and expiration date is essential in the event of an accident involving multiple parties. This information is crucial because it allows all affected parties to verify coverage, assess liability, and ensure that claims can be submitted efficiently. When multiple individuals are involved, clear communication regarding insurance helps facilitate resolution and protects the interests of everyone involved.

In addition to ensuring that each party's insurance obligations are met, having the policy number on hand can assist in expediting the claims process, which is particularly important in complicated accidents with multiple claimants. The expiration date is also significant because it confirms whether the coverage was active at the time of the accident.

Having only a vehicle registration number, a name and address, or minimal information could lead to legal complications or disputes about coverage and responsibilities, which makes option A the best choice for effective accident management and resolution.
