The simple answer is yes, you can drive onto Fire Island. Whether you should, however, is a whole different question. Cars aren't allowed on the majority of the island - you can drive to one of two state parks but you aren't allowed to exit them by car. The better option is to drive to a Long Island port, hop on a ferry and travel to Fire Island on foot.
You can drive from Long Island onto Fire Island over bridges at either end to the Robert Moses State Park and Smith Point County Park. You cannot drive onto or through the majority of the island and can only access it on foot by taking a ferry.
