The answer is yes, depending on the type of car accident.
If you were NOT injured: You probably don’t need an attorney because your case is “property damage only”. That means the only thing you’ll be discussing with the insurance company is getting your car fixed or getting a check to replace your car. Getting an attorney to deal with the insurance company for just your car would probably not be worth it for you in the end.
If you are an Injured Driver: If you were hurt, and the accident WAS NOT your fault, you probably have a valid claim and will want to talk to an attorney (consultations are free) to help protect your from the insurance company. (If the accident was your fault, a personal injury attorney wouldn’t be the right fit for your case).
If you are an Injured Passenger: If you were hurt in the accident, and you were a passenger, it doesn’t matter whether the driver of the vehicle you were in was at fault, or if it was another driver’s fault, you may still have a valid claim, and talking to an attorney would be wise (consultations are free).
