Finding car insurance for women is no different that finding coverage for anyone else. Sometimes women are considered a higher risk than men, but not always. Men are not typically distracted with things like putting on makeup or talking on the phone as much as most females are.
Depending on the age and location of the driver, some car insurance companies can rate women higher than men. Younger men, however, have a tendency to be more inclined to show off their driving skills (or lack thereof) to try and impress their friends or some nearby female. The risk of accidents, or speeding tickets will increase and the insurance companies will price the cost of their policies accordingly.
For women that are looking to save money on their car insurance, one of the best ways to do that is to simply maintain a good credit score. Why does a good credit rating lower your car insurance rates? Well, the companies have figured out that people that have higher credit ratings are typically more responsible in other aspects of their lives such as paying their bills on time, not being involved in drugs (theoretically) and having the ability to hold down a steady job. Basically, you are a stable, and productive member of society.
As a result, you are much less likely to drink and drive, cause accidents, get speeding tickets or be distracted by other situations. Therefore, you pose a smaller risk of financial loss for the insurance company. Because the risk is lower to the company, the cost to your is also lower since all insurance is actually the sharing of risk. You have structured your life to be less risky.
On a somewhat humorous note, women are also better at multitasking while driving than men are so they can also get lower car insurance rates simply due to this one factor. Like it or not, that is the way it is!
