Two of the most important factors that go into determining the underwriting risk on motorized vehicles are: performance capability and retail cost. The most commonly available providers of auto insurance have underwriting restrictions against vehicles that are either designed to be capable of higher speeds and performance levels, or vehicles that retail above a certain dollar amount. Vehicles that are commonly considered luxury automobiles usually carry more expensive physical damage premiums because they are more expensive to replace. Vehicles that can be classified as high performance autos will carry higher premiums generally because there is greater opportunity for risky driving behavior. Motorcycle insurance may carry lower property-damage premiums because the risk of damage to other vehicles is minimal, yet have higher liability or personal-injury premiums, because motorcycle riders face different physical risks while on the road. Risk classification on automobiles also takes into account the statistical analysis of reported theft, accidents, and mechanical malfunction on every given year, make, and model of auto.
On 1 March 2011, the European Court of Justice decided insurance companies who used gender as a risk factor when calculating insurance premiums were breaching EU equality laws.[42] The Court ruled that car-insurance companies were discriminating against men.[42] However, in some places, such as the UK, companies have used the standard practice of discrimination based on profession to still use gender as a factor, albeit indirectly. Professions which are more typically practised by men are deemed as being more risky even if they had not been prior to the Court's ruling while the converse is applied to professions predominant among women.[43] Another effect of the ruling has been that, while the premiums for men have been lowered, they have been raised for women. This equalisation effect has also been seen in other types of insurance for individuals, such as life insurance.[44]

Auto insurance isn’t only great protection for your vehicle, it’s also the law. All states require some degree of insurance for your vehicle to protect you and other motorists. Coverage requirements will vary based on your financial responsibility for your car and your state’s requirements. Some states even require you to have liability insurance before you even get a license.

Liability auto insurance protects you from that worst case scenario by providing a cushion between your assets and the amount you’re on the hook for. For this reason, choosing the right auto liability limits is the most important part of your car insurance quote comparison. NerdWallet typically recommends having at least as much liability coverage as your net worth.
