Several factors influence car insurance premiums, including the car's make and model. To secure the best rate, provide detailed information about all drivers, including birthdays and Social Security numbers, and use the car's VIN. Opting for a higher deductible can lower premiums, as claims are infrequent. Evaluate whether smaller claims are worth it, as they can affect future rates. Bundling auto insurance with other policies can yield discounts, and it's advisable to review your policy every three years to account for potential changes in rates.
