Answer: The premium you pay is a direct reflection of your driving record for the past three to five years depending on the insurance company. Insurance companies order driving records from the DMV of your residence state and from other states where you've been licensed. Statistics show that drivers with tickets and accidents are more likely to have accidents than drivers with clean records.
Answer: This is called a misquote. Determining your premium depends on many factors, including where you live, the kind of car your drive, how much you drive, how much coverage you want, your driving record, and your age.
If an error is made in reporting any of these facts, your rates won't be quoted correctly. Misquotes can also happen if your agent makes a mistake in applying the company's rating system. Auto insurance misquotes can happen when your application information differs from your actual driving record.
Companies ask states' motor-vehicle divisions to verify the records of drivers they insure. If you told your insurance agent you have a perfect driving record, and you don't, your insurance company will charge higher premiums than your agent quotes.
To avoid misquotes, provide accurate information about your driving record and any other facts affecting the cost of insurance, such as the make of your car or how far you commute to work. Verify all information before signing the application.
Answer: Liability is required in every state unless you can prove financial responsibility otherwise. Requirements for financial responsibility and minimum liability requirements can be found on your state insurance commissioner's page here. Limits vary widely from state to state and, if you carry the minimum limits, when you drive into another state you will automatically assume that state's minimum liability requirements.
Answer: Collision coverage is when you have a collision with something like another car. Comprehensive coverage is when it is anything else other than a collision such as fire or theft. Most people would have both coverage's when using the car on a regular basis. Sometimes when one is just storing a car they may only keep comprehensive coverage since they are not using it on the road therefore, it is unlikely to be in a collision.
Answer: It is generally accepted among insurance agents that the state minimum policy limits are not enough. Most insurance professionals would agree for the average driver the best liability limits to have are 100/300/100. This means:
$100,000 per person for bodily injury
$300,000 per accident for bodily injury
$100,000 per accident for property damage
Since in most areas medical treatment is in fairly the same range, the last limit, per accident for property damage, is the one you may want to take into account if you are not the average driver. If you live in an area where you feel that if there was an accident, that was your fault, and property damage may exceed $100,000, you may want to consider higher limits. Remember, property damage is the other person's car and any other property damaged during the accident if you are at fault. In some areas one's landscaping can cost over $100,000!
