Bodily Injury Liability limits are generally sold at limits of 25/50, or 50/100, or 100/300, or 250/500. (Abbreviated to 25/50 instead of 25,000/50,000)  There is no crystal ball predicting if you will ever need your auto liability insurance. You buy insurance to protect you when you are involved in an accident. You sure wouldn’t plan to rear end another car but accidents do happen. In the event it happens, you want to be sure you have the coverage needed to protect your assets.  The third number normally in the above sequence is the limit relating to the property you damage. It usually is found in increments of $25, $50 or $100 thousand.
