In most insurance policies, it states that if the agent fails to notify the additional insured in a timely matter when insurance is either cancelled or insurance levels are lowered, they are responsible for any accidents/damages that occur during that time period. Also, with regards to cargo insurance, it does not cancel right away. It always takes 30 days to cancel a commercial policy, even when there is non-payment of monthly premiums. If I do not pay my insurance today, or if I decide to cancel my insurance today, my policy will have a cancellation date of 30 days from the date it was originally cancelled. So carriers have plenty or warning when an O/O cancels their policy, or loses their policy due to not keeping up with their monthly insurance premiums. I just wanted to clarify that to some of you guys who don't seem to understand how this all works. A driver can't cancel his insurance policy overnight and have it cancelled that exact day. There are a lot of steps involved in that process!
