Is $30,000 enough coverage for a significant accident? Of course not. Maryland has had 20/40 limits since 1972. This is 102,000/204,000 in 2010 dollars. But Rome was not built in a day, and this bill is a good step in the right direction.
As odd as it is for me to be carrying water for insurance companies, the only way to protect yourself from an uninsured or underinsured motorist is to make sure you have adequate uninsured motorist coverage. The relatively modest increase in premium is worth the additional protection.
