Michigan drivers who renew or buy car insurance will have some new choices starting Thursday.

They can either continue with unlimited medical coverage, lower the coverage, or choose be to opt out entirely.

On average statewide PIP rates will drop 15.5% for those who maintain unlimited coverage because an annual $220 fee assessed on every vehicle to cover catastrophic claims is dropping to $100.

Motorists can avoid the Michigan Catastrophic Claims Association fee altogether — saving an additional $100 a year — by forgoing unlimited coverage and picking $500,000 of coverage or $250,000.
