TRENTON — Saturday is the last day that New Jersey will inspect motor vehicles for mechanical problems.

Inspection stations will just check emissions on vehicles five years or older starting Monday.

Motor Vehicle Commission administrator Raymond Martinez says the changes will save the state about $17 million. Most of the savings come from scrapping 2.4 million mechanical inspections and re-inspections performed each year and by shifting new car emissions testing back a year.

School buses, limousines, jitneys, taxis and other commercial-plated vehicles will still be checked for emissions and mechanical defects.

New Jersey will become the 30th state that doesn't look for bald tires, worn brakes, non-working lights and turn signals, and cracked windshields.
