The validity of the insurance plate on your bike has expired. What are the consequences for its use on public roads?

You answered correctly. If the insurance plate on your bike has expired, you are not allowed to ride the bike on public roads. However, you may push the bike on the pavement, as pushing is not considered driving. Parking the bike in a car park is not relevant to this rule; the issue is using the bike in traffic without valid insurance. Always make sure your insurance plate is current before riding, as driving a motor-assisted bike with an expired plate is illegal and can result in fines and other penalties.
