What happens if you are caught by the police without L plates on your car or motorbike while you have a learner licence?

The correct option is:

1. 25 demerit points and a $100 fine

In New Zealand, if you are driving a car or motorcycle with a learner’s license (L plate), you must ensure that the L plate is clearly displayed on the front and back of the vehicle. The purpose of this regulation is to inform other road users that you are a learner driver and may need more time and space to perform certain maneuvers. If you do not display the L plate, the police have the authority to penalize you, including deducting 25 demerit points and imposing a $100 fine.
