Unexperienced driver laws

Here in Canada, at least in a couple of provinces, the car you're driving has to display an L if you're learning to drive or an N if you're a new driver. I don't know the period of time the letters have to be displayed.

P plates in England, Scotland and Wales.

You can display green ‘probationary’ P plates to show that you’ve just passed your driving test. You do not have to display them. You can leave them on your vehicle for as long as you like.

Nothing here in the United States , and out there in California it shows: they drive like maniacs - if they indeed have a driver license to begin with.

In Victoria, Australia a red P plate is required for the first 12 months after getting a licence, then a green P plate for a further 3 years. They're compulsory and not displaying them can result in a fine and 3 demerit points.

I've not heard of having anything on your car showing you are an inexperienced driver in the US, but most states do have restrictions on drivers that are under 18 and/or have only had their license for a certain amount of time. Things like they cannot have another young person in their car besides a family member, they cannot drive during certain hours, things like that.

We don't have many drivers under 18 over here. One has to be seventeen before one can drive a car on the road as a learner, and until you pass your test you cannot drive a car without L plates and a driver with a full licence in the passenger seat.

After that there are no restrictions.
