Not sure of the exact laws in your state but here in PA, you always hear about the same stipulations...cannot ride a passenger and can't ride at night while on a permit.
The problem is that the actual law states that in addition to no passengers and daylight only, you also have to be within eyesight of a licensed rider at all times. That then becomes the biggest problem, people thinking it's really easy to just pick up a permit, jump on a bike, and ride when in reality, they are just misinformed.
I will say this though....I signed up for the MSF classes right after I got my permit so I could get my license and the people that I saw passing that class and getting their license to legally ride was astounding. These people were almost dropping the bikes during the classes and clearly demonstrating a lack of riding skill, and yet when test time came after the three classes we had, they managed to not fail.
So in that respect, I think the MSF class makes it extremely too easy to obtain a license, at least here in PA.
