People usually take out their basic driving license at about the age sixteen. This is the minimum age limit for a basic license, and everyone will prepare for it, or ones who are on their way to becoming employed in a couple of years. Some are lucky enough to have families which have extra vehicles that younger drivers can use.
High school is the start of your driving life, and you could have the license to do it. Besides this, you might also need the high school parking permit to safely park your vehicle inside a campus. Usually, most students can forego driving and this document by having their folks take them to or from school.
However there are students who have the experience and the vehicles to park, and the prevailing wisdom is that the earlier you get to be familiar with these, the more you are able to use it later on. But this is primarily a lifestyle decision for both families and young drivers.
The high school is managed by folks who know how the young behave and so will always make their system work with a maximum need for being responsible. For instance, a permit for a student may have grade and behavioral requirements. The more well behaved, those having higher grades and the like may be eligible for it.
However, this is something that could be prejudicial to those who have different sets of social circumstances. So more often than not high school admins will make the permit available on a first come first serve basis. They might even give equal opportunities to both staff or teachers and the students.
In this way the permit can be applied to and gotten when you prepare for it. That is, you come earlier on the day it is issued or available, and you do not have to present grades, simply a valid ID. There might be a system in place that disqualifies those who have had it in a previous semester or school year.
The document, like licenses has a limited valid period for use. They might expire after one semester or after a year. This gives everyone the opportunity to get it and at the minimum have a lot less worries about where they parked their cars, since those inside a school is well protected by walls and security personnel.
Others otherwise not eligible or qualified and who have not gotten it through the periodic application can take their chances on streets and curbs near the campus. Streets that have no parking stripes cannot be parked on, but most people will park where there is less traffic. So you could either have a parking ticket, which is most likely, or risk your car being broken into and your stuff stolen.
The other alternative will cost, and sometimes it might even have more security. There are pay for parking lots, but they may not even be close to the campus. It all depends on where you are located, but the permit in question is always something useful under the circumstances.
