License restriction codes — Florida Permit Test
License restriction codes on the Florida permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Driving without meeting a restriction printed on your license can bring a citation and a suspension.
A restriction is a condition of the license, so ignoring it is driving outside the license.
If you have a restriction on your license and do not comply with the requirements, you could receive a citation and have your license suspended.
Restriction B means the driver must wear glasses or contact lenses at all times when driving.
The eye test was passed with the glasses on, so the license was issued to you wearing them.
Corrective Lenses. This person must wear corrective lenses (glasses or contacts) at all times when driving a vehicle.
Restriction G limits the driver to daylight driving only, from dawn to dusk.
Some eye conditions only show up in the dark, and that is the driving this rules out.
Daylight Driving Only. (Dawn to dusk)
A Business Purposes Only restriction allows any driving needed to make a living, including work, school, church and medical trips.
It is meant to keep a life running, not to keep a driver off the road altogether.
Business Purposes Only. Driving privilege is limited to any driving necessary to maintain livelihood
An Employment Purposes Only restriction is narrower: it covers driving to and from work and on-the-job driving an employer requires.
This is the tighter of the two work restrictions, and mixing them up costs a license.
Employment Purposes Only. Driving privilege is limited to driving to and from work and on-the-job driving required by an employer or occupation.
A Probation-Interlock Device restriction means the driver may only drive a vehicle fitted with a device that locks the ignition.
The device tests the driver before the engine starts, which is when a drunk trip would begin.
Probation-Interlock Device. This person can only drive a vehicle that has a device that locks the ignition.
On the test
What can happen to a driver who ignores a restriction on their license?
A citation, and the license can be suspended. A restriction is a condition of the license, so ignoring it is driving outside the license. Official Florida Driver License Handbook, p.10: “If you have a restriction on your license and do not comply with the requirements, you could receive a citation and have your license suspended.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
