According to Louisiana Department of Public Safety - Office of Motor Vehicles, “Applicants must pass a vision test and have 20/40 vision in one eye and also pass a 40 question test with a minimum score of 80%.”[1]
The Louisiana Department of Public Safety, Office of Motor Vehicles, sets the rules for the Class E driver's license. Before a license is issued, the knowledge and skills tests must be completed. The driver education provider administers the knowledge test and the skills test, and all road skills tests must be performed at a driving school. Because the provider runs the test, check with yours about scheduling and what to bring.
The knowledge test has 40 questions, and an 80% is the minimum passing score. Applicants must also pass a vision test, with 20/40 vision in one eye. If you fail the knowledge exam, you may retake it once on the same day, if time allows. That depends on the provider's schedule, so do not count on it.
The basic Class E license fee is $32.25, and a local service fee of up to $8 may be added. A Class E license expires on your birthday in approximately 6 years from the date of issuance. Renewal is $32.25, with a $15 late fee after 10 days expired.
Other details, such as documents required and provider-specific policies, can vary. Confirm them on the official Louisiana Office of Motor Vehicles site (expresslane.la.gov/omv) before you go.
Prepare for the LA DMV - Louisiana Department of Motor Vehicle exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: What shape is always used for railroad crossing advance warning signs in Louisiana?
Answer: C. Circle
Explanation:
The correct answer is circle. Railroad crossing advance warning signs are round and yellow, and the shape tells you what the sign is before you can read it.
An octagon is reserved for stop signs, so it never signals a railroad crossing ahead. A rectangle is used for regulatory and guide signs, such as speed limits and route information. A diamond is the common shape for most other warning signs, such as curves or intersections, which is why it is the tempting wrong answer here.
Rule to remember: the circular yellow sign is the exception among warning signs. When you see it, slow down, look and listen for a train, and be ready to stop.
Question: If you encounter issues with the DMV’s online services, which of the following is the recommended course of action?
Answer: B. Call the DMV Customer Service
Explanation:
The correct answer is to call DMV customer service. A phone call puts you in direct contact with a representative who can troubleshoot the problem, explain the procedure and tell you what to do next.
A written complaint is slower and does not solve the immediate issue. Posting on social media is not an official support channel and may expose personal details. Visiting a DMV office without an appointment can mean a long wait and may not help if the problem is with the online system itself.
Rule to remember: when an online service fails, start with the official support line before taking other steps, and keep notes on what happened and what you tried.
Question: What windshield condition would cause a vehicle to fail a Louisiana safety inspection?
Answer: B. A crack in the driver's line of vision
Explanation:
The correct answer is a crack in the driver's line of vision. Damage there can block or distort what the driver sees, so it is a safety problem and can cause a vehicle to fail inspection.
Minor surface scratches do not affect visibility in a meaningful way. Small chips outside the driver's line of vision leave the view ahead clear. Tinted windows with a legal tint percentage are allowed by definition, since the tint meets the legal limit.
Rule to remember: inspectors look at whether a defect interferes with the driver's view. Location matters as much as size, so damage in the line of vision is the problem.
Start with the Driver's License set at LA DMV Driver's License to see which topics you already know. Note the questions you miss, and read the matching section of the official Louisiana driver's guide before returning to them.
Next, work through the topic sets one at a time: Road Signs and Signals, Traffic Laws and Road Rules and Vehicle Safety and Inspection. After each set, read the explanation for every question, including the ones you got right, and write the rule in your own words.
Then cover the administrative topics: Insurance Requirements, Vehicle Registration and Fees and Payments. Check fee amounts against the official site, since they can change.
In the last few days, take the full practice test and treat any miss as a prompt to reread the official material. Because the real test needs 80%, aim to score above that line consistently on our sets. Our questions are written by us and are not real exam questions.
