Louisiana doesn't publish its knowledge-test length and pass score on an official page we could confirm, so we don't state numbers here. The questions in this quiz are written in the style of Louisiana's knowledge test, and Louisiana's official driver handbook (linked below) is the source to study from.
Pick an answer on each question to see whether you got it right, with an explanation.
This is a short sample — DriveDrill has 200+ Louisiana questions
and full-length mock exams in the app.
Q1. In Louisiana, to pass the OMV knowledge test for a driver's license, you must correctly answer:
A 90 percent of the questions
B 80 percent of the questions
C 70 percent of the questions
D 60 percent of the questions
The Louisiana driver's guide states you must correctly answer 80 percent of the knowledge test questions to receive a passing score.
Q2. Blood alcohol concentration depends on:
A Only how much you drank
B Only how tired you are
C Only what you ate
D How much you drank, over how long, your body weight and other factors
Two people drinking the same amount can end up at very different levels, so nobody can judge their own BAC reliably.
Q3. In Louisiana, the move-over law requires you to change lanes, or slow down, when passing:
A Any stopped vehicle showing hazard lights or other warning signals
B Only vehicles stopped inside a marked work zone
C Only stopped police, fire and ambulance vehicles
D Stopped emergency vehicles and certain work or service vehicles showing warning lights, but not ordinary cars with hazard lights on
Move to a lane that is not next to the stopped vehicle when you safely can. When you cannot, slow down. People working at the roadside are struck every year by drivers who did neither.
Q4. In Louisiana, a learner permit must be held for at least how long before the road test?
A 3 months
B 30 days
C 9 months
D 6 months
The holding period exists so new drivers practise across seasons and conditions rather than cramming a licence in a weekend.
Q5. The most common cause of freeway merging crashes is:
A Driving in the right lane
B A speed difference between merging and through traffic
C Signalling too early
D Too many lanes
Match the speed of traffic before you merge; joining at 40 mph into 65 mph traffic is what causes the problem.
Q6. Before you turn or change lanes, you should signal:
A After you have started to move over
B Only if another vehicle is nearby
C Well before the turn so other drivers can react
D As you begin the turn
Signal early and continuously. A signal given as you are already turning tells other drivers nothing they can use.
Q7. The safest place to be around a large truck is:
A Where you can see the driver's mirrors
B Directly behind it
C Beside its right rear wheels
D Directly in front of its bumper
If you cannot see the driver's face in the mirror, they cannot see you. Trucks have large blind spots on both sides, in front and behind.
Q8. Seat belts work best because they:
A Stop the car faster
B Keep you in position and let the strongest parts of your body absorb the force
C Are only needed on highways
D Prevent the airbag from deploying
Belts keep you behind the wheel and away from the windshield, and they position you correctly for the airbag.
Q9. In Louisiana, the maximum posted speed limit on urban interstate highways is:
A 65 mph
B 60 mph
C 75 mph
D 70 mph
Urban interstates are held to a lower maximum than open rural highway, because of interchange spacing and traffic volume.
Q10. A U-turn should never be made:
A On a residential street
B On a curve or near the crest of a hill where you cannot be seen
C In a parking lot
D At an intersection with a signal
You need to be visible for the whole manoeuvre. Blind curves and crests hide you from traffic that arrives at speed.
