The Louisiana Road Signs & Driver Knowledge Test is the written exam new drivers must pass before getting a learner's permit or license. It's administered through the Louisiana Office of Motor Vehicles (OMV), Department of Public Safety & Corrections, and for first-time applicants going through a driver education program, the knowledge and skills tests are given by the licensed driver education provider.
Overview
The knowledge test draws its questions from the Class D & E Driver's Guide and covers road signs, traffic signals, and pavement markings alongside general rules of the road and safe-driving practices. Road signs aren't a standalone test — they're one chapter within the same 40-question exam, so you'll see sign-recognition questions mixed in with the rest of the material.
- Signs, traffic lights, and pavement markings (the core road-signs chapter)
- Rules of the road and right-of-way
- Safe driving practices and vision standards
Cost and registration
There's no separate fee just to sit for the knowledge test itself, but getting your learner's permit afterward costs $32.25, which covers the base permit fee plus a $12.00 handling fee. An additional service fee of up to $6.00 may apply depending on where you apply — check the official OMV fee schedule for the most current breakdown.
