Confirm the L Restriction
Review your CDL and Pennsylvania’s current application, permit, fee and scheduling requirements.

Prepare to demonstrate air-brake knowledge, inspect a full air-brake system and safely operate an air-brake-equipped commercial vehicle.
The L restriction means you may not operate a commercial motor vehicle equipped with air brakes. It is generally placed on a CDL when the driver completes the skills test in a vehicle that does not have an air-brake system.
Removing L can expand the trucks, buses and fleet vehicles you may legally operate, provided you hold the correct CDL class and any required endorsements.
Patriot CDL provides focused preparation; PennDOT controls licensing and testing.
PennDOT requires an air-brakes knowledge test, a full vehicle inspection and an on-road test. A basic control skills test is not listed for this restriction-removal process.
Review your CDL and Pennsylvania’s current application, permit, fee and scheduling requirements.
Pennsylvania requires the air-brakes knowledge test before the restriction-removal skills test.
Arrange a representative vehicle equipped with a full air-brake system for inspection and road testing.
In Pennsylvania, complete the full vehicle inspection and on-road portions of the CDL skills test.
After passing, follow PennDOT’s process to receive a CDL without the L restriction.
Current CDL holders removing only the air-brake restriction must complete the full vehicle inspection and on-road segments in Pennsylvania. FMCSA does not require ELDT solely for L-restriction removal.
Review PennDOT RequirementsUnderstand system components, safe operating limits and required checks.
Correctly inspect and explain the air-brake system and vehicle safety components.
Demonstrate safe operation in a representative air-brake-equipped CMV.
Confirm permit, waiting period, fees and vehicle documentation with PennDOT.
Clear answers about the no-air-brake restriction, testing and ELDT.
An L restriction means the driver is not authorized to operate a commercial motor vehicle equipped with air brakes. It is generally applied when the CDL skills test is taken in a vehicle without an air-brake system.
L prohibits operation of a CMV equipped with any air-brake system. Z applies when the driver tested in a vehicle with an air-over-hydraulic system and prohibits operation of a CMV equipped with a full air-brake system.
PennDOT requires the air-brakes knowledge test, a full vehicle inspection and an on-road test in an air-brake-equipped commercial vehicle. PennDOT’s current table does not list a basic control skills test for air-brake restriction removal.
No. FMCSA states that drivers removing the no-air-brake L restriction under 49 CFR 383.135(b)(7) are not subject to the Entry-Level Driver Training regulations solely for that restriction removal.
ELDT is not federally required solely to remove L. Focused instruction and practice may still help you understand air-brake components, complete the inspection correctly and safely operate the test vehicle.
