CDL Exemption Renewal: NSTA Seeks to Skip Engine Compartment Inspection

FMCSA Seeks Comments on NSTA Exemption Renewal for School Bus CDL Applicants

The Federal Motor Carrier Safety Administration (FMCSA) has published a notice requesting public comment on the National School Transportation Association's (NSTA) application to renew an exemption that allows all commercial driver's license (CDL) applicants seeking only a school bus endorsement to forgo the engine compartment portion of the pre-trip vehicle inspection skills test. The notice was published on June 30, 2026, and the comment period is open for 30 days.

This exemption has been in place for several years and is intended to streamline the testing process for school bus drivers, who typically operate vehicles with accessible engine compartments and have limited need for under-hood inspection skills. However, the renewal has sparked debate about safety standards and the integrity of the CDL testing process.

Background of the Exemption

The NSTA originally applied for this exemption in 2018, arguing that the engine compartment inspection requirement was unnecessary for school bus drivers because:

• School buses are typically maintained by fleet mechanics.
• Drivers rarely need to open the hood during daily operations.
• The time and cost of training for this specific skill outweigh the safety benefits.

The FMCSA granted the initial exemption in 2019, and it has been renewed periodically since. The current renewal application seeks to extend the exemption for another five years.

What the Exemption Covers

Under the exemption, CDL applicants who are only seeking a school bus endorsement (not a full Class A or Class B CDL) are not required to demonstrate proficiency in the engine compartment portion of the pre-trip inspection. They must still complete all other parts of the pre-trip inspection, including:

• Exterior lights and reflectors
• Tires and wheels
• Brake system
• Coupling devices (if applicable)
• Emergency equipment

Industry Reaction

The exemption has been controversial. Some safety advocates argue that skipping the engine compartment inspection could lead to missed maintenance issues, potentially causing breakdowns or accidents. Others counter that the exemption is practical and does not compromise safety, as school bus drivers are not expected to perform mechanical repairs on the road.

In a related regulatory development, the FMCSA recently revised truck emission rules, which may affect fleet maintenance practices. For more on that, see our article: EPA Revises Truck Emission Rules: Did It Go Far Enough?.

Impact on CDL Holders and Carriers

For CDL holders, this exemption means that if you are pursuing a school bus endorsement only, you can save time and money on training. However, if you later decide to upgrade to a full CDL, you will need to pass the engine compartment inspection as part of the full skills test.

For carriers, especially school bus operators, this exemption can reduce the burden on new hires. However, it also places greater responsibility on fleet maintenance teams to ensure vehicles are road-ready.
