When are “P” and “S” endorsements required?
Drivers who operate passenger-carrying commercial motor vehicles (CMVs) requiring a commercial driver’s license (CDL) per 383.5 must have the correct endorsement(s). Endorsement questions do not always have a simple answer, depending on the circumstances.
This article covers the basics with the “P” (passenger) and “S” (school bus) endorsements and a few less common scenarios.
Endorsement basics
CDL passenger-carrying vehicle drivers may be required to have one or both endorsements below as part of their CDL driving privileges. The following guidance is from Part 383:
- Passenger-carrying vehicle requiring a “P” endorsement: A CDL CMV designed to carry 16 or more passengers, or the vehicle is 26,001 pounds or greater and is designed to carry any number of passengers.
- School bus or vehicle requiring an “S” endorsement: A CDL CMV used to transport pre-primary, primary, or secondary school students between home and school, or to and from school-sponsored events. A school bus endorsement does not include operations of a for-hire motor carrier.
Both endorsements require prior completion of the respective Entry-Level Driver Training (ELDT) module from an entity on the Training Provider Registry (TPR).
- ELDT “P” endorsement training covers operating a passenger-carrying CMV, learning how to load and unload passengers, responding to emergencies, handling troublesome passengers, and other tasks.
- ELDT “S” endorsement training covers how to load and unload children, properly operate the lights, stop signs, and other warning devices on the school bus, and other needs specific to transporting children on a pre-determined bus route to and from their homes and schools.
Both endorsements also require knowledge and skills tests administered by the driver’s CDL licensing authority once the respective ELDT training module is complete. To be eligible for the “S” endorsement tests, a driver must first have their “P” endorsement.
It is important to note that individual states may require special permits to drive non-CDL passenger-carrying CMVs.
Also, drivers operating vehicles that weigh less than 26,001 pounds and are manufacturer-rated for at least nine passengers and fewer than 16 passengers, including the driver, are regulated CMVs but are not required to have a CDL or either endorsement.
Endorsement scenarios
The required endorsements are not always clear when school buses and modified passenger-carrying CDL vehicles are involved.
School buses:
The “P” and “S” endorsements are tied to passenger movement. However, per interpretation 10 from 383.93, only a “P” endorsement is required for operating a school bus when:
- Delivering school buses from the manufacturer,
- Operating empty school buses on test drives, and
- Driving to and from events not sponsored by a school.
Modified vehicles:
A couple of key points on vehicles initially designed to carry passengers are:
- A modified vehicle that no longer carries passengers does not require a CDL unless it is 26,001 pounds or greater, or hauls placardable hazardous materials per interpretations 1 and 11 in 383.5.
- Passenger-carrying CMVs that are 26,001 pounds or greater, modified to have no passenger seating, do not require a “P” endorsement.
The following table covers several endorsement scenarios based on current federal regulatory guidance.
Scenario | No endorsement | P endorsement | S endorsement |
---|---|---|---|
Between school and home or to school-sponsored events | X | X | |
Non-school sponsored after school events | X | ||
Mechanic or manufacturer’s representative test drive of an empty school bus | X* | ||
Modified passenger-carrying CMV of 26,001 pounds or more with passenger seating | X | ||
Modified passenger-carrying CDL CMV with no passenger seating | X | ||
Driveaway-towaway from a manufacturer | X* |
Key to remember: When drivers operate passenger-carrying CDL CMVs, be sure which endorsement(s) are needed, if any.
