Section 1: 12 Key Topics Covered on the CDL Passenger Endorsement Test
1. Pre-Trip Inspection for Passenger Buses
Pre-trip inspections for passenger buses go beyond what's required for a standard commercial truck. The focus is on passenger safety and a safe onboard environment. Before every trip, the driver must thoroughly inspect the interior: seat bolts must be secure with no looseness, handrails and grab straps must be firmly attached to prevent injury during travel. All interior lighting (including step lights and night lighting) must be fully functional, windows must be free of cracks, and the heating and air conditioning systems must operate properly.
2. Passenger Loading and Unloading Procedures
Passenger bus drivers must follow strict safety procedures when stopping to pick up or drop off riders. The door must never be opened until the bus has come to a complete stop and the parking brake is fully set. While passengers board and exit, the driver must carefully monitor all mirrors — especially the blind spots along the right side of the bus. Only after all passengers have safely stepped onto the curb and cleared the yellow safety line should the driver close the door and release the brake.
3. Luggage and Cargo Safety Rules
No luggage or cargo may be stored in a way that blocks the aisle, emergency exits, or the driver's line of sight. Large bags must be placed in the designated undercarriage baggage compartment whenever possible. If a passenger must bring a carry-on item aboard, it must be secured in the overhead rack, which must have a restraining net or door to keep items in place. Any loose item that could become a projectile during a hard stop or collision is not permitted in the passenger cabin.
4. The Standee Line Rule
Federal law is absolute on this point: no passenger may stand forward of the standee line (also called the white or red line near the front door) while the bus is in motion. This area overlaps with the driver's critical field of vision and mirror blind zones. Once the bus begins to move, Passengers must not stand forward of the standee line while the bus is moving. The driver must ensure passengers remain safely positioned before operating the vehicle.
5. Emergency Exits and Escape Windows
Every day before going into service, the bus driver must physically test each emergency exit and escape window on the vehicle. Handles must not be rusted or stuck — each exit should push open easily from the inside with moderate force. Additionally, when any emergency exit is opened — whether intentionally or accidentally — the red warning light and audible alarm in the driver's cab must activate automatically and immediately.
6. Wheelchair Lifts and ADA Compliance
Under the Americans with Disabilities Act (ADA), commercial bus drivers must be proficient in operating the wheelchair lift using both the powered and manual backup systems. When assisting a passenger in a wheelchair, the lift platform must be locked in position and the vehicle must remain level and stable. Wheelchairs must be secured using the vehicle manufacturer's approved securement system, and passengers should use available occupant restraint systems according to equipment requirements.
7. Railroad Crossing Requirements — A Top Test Topic
Railroad crossings are among the highest-priority topics on the CDL Passenger permit test — and they have zero tolerance for errors. Most buses and commercial passenger vehicles must stop at railroad crossings between 15 and 50 feet from the nearest rail before crossing. The driver must stop, look and listen for trains, and proceed only when the crossing is safe. Exceptions may apply in certain situations, such as when directed by law enforcement or where local regulations provide an exception. After stopping at a railroad crossing, the driver should open the driver-side window, turn off unnecessary noise sources, and carefully look and listen for approaching trains. Some buses may require opening the passenger door according to vehicle design or state regulations. Only after confirming the tracks are clear and closing the door may the driver proceed. The critical rule: never shift gears while crossing the tracks. Select a low gear before crossing and maintain it all the way across to prevent the bus from stalling on the tracks.
8. Hazardous Materials Restrictions on Passenger Buses
Passenger vehicles have strict restrictions on transporting hazardous materials. Drivers must understand which hazardous materials are prohibited, which may be transported under limited exceptions, and how DOT hazardous materials rules apply to passenger-carrying vehicles. Certain limited exceptions may allow passengers to carry specific personal medical items or other permitted materials, but drivers must understand DOT hazardous materials restrictions and company policies before allowing items onboard
9. Accident Procedures and Emergency Response
If a passenger bus is involved in a crash or breakdown on a public roadway, the driver's first responsibility is the safety of all passengers — not assessing vehicle damage. The driver must evaluate the risk of fire or a secondary collision to determine whether an emergency evacuation is necessary. If evacuation is required, passengers must be guided to a safe area completely off the roadway and well behind any guardrails. Under no circumstances should passengers be left standing or walking on an active highway.
10. Fire Extinguisher Requirements
Passenger-carrying commercial vehicles must carry a properly charged and secured fire extinguisher meeting FMCSA requirements. The required rating depends on the vehicle operation and whether hazardous materials are transported. The pressure gauge needle must be in the green zone at all times. The extinguisher must be mounted in a bracket that keeps it accessible to the driver at all times, and its tamper seal must be intact.
11. Emergency Warning Triangles
If a bus is forced to stop on the side of the road, the driver must place three red reflective triangles within 10 minutes of stopping. On a two-lane, two-way road, the triangles are typically placed 100 feet in front of the vehicle, 10 feet behind it, and 100 feet behind it — giving oncoming traffic enough distance to slow down and stop safely.
12. Managing Passengers While Driving
While the bus is moving at highway speeds, the driver must never engage in extended conversation with passengers or allow any interaction that causes distraction. If a passenger becomes drunk, aggressive, or disruptive, the driver must not eject them at a random or unsafe location along the route. The correct procedure is to continue to the next safe, staffed location — such as a rest stop, gas station, or a stop with law enforcement present — and transfer the situation to the appropriate authorities.
Section 2: How to Get Your CDL Passenger Endorsement — Step by Step
For first-time CDL applicants, earning the Passenger (P) Endorsement generally requires completing the following five steps:
- Pass the General Knowledge Test: This is the foundation of every CDL. The General Knowledge exam has 50 questions and covers core commercial driving rules.
- Obtain your Commercial Learner's Permit (CLP): After passing the General Knowledge test (and Air Brakes, if applicable), your state DMV will issue you a CLP.
- Pass the Passenger Endorsement Knowledge Test: At your state DMV, complete the 20-question Passenger Endorsement permit test on a computer terminal.
- Pass the CDL Skills Test in a Qualifying Bus: (Critical step) You must use a bus designed to carry 16 or more passengers when taking your CDL skills test — including the pre-trip inspection, backing maneuvers, and on-road driving portions. If you use a standard box truck or semi-truck for your skills test, the P Endorsement will not appear on your license.
- Receive your CDL with the P Endorsement: Once you pass all required tests, you are legally authorized to operate commercial passenger vehicles throughout the United States.
Section 3: Jobs You Can Get with a CDL Passenger Endorsement

| Job Type | Estimated Pay | Key Benefits |
|---|---|---|
| City Transit Bus Driver | $28.00 – $45.00 / hr | Usually a W-2 government position with excellent health insurance and pension or 401(k) benefits. |
| Airport Shuttle / Hotel Shuttle Driver | $22.00 – $35.00 / hr | Fixed routes, lower stress environment, and significant tip income on top of base pay. |
| Charter / Tour Bus Driver | $30.00 – $50.00 / hr | Travel across the country with tour groups; meals and lodging typically covered, plus generous per diem pay. |
| Intercity Bus Driver (e.g., Greyhound, FlixBus) | $60,000 – $100,000+ / yr | Large corporate employers, strict hours-of-service compliance, and strong union protections at many companies. |
Section 4: Passenger (P) vs. School Bus (S) Endorsement — What's the Difference?
Many first-time CDL applicants confuse the Passenger Endorsement with the School Bus Endorsement. In federal law, these are structured as a tiered requirement — you must earn P before you can earn S. The table below breaks it down clearly:
| Comparison | Passenger Endorsement (P) | School Bus Endorsement (S) |
|---|---|---|
| Vehicles Covered | City buses, tour coaches, casino shuttles, church buses | Yellow school buses transporting K–12 students |
| Prerequisites | Only requires passing the General Knowledge test first. | You must already hold the Passenger Endorsement before you can test for the School Bus Endorsement. |
| Test Focus Areas | Luggage safety, pre-trip bus inspection, passenger management on the road | School bus warning light systems, student loading/unloading safety, pedestrian danger zones |
Section 5: CDL Passenger Endorsement Test — Frequently Asked Questions (2026)
Q1: How many questions are on the CDL Passenger test, and what is the passing score?
The Passenger Endorsement knowledge test at most state DMVs consists of 20 multiple-choice questions. The passing score is 80%, which means you can miss no more than 4 questions. You must get at least 16 correct to pass on the spot.
Q2: Do I need to take a separate skills test to get the Passenger Endorsement?
The Passenger endorsement requires passing the Passenger knowledge test. In addition, CDL applicants must complete the CDL skills test in an appropriate passenger vehicle to qualify for unrestricted passenger vehicle operation. However, there is one important condition: you must use a vehicle designed to carry more than 15 passengers when taking your CDL skills test — including the pre-trip inspection, backing exercises, and on-road driving. If you complete your skills test in a non-passenger vehicle, your license will carry a restriction code that prevents you from operating passenger-carrying commercial vehicles.
Q3: If I already have the School Bus (S) Endorsement, can I drive a regular commercial bus?
Absolutely. Because federal law requires you to hold the Passenger Endorsement before testing for the School Bus Endorsement, having the S Endorsement automatically means you already have the P Endorsement. You are legally permitted to operate standard commercial passenger buses.
Q4: How often does the Passenger Endorsement need to be renewed? Do I have to retest?
Unlike the Hazmat endorsement, which requires annual background checks and periodic retesting, the Passenger endorsement does not have an independent renewal cycle. It is tied directly to your base CDL expiration date. When you renew your CDL, your endorsement renews with it — as long as you maintain a current, valid DOT Medical Certificate. No retesting is required at renewal.
