Florida CDL Endorsements: Expand Your Driving Career

An endorsement on your CDL allows you to haul specialized cargo or passengers. The following endorsements can be added to Class A, B, or C licenses.

| Endorsement | Code | What It Allows | Test Required |

Placarded Hazmat | H | Transport hazardous materials that require placards | Written exam + TSA background check |

| Tank Vehicles | N | Drive vehicles that transport liquids or gases in bulk tanks | Written exam |

| Passenger | P | Drive vehicles designed to carry 16 or more passengers (including driver) | Written + skills test in a passenger vehicle |

| School Bus | S | Transport pre primary, primary, or secondary school students | Written + skills test; must also have P endorsement |

| Doubles/Triples | T | Pull double or triple trailers | Written exam; Triple trailers are NOT allowed on Florida roads |

| Hazmat + Tank Combo | X | Combination of H and N endorsements | Written exams for both, plus TSA check for hazmat |

## Hazmat Endorsement: Extra Steps Required

Because of federal security rules, the H endorsement requires:

1. Passing the written hazmat knowledge test.

2. Completing a Transportation Security Administration (TSA) security threat assessment (fingerprinting and background check).

3. Paying the TSA fee (currently around $86.50).

Once approved, your hazmat endorsement is valid for 5 years, but the background check must be renewed periodically.

## Passenger & School Bus

- The Passenger (P) endorsement requires a skills test in a passenger rated vehicle . If you’re also getting a School Bus (S) endorsement, you must take an additional skills test in a school bus.

- School bus drivers in Florida must hold both S and P endorsements.

> 🚛 Tip: Adding endorsements early opens more job opportunities; many carriers require a Tanker (N) or Doubles/Triples (T) before hiring.
