About the Utah CDL School Bus Exam
The Utah CDL School Bus knowledge test is a 20-question examination administered by the Utah Driver License Division (DLD) for commercial drivers who transport pre-primary, primary, or secondary students in a school bus. The S endorsement also requires the separate 20-question Passenger knowledge test. Testing is conducted in English only; translation materials are strictly prohibited. Utah applicants must be at least 21 years old. The School Bus test covers Section 10 of the Utah CDL Handbook: danger zones, mirrors, student loading and unloading, evacuation, railroad crossings under Utah Code § 41-6a-1203, and warning signals under Utah Code § 41-6a-1302. Independent OpenExamPrep practice offers four-option questions on those topics and does not replace ELDT, employer training, or hands-on skills practice.
Exam sponsor: Utah Department of Public Safety (DPS) Driver License Division (DLD). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Utah CDL School Bus: Suggested Study Strategy
Frequently Asked Questions
What is the minimum age to drive a school bus in Utah?
Under Utah Driver License Division rules and Utah Code § 53-3-404, drivers under 21 years of age are restricted to intrastate general commercial driving and are NOT eligible for School Bus, Passenger, or Hazardous Materials endorsements. You must be at least 21 years old to obtain a School Bus endorsement in Utah.
Do I also need a Passenger endorsement to get a School Bus endorsement?
Yes. Under federal regulation 49 CFR 383.123 and Utah DLD rules, any driver seeking a School Bus (S) endorsement must also qualify for and obtain the Passenger (P) endorsement by passing its knowledge and skills tests.
What is the passing score for the Utah CDL School Bus knowledge test?
The test consists of 20 multiple-choice questions. Under Utah DLD rules and 49 CFR 383.135, you must achieve a score of at least 80% (answering at least 16 questions correctly) to pass. Utah DLD does not publish an official time limit.
What does Utah Code § 41-6a-1302 require when school bus lights are flashing?
Utah Code § 41-6a-1302 mandates that motorists approaching a school bus displaying flashing amber lights must slow down and proceed with caution at no more than 20 mph. When flashing red lights and the stop arm are displayed, motorists must stop immediately, unless traveling in the opposite direction on a divided highway, at an intersection controlled by a traffic officer/signal, or on a road with 5 or more lanes.
Where are the primary danger zones around a school bus?
The primary danger zones extend up to 30 feet directly in front of the front bumper (the first 10 feet being the most dangerous), 10 feet along the left side, 10 feet along the right side (where student boarding takes place), and 10 feet directly behind the rear bumper.
What are the railroad grade crossing stop rules for school buses in Utah?
Under Utah Code §§ 41-6a-1203 and 41-6a-1205, school bus drivers must stop within 50 feet but no closer than 15 feet from the nearest rail, quiet the bus, open the driver window and service door, look and listen in both directions, and cross without manually shifting gears. If a signal appears to be malfunctioning, drivers must follow strict verification and dispatch protocols before proceeding.
How much does the School Bus endorsement cost in Utah?
Utah DLD charges $52.00 for the CDL application with written knowledge tests and $18.00 for the School Bus endorsement, which requires both Passenger and School Bus knowledge tests. Two additional endorsement-test attempts cost $9.00. A DLD commercial skills test costs $78.00 for two attempts; third-party testers set their own fees.
Are these practice questions official Utah DLD exam items?
No. These are independent educational study questions based on the Utah CDL Handbook, Utah Code, and federal FMCSA regulations. They do not duplicate official exam items or replace mandatory ELDT training.
