Question 1 of 25Score 0
Why use the same pre-trip sequence each time?
Answer: It reduces the chance of missing a safety item
A consistent pattern helps the driver cover every critical system instead of checking at random. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — routine
What transmission position should be used before starting?
Answer: Neutral, or Park when available
The vehicle should be secured against movement before the engine starts and gauges are checked. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — startup
What should be checked on visible coolant hoses?
Answer: Leaks, damage, and secure connections
Damaged or loose cooling-system hoses can leak, overheat the engine, or fail during travel. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — coolant
What should be checked on power-steering hoses?
Answer: Leaks, damage, and secure mounting
A leaking or damaged steering line can reduce assistance and vehicle control. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — steering
What should be checked on shock absorbers?
Answer: Secure mounting and signs of leakage or damage
Loose, leaking, or damaged shocks can reduce control of suspension movement. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — shocks
What should be checked on brake hoses and lines?
Answer: Leaks, cuts, rubbing, and secure connections
Damaged or leaking brake lines can reduce braking force or fail under pressure. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — brake lines
What should wheel rims be checked for?
Answer: Cracks, bends, and unauthorized welding repairs
A damaged or improperly repaired rim can fail under load or lose the tire. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — rims
What should be checked on wheel hubs?
Answer: Leaks and proper lubricant level where visible
Loss of hub lubricant can damage bearings and lead to wheel or axle failure. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — hubs
What should be checked between dual tires?
Answer: Adequate spacing and no trapped objects
Rubbing tires or lodged debris can damage sidewalls and cause heat buildup. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — duals
What should be checked on lights and reflectors?
Answer: Correct color, cleanliness, condition, and operation
Lighting and reflective devices communicate vehicle position and intentions to others. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — lighting
Why inspect exhaust components for leaks?
Answer: Fumes can enter the cab and create a serious health hazard
Loose or leaking exhaust parts can expose occupants to fumes and create heat or fire risk. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — exhaust
How quickly should oil pressure normally rise after startup?
Answer: Within seconds
Failure to develop oil pressure promptly can damage the engine and requires attention. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — oil pressure
What does an ammeter or voltmeter monitor?
Answer: The charging system
The charging indicator can reveal alternator or electrical-system trouble. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — charging
What should be checked about the windshield?
Answer: It is clean, secure, and free of vision-blocking damage
Clear lawful glass is necessary for detecting traffic, signs, and hazards. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — windshield
How should mirrors be prepared?
Answer: Clean, secure, and adjusted for the best view
Correct mirrors are essential for turns, lane changes, backing, and traffic checks. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — mirrors
What should be checked on the horn?
Answer: It operates and can be heard
The horn is a warning device used to alert others when a hazard develops. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — horn
How is a hydraulic-brake pedal-pressure check commonly performed?
Answer: Pump the brake pedal three times, then hold it for five seconds and verify the pedal does not continue to depress
A standard hydraulic-brake check pumps the pedal three times and then holds firm pressure for five seconds. The pedal should not continue moving down while pressure is held. Study: Texas CDL Handbook — Vehicle Inspection
What if the vehicle pulls strongly during the brake test?
Answer: Stop and have the problem investigated before normal operation
Pulling can indicate unequal braking or another defect that compromises control. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — brake defects
What should be checked on doors and cargo latches?
Answer: They close and secure correctly
Secure closures prevent cargo loss and uncontrolled door movement. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — doors
What should be checked about the fifth-wheel release arm?
Answer: It is locked and properly secured
A release arm left open can allow the coupling to unlock. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — release arm
What must happen when an unsafe condition is found?
Answer: It must be corrected before driving
Inspection exists to find defects before a breakdown or collision, so unsafe conditions require correction. Study: Texas CDL Handbook — Section 2: Vehicle Inspection — defect correction
What aid does Texas DPS provide as part of its modernized CDL Vehicle Inspection testing process?
Answer: A checklist to aid the applicant during the Vehicle Inspection test
Texas DPS describes a checklist as part of its modernized Vehicle Inspection testing process. Applicants still must know how to identify and explain the required safety items. Study: Texas DPS — How to Apply for a CDL
During the CDL Vehicle Inspection test, what should an applicant be prepared to do?
Answer: Identify required components and explain the safety condition being checked
The vehicle inspection is designed to show that the applicant can recognize important components and determine whether they are safe. Hands-on practice is essential. Study: Texas CDL Handbook — Vehicle Inspection
What should be checked about air and electrical connections on a combination vehicle during inspection?
Answer: They are secure, properly connected, undamaged, and routed so they will not chafe, pinch, or drag
Air and electrical connections must remain secure and protected from damage. Poor connections or routing can cause brake, lighting, or control failures. Study: Texas CDL Handbook — Vehicle Inspection
What are the three major portions of the Texas CDL skills test?
Answer: Vehicle Inspection, Basic Vehicle Control, and Road Test
Texas DPS lists Vehicle Inspection, Basic Vehicle Control, and the Road Test as the three major skills-test portions. Applicants should prepare for each using the current Texas testing guidance. Study: Texas DPS — How to Apply for a CDL
