About the Texas Pre Trip Inspection Test
Topics Covered
- ✓Air brake system components — Texas examiners check the slack adjusters and air dryer because heat and dust cause more failures here than anywhere else
- ✓Lighting and reflectors — required year-round, but especially critical for night runs on rural two-lanes like US-83 where deer are common
- ✓Tires and wheels — tread depth, sidewall damage, and proper inflation; Texas heat accelerates tire failures faster than northern states

Texas DMV examiners don't care if you can recite the manual word-for-word. They care if you can walk around a real truck and point out defects. When you practice, use the 'TAP' method: Touch, Announce, Pass. Touch each component you inspect, say what you're checking for, and then tell the examiner it's in good condition. If you skip the touch, they'll dock you.
Focus on air brakes more than anything. Texas examiners will ask you to demonstrate a brake check — pump down the pressure, listen for leaks, watch the gauges. They want to see that you understand how the system works, not just that you can name parts. Also, know the difference between a 'major' and 'minor' defect. A cracked brake drum is a major defect — you'd fail the vehicle inspection. A loose mud flap is minor — you'd note it but it won't ground the truck.
One thing Texas examiners love: checking the coupling area. They'll ask you to squat down and look at the fifth wheel's locking mechanism. Make sure you can explain how to verify the jaws are closed around the kingpin. If you're hauling a trailer out of the Port of Houston, that connection is the only thing keeping the trailer attached at 70 mph on I-610.
The Texas DMV (TxDMV) handles CDL skills testing at over 50 locations across the state. You need to schedule an appointment online — walk-ins aren't accepted for CDL skills tests. The fee for the skills test (including pre-trip) is $75, plus a $11 driver license fee if you pass. You'll need to bring your CLP, a valid medical certificate, and the vehicle you plan to use for the test. The vehicle must pass a basic safety inspection before you even start the pre-trip.
Popular testing locations include the Garland Mega Center (I-635 and Jupiter Rd), the Austin North office (N IH-35), and the Houston West office (Gessner Rd). Each location has its own examiners, but the pre-trip test is standardized across the state. Expect a 30-minute time limit for the written portion. The actual hands-on pre-trip inspection during the skills test can take up to 45 minutes — you'll be talking the whole time.
Texas doesn't have a separate pre-trip endorsement test. This written test is part of the General Knowledge or Skills Test prep, depending on your CDL class. Class A drivers need to know both tractor and trailer systems. Class B drivers only inspect the straight truck. If you're taking the test for a school bus endorsement, expect additional items like emergency exits and wheelchair securement.
About the Texas Pre Trip Inspection Test
The Texas Pre Trip Inspection test isn't just a checklist — it's the first thing you do in your CDL skills exam. Texas examiners watch every move you make around the truck. They've seen it all, and they know when you're faking it. This test covers the same 25-question format the Texas DMV uses at every location, from the Garland Mega Center to the El Paso office on Montana Ave.
In Texas, you're driving through some of the harshest conditions in the country. Heat that cracks rubber, dust that clogs air filters, and humidity off the Gulf that rots electrical connections. The pre-trip isn't a formality — it's what keeps you from being the guy on the side of I-45 with a blown steer tire at 3 PM in August. The Texas DMV expects you to know every component that could fail on a long haul from Houston to Dallas.
The test focuses on the vehicle systems that matter most for Texas roads: brakes (especially air brakes), lights and reflectors, tires and wheels, coupling devices, and emergency equipment. You'll need to identify defects that could cause a crash on a downhill grade near Comfort, Texas, or a blowout on the concrete slabs of I-35. The questions are multiple-choice, but they require real knowledge — not just memorization.
You get 30 minutes for 25 questions. That's plenty if you know the material. If you don't, you'll run out of time second-guessing yourself. Use our practice test to find your weak spots before you waste $75 on a DMV appointment.
