Starting CDL training can feel like a big step. While in school, students are learning how to handle large commercial vehicles, understand federal regulations, and prepare for a new career as a professional CDL driver.
But just like any new skill, there are mistakes that can slow down a student’s progress, if they’re not careful.
The good news? Most of them can be avoided if you know what to look for.
Here are the top five mistakes students often make during CDL training — and how to avoid them.
1. Treating CDL School Like Regular School
One of the biggest mistakes students make is thinking CDL training is just like high school or a typical classroom course.
It’s not.
Yes, it does begin with classroom instruction to learn the fundamentals. Trucking school students at NETTTS learn about safety rules, vehicle systems, trip planning, and regulations from the Federal Motor Carrier Safety Administration. But CDL training is also hands-on. Students are also learning how to operate a tractor trailer safely in a real world environment.
Why This Is a Problem
If students:
- Don’t take the classroom part seriously
- Skip studying for the learner’s permit
- Don’t pay attention during safety lessons
Then what? Then students will likely not be successful in pursuing their CDL.
Understanding classroom theory is an important part of learning the rules of the road as a truck driver. Taking the time necessary to understand and learn this material can mean not having to struggle later when it’s time to apply that knowledge behind the wheel.
What to Do Instead
- Show up on time every day
- Take notes during classroom sessions
- Study the CDL manual at home
- Ask questions if something doesn’t make sense
Treat CDL school like job training. Because that’s exactly what it is.
2. Not Practicing Pre-Trip Inspections Enough
The Pre-trip inspection is one of the most important parts of CDL training, and can be one of the most commonly underestimated. Practice and repetition is key.
During the state road test, students are required to demonstrate a pre-trip inspection of their vehicle. If key items are skipped or done incorrectly, the student risks not passing the state CDL exam.
Why This Is a Problem
Some students think:
- “I’m close enough.”
- “I just need to know how to drive.”
- “This part isn’t that important.”
But in reality, pre-trip inspections are about safety. As a commercial driver, truckers are responsible for making sure their truck is safe to operate before it ever hits the road.
What to Do Instead
- Practice the pre-trip inspection often
- Say the steps out loud while practicing
- Break it into sections to memorize one section at a time
- Don’t just memorize but understand why each part matters
When a CDL student understands the purpose behind checking brakes, tires, lights, and air systems, etc. it becomes easier to remember.
3. Letting Nerves Take Over Behind the Wheel
Driving a tractor trailer for the first time can feel intimidating. That’s normal. But another common mistake is letting fear or nerves control performance.
Why This Is a Problem
Feeling too tense can lead to:
- Overcorrection of steering
- Rushing backing maneuvers
- Forgetting to breathe and stay calm
- Skipping or forgetting a step in the process
Confidence is built over time. But it starts with trusting the training process.
What to Do Instead
- Focus on one skill at a time
- Listen carefully to instructor feedback
- Don’t compare yourself to other students
- Take a deep breath before each maneuver
Remember, nobody walks into CDL school knowing how to back a trailer perfectly. That’s what training is for.
4. Ignoring Feedback from Instructors
Instructors at NETTTS are experienced CDL drivers. Many have helped train hundreds, sometimes thousands, of students. When they offer a correction, it’s not criticism, it’s preparation.
As a student, it’s important to learn from this feedback without feeling defensive or brushing it aside.
Why This Is a Problem
Overconfident students may:
- Assume they already know enough
- Repeat the same mistakes
- Don’t adjust technique
These students may have a harder time passing your CDL test.
Instructors are there to help you succeed. They know what examiners look for and what employers expect.
What to Do Instead
- Ask for clarification if you don’t understand the reason behind a correction
- Practice the exact skill they point out
- Keep a small notebook of tips to review later
Being coachable is a valuable trait to have during CDL training, and in a future trucking career.
5. Choosing the Wrong School
This mistake happens before training even starts.
Not all CDL schools are the same. With federal Entry-Level Driver Training requirements in place, it’s important to attend a school that meets all federal standards.
Why This Is a Problem
If a school:
- Doesn’t meet ELDT requirements
- Offers limited behind-the-wheel training
- Doesn’t prepare students for all aspects of the CDL test
- Doesn’t have proper accreditation
- Does not offer Career Services Support
Students may struggle to pass their road test, or lack access to certain opportunities in the trucking industry.
Reputable schools follow strict guidelines and are committed to safety and compliance.
What to Do Instead
Before enrolling, ask:
- Is the school accredited?
- How long will I be able to practice before my road test?
- Are instructors experienced?
- Do they help prepare students for all aspects of the CDL exam?
- Do they offer job placement assistance?
Choosing a school that operates professionally and meets federal standards can make a big difference in long-term success.
Bonus Mistake: Not Thinking About the Future Beyond the Test
Passing your CDL test is important but it’s just the beginning. Some students focus only on “getting the license” instead of preparing for the job itself.
Remember
Truck driving is a career that can require:
- Professionalism
- Strong communication
- Time management
- Safety awareness
Start building those habits during training.
Show up early. Take responsibility. Treat your instructors and classmates with respect. These habits follow you into your first driving job.
CDL Training Is an Investment in Your Future
CDL training may feel like it moves quickly. The weeks can fly by.
Avoiding these common mistakes can help you:
- Feel more confident during training and testing
- Understand what’s expected during the CDL exam
- Be prepared for your first driving job
- Build a strong foundation for your future career
The key is simple: take it seriously, stay focused, and trust the training process.
It takes time to build these skills, and most classmates are in the same situation — learning the basics, practicing backing maneuvers, and working through pre-trip inspections. The right attitude and dedication to training can help line a student up for success.
If you’re considering CDL training, take time to research your options and choose a program that prepares you not just to pass the test, but to succeed on the road.
