Understanding the Test Structure

The Basic Control Skills Test is divided into four main exercises designed to assess your ability to control your vehicle in tight spaces and to judge its position relative to other objects. You must pass this test before moving on to the Road Test.

Components of the BCS Test:

  1. Forward Stop
  2. Straight-Line Backing
  3. Forward Offset Tracking
  4. Reverse Offset Backing

Each exercise tests specific skills and requires precision and control.



Scoring Criteria for the Basic Control Skills Test

The Basic Control Skills Test evaluates your ability to maneuver a commercial vehicle safely and accurately. The test consists of four exercises, each with specific scoring criteria based on performance in various areas. Points are deducted for pull-ups, encroachments, looks, and improper final positioning. Below is a detailed breakdown of the scoring criteria as outlined in the CDL Handbook.

Pull-ups

Definition:
A pull-up is when you move the vehicle forward during a backing exercise to adjust your position and avoid encroachments.

Scoring:

  • Allowed Pull-ups:
  • Exercise 2 (Straight-Line Backing): 1 free pull-up allowed.
  • Exercise 4 (Reverse Offset Backing): 2 free pull-ups allowed.
  • Penalties:
  • Excessive pull-ups beyond the allowed free pull-ups result in point deductions.
  • Stopping without changing direction is not counted as a pull-up.


Back-ups

Definition:
A back-up occurs when you move the vehicle backward during a forward-moving exercise to reposition yourself.

Scoring:

  • Applicable Exercise:
  • Exercise 3 (Forward Offset Tracking).
  • Penalties:
  • Each back-up during this exercise results in point deductions.
  • No free back-ups are permitted.


Encroachments

Definition:
Encroachments occur when any part of your vehicle (except mirrors or high-mounted unique parts) crosses or touches the exercise boundary lines or cones.

Scoring:

  • Penalties:
  • Each instance of touching or crossing a boundary line results in point deductions.
  • Unique parts above door mirror height (like a bucket truck) do not count as encroachments unless they are below mirror height.


Looks

Definition:
A “look” is when you exit the vehicle to check its position during a backing exercise.

Scoring:

  • Allowed Looks:
  • Exercise 2 (Straight-Line Backing): 1 free look allowed.
  • Exercise 4 (Reverse Offset Backing): 2 free looks allowed.
  • Penalties:
  • Exceeding the allowed looks results in point deductions.
  • Opening the door or moving from a seated position to look outside is also counted as a look.
  • Opening the door while the vehicle is in motion may result in automatic failure.



Final Position

Definition:
Final position evaluates how well you align your vehicle within the designated boundaries at the end of each exercise.

Scoring:

  • Penalties:
  • Points are deducted if your vehicle does not finish within the boundaries or as instructed by the examiner.
  • The vehicle must be straight and fully within the defined area.


Automatic Failures

Certain actions can lead to immediate failure of the test, regardless of the score.

Automatic Failure Criteria:

  • Failure to Follow Instructions:
  • Not complying with the examiner’s directions.
  • Unsafe Acts:
  • Examples include forgetting to set the parking brake, opening the door while in motion, or not maintaining three points of contact when exiting or entering the vehicle.
  • Any action deemed unsafe by the examiner.

Forward Stop:

Modernized Basic Control Skills Test Exercise 1


Objective:

To assess your ability to judge the front end of your vehicle during a controlled stop.


  • Starting Position: Begin before the first set of cones at the alley entrance.

  • Pulling Forward: Move forward carefully and aim to place the frontmost part of your vehicle inside the stop box. You may stop only once.

  • Completing the Maneuver: Once in the stop box:
  • Set the parking brake
  • Shift to neutral
  • Sound your horn to signal to the examiner that you’re finished.

Straight Line Backing:

Modernized Basic Control Skills Test Exercise 2

Objective:

To evaluate your ability to reverse your vehicle in a straight line.

  • Getting into Position:  After completing the forward-stop exercise, pull forward until your vehicle is outside the coned area at the end of the alley.

  • Backing Up:  Carefully back through the 100-foot alley:
  • You’re allowed one get-out-and-look to check your position.
  • You may also use one free pull-up if needed. Additional pull-ups will result in penalty points.

  • Completing the Maneuver:  Once you’ve backed through the alley:
  • Set the parking brake
  • Shift to neutral
  • Sound your horn to signal the examiner that you’re done.

Forward Offset Tracking:

Modernized Basic Control Skills Test Exercise 3

Objective:
To test your ability to maneuver around obstacles while moving forward.


  • Starting Position: Begin behind the cones at the alley entrance.

  • Executing the Maneuver: Pull forward through the alley and steer to the left opening of the opposite lane:
  • Keep the near-most axle of your vehicle within the two-foot mark that is four feet from the frontmost cone as you exit.
  • Important: You cannot back up the vehicle without receiving penalty points. You may not exit the vehicle. 

  • Completing the Maneuver: Position your vehicle parallel with the outer boundary cones. Then:
  • Set the parking brake
  • Shift to neutral
  • Sound your horn to signal the examiner that you’re done.

Reverse Offset Backing:

Modernized Basic Control Skills Test Exercise 4

Objective:
To assess your ability to offset back and park accurately within a confined space.


  • Starting Position: Begin parallel to the outer boundary cones.

  • Executing the Maneuver: Back into the alley you pulled out of during the Forward Offset exercise:
  • You’re allowed only two get-out-and-looks to check your position.
  • You may also use two free pull-ups without penalty. Additional pull-ups will result in point deductions.
  • Ensure the rearmost part of your vehicle ends up in the stop box.

  • Completing the Maneuver: Once in position:
  • Set the parking brake
  • Shift to neutral
  • Sound your horn to signal the examiner that you’re done.

Your Instructors Are Qualified. Can You Prove It?

August 17, 2026
Every certification your school submits to the Training Provider Registry rests on one thing: the instructor who signed off was qualified to do it. That makes instructor qualifications the single highest-stakes file in your building. When a student's record gets questioned, the school defends one certification. When an instructor's qualifications get questioned, every student that instructor ever signed off is in question at the same time. One gap, multiplied by hundreds of graduates. That is why instructor files deserve more attention than they usually get, and why "we know our people are qualified" is a sentence worth retiring. Knowing it and proving it are two different jobs. The second one is the one that counts. What qualified actually means The federal requirements come down to a few things. A behind-the-wheel instructor needs to hold a CDL of the same or higher class, with the endorsements needed for the vehicle they are teaching in, plus at least two years of experience driving that class of vehicle or two years of experience as an instructor. A clean licensing history matters too. An instructor whose CDL has been suspended, revoked, or cancelled in the recent past can be disqualified from teaching, even if their license looks valid today. Then the states add their own layer. Some require instructor licenses, background checks, or their own experience documentation on top of the federal floor. The federal rule is the minimum, and your state decides how much higher the bar sits. A school operating in more than one state can have different qualification requirements for instructors doing the same job. Qualified on paper, provable on demand Here is where schools get caught. The instructor genuinely is qualified. Twenty years behind the wheel, endorsements for everything, sharp as they come. But the file holds a photocopy of a CDL from three renewals ago and nothing else. When someone asks the school to prove the qualification, the proof is a phone call to the instructor asking them to bring their license in. A complete instructor file answers the question before anyone asks it. A current copy of the CDL with the right class and endorsements. Documentation of the experience that qualifies them, whether that is driving history or instructional history. The MVR on file and reviewed. State instructor credentials where they apply. Every requirement, matched to a document, sitting in one place. When an auditor asks, the answer takes minutes instead of a scramble. 

Everyone Knows the Trainer and Examiner Rule. Can You Prove You Followed It?

August 10, 2026
Every school knows the rule: the person who trains a student and the person who tests them have to be two different people. It is one of the oldest lines in third-party testing, and everyone in this industry can recite it. Knowing it happened is different from showing it happened Most schools keep the trainer and examiner separate every single time. The owner would swear to it, and they would be telling the truth. The problem is that swearing to it is all they can do. When the proof of separation lives in people's memory of who was working that day, the school has compliance that evaporates the moment memory fades or staff move on. To an auditor, a rule followed and a rule documented are two different things, and only one of them counts. The test of your documentation is simple. Pull a student file from eighteen months ago. Could a stranger look at that file and identify who trained the student and who examined them, on their own, in under a minute? If the answer requires someone to explain, the record is incomplete. The separation should be visible on the page itself. What the paper trail actually requires Two layers of documentation make the separation provable. The first is the training history. Every training event should name the instructor who delivered it. The person, specifically. A student's file should read like a roster of everyone who worked with them: which instructor ran their range sessions, which one sat with them on the road, on which dates. The complete list of who touched the student's training is the foundation, because proving the examiner was independent starts with a record of everyone who trained the student. The second is the testing record. The skills test should name the examiner just as clearly, tied to the date and the result. Put the two layers side by side and the separation proves itself. The examiner's name is absent from the training history, and the case is closed. Zero explanation, zero reconstruction, zero calls to the scheduler to vouch for who did what.
