Earning your commercial driver’s license (CDL) in Idaho is a crucial step toward a trucking career. The final challenge is the Idaho CDL skills test, a three-part exam administered by Idaho Division of Motor Vehicles (DMV) approved third-party testers. This test evaluates your ability to inspect, maneuver, and safely operate a commercial motor vehicle (CMV) according to Idaho-specific regulations.
At CDL eXpert, we specialize in preparing drivers for the knowledge and skills tests required to obtain a CDL. While we don’t offer behind-the-wheel training, our FMCSA-compliant Entry-Level Driver Training (ELDT) program provides the essential knowledge you need to approach the Idaho CDL skills test with confidence.
This guide explains the structure of the Idaho CDL skills test, state-specific requirements, and how CDL eXpert can help you prepare.
What’s on the Idaho CDL Skills Test?
The Idaho CDL skills test consists of three parts:
Pre-trip vehicle inspection
Basic vehicle control (backing maneuvers)
On-road driving
Each section tests your ability to safely and efficiently operate a commercial vehicle under Idaho DMV guidelines.
Pre-Trip Vehicle Inspection
The pre-trip inspection evaluates your ability to assess your vehicle’s condition before driving. You must inspect key components, explain their function, and identify potential safety issues.
What to Expect
You will inspect critical vehicle components, including:
Engine compartment
Brakes
Tires and wheels
Lights and reflectors
Steering system
Trailer coupling devices (if applicable)
If your vehicle has air brakes, you must perform a full air brake system check, including the air brake leakage test and emergency brake test.
You must verbally explain each part of the inspection using correct terminology such as:
"Properly mounted and secure"
"Not damaged or leaking"
Idaho-Specific Requirements
Idaho CDL pre-trip inspections are pass/fail. Missing critical components results in automatic failure rather than a point deduction.
Air brake tests are required for vehicles equipped with air brakes. Failing to perform the test correctly will immediately disqualify you from an air brake endorsement.
Idaho’s cold climate affects vehicle performance. Examiners emphasize checking brakes, tires, and engine components for issues caused by freezing temperatures.
Idaho DMV provides an official pre-trip inspection checklist that applicants must follow exactly to pass.
Basic Vehicle Control (Backing Maneuvers)
This section evaluates your ability to maneuver the vehicle in a controlled space. You must complete a series of backing and parking maneuvers while staying within boundaries and avoiding obstacles.
What to Expect
Idaho CDL examiners typically test the following maneuvers:
Straight-line backing – Reversing the vehicle in a straight path between two sets of cones.
Offset backing (left or right) – Backing into a space offset from your starting position.
Parallel parking (driver-side or conventional) – Parking the vehicle within a marked boundary.
Alley docking – Backing the vehicle into a simulated dock or parking space at a 90-degree angle.
Idaho-Specific Requirements
Parallel parking is required for all CDL applicants in Idaho. Unlike some states, Idaho mandates this maneuver for all commercial drivers.
Offset backing and alley docking are frequently tested. The exact maneuvers may vary depending on the testing site.
Hitting cones, excessive pull-ups, or crossing boundaries results in deductions. Too many mistakes will cause failure.
Some testing locations may have different maneuver requirements, so applicants should confirm with their test site.
On-Road Driving
The final portion of the test assesses your ability to operate a CMV safely in real traffic conditions. The examiner will evaluate your driving on city streets, highways, and possibly rural or mountainous roads, depending on the testing site.
What to Expect
During the on-road driving test, you will be evaluated on:
Lane positioning and speed control
Proper use of mirrors and signals
Turning, intersections, and right-of-way rules
Shifting gears (for manual transmissions)
Merging onto highways and handling traffic
Railroad crossings, school zones, and work zones
Idaho-Specific Requirements
Idaho CDL road tests often include rural and mountainous roads. Examiners assess how drivers handle steep grades, sharp curves, and winding roads.
Freeway driving is required. You must demonstrate proper merging, maintaining highway speed, and exiting safely.
Winter driving considerations may be tested. Examiners may evaluate how drivers handle wet or icy conditions.
Strict lane change and blind spot rules apply. Examiners watch for proper signaling, mirror use, and checking blind spots before merging or changing lanes.
School zones and work zones are strictly enforced. Speeding or failing to follow posted signs results in automatic failure.
Proper railroad crossing procedures are required. Even if no train is present, failing to stop when required results in immediate failure.
Idaho CDL Testing Locations
The Idaho CDL skills test is only administered at DMV-approved third-party testing centers—Idaho DMV offices do not conduct CDL road tests. Due to high demand, appointments should be scheduled well in advance.
Some of the busiest CDL testing locations in Idaho include:
Boise
Nampa
Twin Falls
Idaho Falls
Pocatello
Scheduling your test early is strongly recommended.
