The Road Skills CDL Test in Pennsylvania
After an applicant has passed each of the required written CDL exams, he or she will then need to address the road skills CDL test obligations ahead. All CDL road tests will involve a form of pre-trip inspection of the vehicle before getting onto the road, a vehicle control test on a closed course, and finally, a live test on the actual road. Below is a rundown on what to expect from each.
Pre-trip inspection test: During this portion of the commercial driver license test, your examiner will review the interior and exterior of your chosen vehicle to ensure that it is safe to drive. Applicants will be scored based on the scrupulousness of their inspection and explanation of key points. More specifically, the CDL exam asks that drivers check under the hoods or engine compartments, inspect the brakes and other key aspects, and then provide a reason for inspection. Note that if your vehicle has air brakes, then you will also be slotted to complete an air brakes knowledge test.
Basic vehicle control test: The second portion of your road skills CDL test will be to demonstrate your ability to maneuver the vehicle before actually getting on the road. As such, your basic vehicle control test will take place on a closed course with boundaries and space given to conduct an examination of various turns, parking and back-and-forth movements. You will be primarily judged on your ability to stay within the lines. Note that each test will differ based on the layout of the selected test site.
On-road driving test: Your final commercial driver license test will be on the road, and will be comprised of a driving route, as determined by your examiner. Specifically, there will be between three to six exercises your proctor will have you complete, which will involve different traffic situations. These could be railroad crossings and different kinds of roads, highways and intersections. Furthermore, your ability to indicate movements like turns, merges and switches will be measured.
