To obtain a Commercial Driver’s License (CDL) in Ohio, you must pass a written exam covering several aspects of commercial driving as well as a hands-on skills test, which includes a pre-trip inspection. All applicants need an advanced understanding of how to safely operate a commercial vehicle in various conditions. This includes the mandatory pre-trip inspection, which is essential for ensuring the safety of your vehicle. If you are interested in driving trucks or buses with air brakes, a basic knowledge of air brake systems is also required.
Why is the pre-trip inspection so important? Federal and state laws, including those in Ohio, require pre-trip inspections of all commercial motor vehicles. The pre-trip inspection is the most effective way for a driver to identify mechanical issues like brake malfunctions, tire defects or problems with the steering system before going on what might be a long trip. Commercial vehicles require regular maintenance, and the pre-trip inspection helps prevent breakdowns before they happen.
The pre-trip inspection involves a walk-around procedure, which you should perform the same way every time to make it easier to remember. When learning about all the checks you must carry out, be sure to memorize them in an organized manner. More details on this procedure can be found in the official Ohio CDL manual, though many online resources are available to enhance your learning journey.
