Behnid The wheel training

Drivers who have a class A commercial driver’s license (CDL) usually have to complete a pre-trip inspection on their non-passenger commercial vehicles. Having a pre-trip inspection checklist handy helps driver’s know what to expect when they pass their CDL examination and what parts of their vehicle the will need to inspect before heading out on the road. 

• Brakes and air system.
• Steering mechanism.
• Lights and reflectors.
• Tires, wheels, and rims.
• Windshield wipers.
• Rearview mirrors.
• Emergency equipment.

 When getting a CDL, drivers need to pass a  pre-trip inspection test. It’s more intensive than the inspection drivers perform daily. This pre-trip inspection checklist for a Class A CDL gives drivers an overview of performing an inspection. Check your state’s CDL manual for a complete list of inspection requirements.

 A driver’s first responsibility is to ensure that everything regarding their vehicle is in order. Prior to operating the truck, it is important that you are fully alert and not impaired by anything that may affect your judgement. When approaching the truck, the driver needs to assess the general condition of the truck:  Complete an overall visual inspection of the truck, noting damage, fluid leaks under the truck, and general appearance.  Check to see if the tractor-trailer is leaning to one side or the other.  Confirm that the Vehicle Inspection Program (VIP) certificate/sticker is present and valid and conduct the ‘Under the Hood’ portion of the pre-trip inspection 

 To prevent fall and injury, it is important for drivers to maintain three-point contact when entering and exiting the cab. To enter the cab safely, use the following steps: 1. Always check steps and handles for grease, fuel, oil, mud, and ice. Clean off all residue before entering cab. Keep steps as clean as possible to eliminate slipping and injury. 2. Wear appropriate footwear and high-visibility clothing. 3. Maintain a minimum of three points of contact between your body and call at all times during the entry. Focus on your entry, always facing the tractor, avoiding distractions which may result in injury. 4. Place one foot on the step while keeping the other foot securely on the ground. Grip the handle on the inside of the door with one hand and the handle on the exterior cab frame with the other. Notice the three points of contact – two hands and one foot. 5. Move your lower foot to the top step, pulling your body with your arms if necessary. There are still three points of contact. 6. Bring your rear foot to the top step. Both feet are now on the top step so you may release one handle and still maintain three points of contact. 7. Slide or step into the cab and release the remaining handle, because you are now safely inside.
