Road safety is a big concern in many industries that require their employees to drive vehicles on the job. While 94% of serious traffic accidents are the result of human error, these numbers still leave 6% of other, often times avoidable causes, such as faulty systems or broken parts. Drivers can contribute to safer roads by conducting a thorough pre-trip inspection before they head out on a journey. Learn how a pre-trip inspection should be completed with ToolSense, what a pre-trip inspection is, what it entails, and how you can ensure that your employees follow the CDL pre-trip inspection checklist with the help of modern tools.
- A thorough pre-trip inspection should be done on any vehicle before it hits the road.
- This ensures that the vehicle is in working order, increases the driver’s safety, and lowers maintenance costs in the long run.
- Depending on whether a driver is checking a CDL Class A, B, or C vehicle, different components of the vehicle need to be checked before every trip.
- Examples from a pre-trip inspection checklist might include suspension parts, coupling, brakes, wheels, emergency equipment, lights, and windshield wipers.
- Pre-trip inspection software offers checklists and the ability to create custom forms to ensure drivers don’t forget a single detail during the pre-trip checks.
What Is a Pre-trip Inspection?
Any vehicle should be thoroughly checked before it hits the road in what is called a pre-trip inspection. This inspection ensures that the car, truck, or another type of vehicle is in working order to prevent expensive repairs as well as traffic accidents. Essentially, pre-trip inspections keep drivers safe by preventing accidents. They also contribute to lower maintenance costs as flaws can be repaired before they can cause further, more extensive damage. Potential malfunctions, failures, or broken parts are discovered during these checks and can be repaired or replaced before the vehicle heads out on the road. Pre-trip inspections have to be undertaken for trucks as well as their trailers and other vehicles that are being used on public roads, such as tractors.
Driving vehicles commercially requires a specific license which, in the United States, is called a CDL (Commercial Driver’s License). Other countries, such as the UK, Australia, and New Zealand, also require commercial drivers to have a specific license. The minimum age for acquiring a CDL is 18 years in the US. However, in interstate commerce, in the state of Hawaii, or when transporting hazardous materials, drivers are required to be at least 21 years of age. The CDL divides the license into three different classes, which all require different CDL pre-trip inspections.
ToolSense is trusted by 700+ companies
Class A Pre-trip Inspection
CDL Class A includes a combination of vehicles with a gross vehicle weight rating (GVWR) of 26,000 pounds if the towed vehicle weighs over 10,000 pounds. This includes tractor and trailer combinations, truck and trailer combinations, double and triple trailers, livestock carriers, tractor-trailer buses, flatbed trucks, and any vehicle that falls under Class B and C. A Class A pre-trip inspection is necessary for all vehicles that fall under this category.
Class B Pre-trip Inspection
CDL Class B includes vehicles with a GVWR of over 26,000 pounds and vehicles towing a trailer of up to 10,000 pounds. This includes straight and box trucks, such as delivery vehicles, large buses, and trucks with small trailers. A driver with a CDL Class B can also drive Class C vehicles. A pre-trip inspection for Class B vehicles is also necessary. A Class B pre-trip inspection is necessary for all vehicles that fall under this category.
Class C Pre-trip Inspection
A CDL Class C allows drivers to operate any vehicle that transports 16 or more passengers, driver included. According to the Hazardous Materials Transportation Acts, a driver with a Class C license is allowed to operate vehicles designed for the transportation of hazardous materials. This includes small HAZMAT vehicles and passenger vans.
Minimum Pre-trip Inspection Requirements
These classes have different pre-trip inspection requirements, depending on what type of vehicle is being checked and what they are carrying. A pre-trip inspection checklist can help drivers remember which components need to be checked specifically, depending on the type of vehicle. However, these are the minimum requirements during a pre-trip inspection:
Service Brake, Including Trailer Brake Connections
The brake systems for both the towing vehicle and the trailer need to be inspected to ensure that the systems are in working order. If undetected, a malfunctioning brake poses a significant hazard. The brake hose should be securely mounted on both ends and not be leaking air. Any cracks, splits, or cuts indicate that the brake hose needs to be replaced or repaired. The brake chamber should also not be leaking air. Slack adjusters and push rods need to be examined during the pre-trip inspection to ensure that push rods have less than 1 inch of play and stay at a 90-degree angle to the brake chamber. The brake pads should not show signs of oil or debris and have a minimum brake pad thickness of 1/4 inch.
Drivers should insure the parking brakes of both the vehicle and the trailer are in working order by setting the brake and releasing it.
The steering gearbox, air lines and hoses should show no damage or leaks. The hoses should be connected on both sides. The steering shaft should be straight and intact. The rubber on the drag link is properly greased and shows no splits or cuts. During the pre-trip inspection, drivers should make sure that all pins and bolts on the pitman’s arm are secure. According to the Class A pre-trip inspection checklist, tie rods should be secure and show no signs of being bent or broken. The steering wheel should be firmly attached to the steering column.

Lighting Devices and Reflectors
Every pre-trip inspection checklist should include lights and reflectors, meaning these need to be checked by the driver before every trip to make sure they are intact and working. The following lights and reflectors should be inspected before a vehicle hits the road:
- Running lights
- High and low beams
- Turn signals
- Hazard and warning lights
- Brake lights
- License plate lights
Tires and Rims
Before the vehicle is used, drivers should make sure that no unauthorized wheel rims are used. Tires should not show cuts, abrasions, or bulges. The minimum tread depth is 1.6 mm and tires should be evenly worn. Air pressure levels should also be checked, and drivers should make sure that the valve stem is securely in place and not leaking air. Lug nuts should not show rust or cracks. When the driver checks the axle seal, it should be secure and show no leaks.
The functionality of the horn should be checked in every pre-trip inspection to ensure that it works in emergencies.
As trivial as windshield wipers may seem, they are a part of every Class A pre-trip inspection checklist. Drivers must ensure wipers and fluid supply are working. The windshield wiper fluid should also be refilled.

No CDL pre-trip inspection cheat sheet is complete without the mention of rearview mirrors. All of them should be intact and clean without cracks or damage. Drivers should also ensure that they are properly aligned.
When the vehicle is coupled to a trailer, the truck pre-inspection needs to include coupling devices. Air connectors need to be connected on both ends and show no signs of tangling, dragging, or damage. The same goes for the electrical lines, and the safety latch should be in place. The fifth-wheel platform is not allowed to have unauthorized welds and should not show cracks or signs of damage. Drivers should inspect the glad hands to check that the seals are in good condition and not leaking air. Mounting bolts should be tightly in place. The skid plate needs to be properly greased, and the release arm secure in a fully locked position. The kingpin should be firm and secure as well, while showing no cracks or damage. The locking jaw is intact and locks securely around the kingpin. The apron is also mounted and secured with no signs of cracks. The sliding fifth-wheel locking pins need to be in a fully locked position.
Every pre-trip inspection list should include safety and emergency equipment. That means drivers need to ensure that the truck is carrying a functioning fire extinguisher, spare electrical fuses, and reflective triangles.
