Imagine hitting the road with a flat tire you didn't even notice. Yikes! That's why vehicle inspections are super important for commercial drivers. Unlike cars, CMVs undergo intense stress, and tiny issues can quickly become major safety hazards. A proper inspection is like a superpower that helps you spot trouble before it starts.

Why Inspect Your Vehicle?

Regular inspections aren't just a good idea; they're the law! The Federal Motor Carrier Safety Regulations (FMCSRs) require drivers to inspect their vehicles. The main goals are to:

• Prevent Accidents: Catching a worn tire, a leaky hose, or a faulty light can prevent a serious crash.
• Ensure Safety: Make sure your vehicle is safe for you, your cargo, and everyone else on the road.
• Avoid Fines: Skipping inspections can lead to hefty fines and even being placed Out-Of-Service (OOS).

Types of Inspections

There are three main types of inspections you'll perform:

Pre-Trip Inspection

This is your most important daily check! Before you even start the engine, you'll walk around your vehicle, checking everything from top to bottom. Think of it as a detailed health check for your truck or bus. You'll check things like:

• Tires: Are they properly inflated? Any cuts or bulges? Are lug nuts tight?
• Lights: Headlights, brake lights, turn signals, clearance lights – do they all work?
• Brakes: Air pressure, brake pads, hoses – no leaks, no worn parts?
• Fluids: Oil, coolant, power steering fluid – are levels correct? No leaks under the vehicle?
• Suspension: Springs, shocks, U-bolts – no broken or cracked components?
• Coupling Devices: If you're driving a combination vehicle, is the fifth wheel or hitch secure?
• Safety Equipment: Fire extinguisher, spare fuses, warning triangles – are they present and accessible?

En Route Inspection (During Trip)

While you're driving, you'll constantly be doing mini-inspections. This means keeping an eye on your gauges (air pressure, oil pressure, temperature), listening for unusual noises, and feeling for vibrations. Whenever you stop (like for fuel or a meal), you should do a quick walk-around to check tires, cargo securement, and lights again.

Post-Trip Inspection

At the end of your driving day, you'll do another walk-around. This is where you identify any issues that might have developed during your trip. You'll then complete a Driver's Vehicle Inspection Report (DVIR), noting any defects. If you find a defect that affects safety, you must report it, and the vehicle can't be driven until it's fixed.
