What is a critical factor to check before a long trip with a commercial vehicle?

Before embarking on a long trip with a commercial vehicle, checking the tire pressure and overall vehicle condition is essential for safety and efficiency. Proper tire pressure is crucial because it directly affects vehicle handling, fuel efficiency, and tire wear. An under-inflated tire can lead to blowouts or accidents, while tires that are over-inflated can also pose safety risks.

In addition to tire pressure, assessing the overall condition of the vehicle ensures that critical systems—such as brakes, lights, and fluid levels—are functioning correctly. This comprehensive check minimizes the risk of breakdowns while on the road and helps ensure compliance with safety regulations, ultimately protecting both the driver and others on the road.

While checking the fuel level is important for planning your trip, it is not as critical a factor as ensuring the safety of the vehicle’s tires and mechanics. Other options, such as the condition of the radio or seat alignment, are less significant in the context of safety and vehicle operability for a long journey.
