What should be checked before starting a long-haul journey with a trailer?

Before embarking on a long-haul journey with a trailer, it is crucial to check both tire pressure and brakes. Proper tire pressure is essential for safety and fuel efficiency; under-inflated tires can lead to blowouts or poor handling, significantly increasing the risk of accidents. In addition, brakes are vital for ensuring that the truck can stop effectively, especially when dealing with a load. A trailer adds extra weight, which requires a thorough check of the braking system to confirm that it operates correctly and can handle the demands of a long journey.

While checking the fuel level is important, it is not the only thing that ensures a safe trip. Windshield wipers and the navigation system are also important, but they do not directly relate to the operational safety of the vehicle. Focusing on tire pressure and brakes addresses the most critical aspects of vehicle performance and safety prior to a long-haul journey.
