What is considered the first step to operate safely as a defensive driver?

To operate safely as a defensive driver, conducting a good pre-trip inspection is the first step. This process involves thoroughly checking the vehicle before hitting the road, which is crucial for identifying any potential mechanical issues or safety concerns that could lead to accidents or breakdowns while driving.

By performing a pre-trip inspection, a driver ensures that critical components of the truck, such as brakes, lights, tires, and steering, are functioning correctly, which forms the foundation for safe driving practices. This proactive measure allows drivers to address any problems early on, promoting overall safety for themselves, their cargo, and other road users.

Other options, such as checking fuel levels or planning the route in advance, contribute to safe driving but are secondary to ensuring that the vehicle itself is safe and roadworthy. A thorough post-trip inspection is also essential for maintaining standards and reporting any issues after the trip, but it does not precede the act of driving like the pre-trip inspection does. Thus, beginning with a good pre-trip inspection sets the stage for a safer driving experience right from the start.
