What should a driver do prior to embarking on a long road trip as stated in Title 20?

Answer: B — Ensure their vehicle is in good working condition

Before embarking on a long road trip, ensuring that the vehicle is in good working condition is crucial for both safety and performance. A well-maintained vehicle can prevent breakdowns and mishaps that might occur during travel, thereby providing a safer driving experience. This includes checking the engine, brakes, tires, lights, fluid levels, and battery, among other essential components. While checking the GPS system, obtaining a new driving handbook, and joining a roadside assistance program can be helpful in certain contexts, they do not directly address the critical need to ensure that the vehicle itself is ready for the journey. Overall, prioritizing the vehicle's condition is fundamental to a successful and safe trip.
