What should you check before embarking on a long journey?

Tyre tread depth
Oil level
Coolant temperature
Brake fluid level

The correct answer is: Oil level

Before starting a long journey, it is crucial to check the oil level in your vehicle. Oil is essential for lubricating the engine components, and having the correct oil level ensures that your engine runs smoothly and efficiently. Insufficient oil can lead to increased friction, overheating, and ultimately catastrophic engine failure, which could leave you stranded or result in costly repairs during your trip. While other checks are also important for a safe journey, such as tyre tread depth, coolant temperature, and brake fluid level, maintaining an adequate oil level is fundamental to the engine's health. Without proper lubrication, the engine may not function optimally, affecting overall vehicle performance and safety. Regularly checking and maintaining oil levels is part of good vehicle maintenance and crucial for long-distance travel reliability.
