What must be checked on vehicles before any operation?

Prior to any operation of vehicles, checking tire pressure and condition is critical for ensuring safe and efficient performance. Proper tire pressure is essential for optimal handling, fuel efficiency, and tire longevity. Under-inflated or over-inflated tires can lead to poor traction, increased tire wear, and in severe cases, tire blowouts. Additionally, the overall condition of the tires, including tread depth and any visible damage, is vital for maintaining safe driving standards, particularly in varied weather conditions and terrain. Ensuring that tires are in good working order is foundational to vehicle operation and directly affects both safety and operational effectiveness.
