Which fluid levels should be checked during a pre-trip inspection?

During a pre-trip inspection, it is essential to check various fluid levels to ensure the safe and efficient operation of the vehicle. All of the listed fluids—transmission fluid, brake fluid, and windshield washer fluid—play critical roles in vehicle performance and safety.

Transmission fluid is vital for the proper operation of the vehicle's transmission system. It lubricates the moving parts, helps to cool the transmission, and facilitates smooth shifting. Low levels of transmission fluid can lead to overheating or transmission failure.

Brake fluid is crucial for the braking system. It transfers the force from the brake pedal to the brake components, allowing for effective stopping power. Insufficient brake fluid can result in decreased braking performance and could potentially lead to brake failure, posing a serious safety risk.

Windshield washer fluid is important for visibility. It helps to clear dirt, grime, and other obstructions from the windshield, ensuring that the driver has a clear view of the road. Running low on washer fluid could hinder visibility, especially in adverse weather conditions.

Checking all of these fluid levels is a standard part of a thorough pre-trip inspection. It helps in identifying any potential issues before hitting the road and contributes to overall vehicle safety and reliability.
