Delaware Defensive Driving Practice Test

Which of the following is a common rule for thorough vehicle inspections?

1. Always inspect only the tires

2. Check all lights and signals

3. Inspect the engine only

4. Perform checks as needed

The correct answer is: Check all lights and signals

Checking all lights and signals is essential because they play a critical role in ensuring safe communication with other drivers on the road. Properly functioning lights and signals help indicate your intentions, such as turning or braking, which can significantly reduce the risk of accidents. Additionally, malfunctioning lights can lead to traffic violations and increased hazards, especially in low visibility conditions. Incorporating a comprehensive approach during vehicle inspections means paying attention to multiple aspects of the vehicle, not just focusing on one area like the tires or engine. A thorough inspection includes checking lights, signals, brakes, tires, fluids, and other vital components to ensure the vehicle is operating safely and efficiently. While other options suggest limited or conditional checks, they do not provide a holistic approach to vehicle safety, which is crucial for defensive driving and preventing accidents.
