Regular undercar inspections help prevent which of the following?

Regular undercar inspections are crucial because they allow for the early detection of potential issues such as worn-out components, fluid leaks, or other mechanical failures that can lead to serious breakdowns. By identifying and addressing these problems before they escalate, drivers can significantly reduce the risk of accidents caused by sudden mechanical failures while on the road.

Furthermore, the undercarriage is home to vital systems—including the suspension, brakes, and exhaust—that play a critical role in vehicle safety and performance. Ensuring that these components are in good working order directly impacts the vehicle's overall reliability, helping prevent situations that could result in serious accidents due to inadequate braking or steering capabilities.

Although the other options represent maintenance concerns, they do not directly relate to the primary safety implications associated with undercar inspections as effectively as preventing serious breakdowns and accidents does. Regular inspections primarily focus on safety-related components, making option C the most relevant and significant outcome of such inspections.
