Regularly checking tire pressure, oil levels, and brakes is critical for safe vehicle operation. Each of these components plays a vital role in ensuring that the vehicle functions properly and safely on the road.

Tire pressure affects traction, fuel efficiency, and the overall ability of the vehicle to handle road conditions. Under-inflated or over-inflated tires can lead to blowouts or loss of control. Therefore, maintaining the correct tire pressure is essential for safe driving.

Oil levels are crucial for engine health, as oil lubricates moving parts, reduces friction, and helps dissipate heat. Low oil levels can cause severe engine damage, leading to costly repairs or unsafe driving conditions.

Brakes are one of the most critical safety features of any vehicle. Regular checks ensure that the braking system is functioning correctly, preventing potential accidents due to failure to stop effectively.

While windshield wipers and lights are also important for visibility and safety, as well as maintaining bodywork for aesthetic purposes, the components discussed in the correct answer directly affect the vehicle's operational safety and performance on the road, making them a priority for regular checks.
