Always inspect the vehicle:

Inspecting the vehicle before starting your trip is crucial for ensuring safety on the road. This practice allows you to identify any potential issues that could lead to mechanical failures or accidents during your journey. A pre-trip inspection typically includes checking the brakes, tires, lights, and fluid levels, which helps in minimizing risks associated with vehicle breakdowns or unsafe driving conditions. By conducting this check prior to departure, drivers can address any necessary repairs or maintenance issues, thereby enhancing the safety of both the driver and others on the road.

The other choices may suggest maintenance or inspection at scheduled intervals or in response to problems, but they do not emphasize the proactive approach of ensuring safety right before the trip begins. Regular maintenance and periodic checks are important, but the most immediate safety measure is the inspection conducted right before you drive.
