A proper pre-trip inspection can prevent 90% of roadside emergencies. Whether you're planning a cross-country adventure or a weekend getaway, this 15-point checklist will ensure your vehicle is ready for the road.
Under the Hood
1. Engine Oil
- Check level: Oil should be between the min/max marks
- Check color: Dark oil needs changing
- Check for leaks: Look for oil spots under the vehicle
2. Coolant/Antifreeze
- Check level: Should be visible in the overflow tank
- Check condition: Clean, not rusty or contaminated
- Check hoses: Look for cracks, bulges, or soft spots
3. Brake Fluid
- Check level: Should be near the "max" line
- Check color: Should be clear, not dark or cloudy
- Check for leaks: Look around brake lines and master cylinder
4. Power Steering Fluid
- Check level: Should be between min/max marks
- Check condition: Should be clean and not foamy
- Check for leaks: Look around the power steering pump
5. Windshield Washer Fluid
- Fill reservoir: Use appropriate fluid for the season
- Test sprayers: Ensure they work on all settings
- Check for clogs: Clean nozzles if needed
Tires and Wheels
6. Tire Pressure
- Check all tires: Including spare
- Use proper gauge: Don't rely on visual inspection
- Check when cold: Before driving for accurate readings
- Adjust for load: Add pressure if carrying heavy cargo
7. Tire Tread Depth
- Use penny test: Insert penny head-first into tread
- Check multiple spots: Tread wear can be uneven
- Look for damage: Cracks, bulges, or embedded objects
- Check sidewalls: Look for cuts or abrasions
8. Wheel Alignment
- Check for pulling: Vehicle should drive straight
- Look for uneven wear: Feathering or cupping patterns
- Check steering wheel: Should be centered when driving straight
9. Lug Nuts
- Check tightness: Use a torque wrench if possible
- Look for damage: Stripped or missing lug nuts
- Check wheel covers: Ensure they're secure
Lights and Electrical
10. Headlights
- Test high and low beams: Both should work
- Check alignment: Lights should illuminate road properly
- Clean lenses: Dirty headlights reduce visibility
- Check for cracks: Replace damaged lenses
11. Turn Signals and Brake Lights
- Test all signals: Front, rear, and side markers
- Check brake lights: All should illuminate when braking
- Test hazard lights: Should work independently
- Check for burned bulbs: Replace as needed
12. Interior Lights

Safety Systems
13. Brakes

15. Emergency Equipment
- Check spare tire: Should be properly inflated
- Test jack and tools: Ensure they work and are accessible
- Check emergency kit: First aid, flares, jumper cables
- Test phone charger: Ensure you can charge devices
Seasonal Considerations
Summer Preparation
- Check air conditioning: Test all settings and temperatures
- Inspect cooling system: Ensure radiator and fans work
- Check tire pressure: Heat causes pressure to increase
- Test battery: Heat can accelerate battery failure
Winter Preparation
- Check antifreeze strength: Should protect to expected low temperature
- Inspect wiper blades: Replace if cracked or worn
- Test heater and defroster: Ensure all settings work
- Check battery: Cold weather reduces battery capacity
When to Skip the Trip
Red Flags
- Warning lights on: Don't ignore dashboard warnings
- Unusual noises: Grinding, squealing, or knocking sounds
- Fluid leaks: Any visible fluid under the vehicle
- Steering problems: Difficulty turning or controlling vehicle
- Brake issues: Spongy pedal or grinding sounds
Emergency Situations
- Overheating: Don't drive if temperature gauge is in red
- Smoke or fire: Pull over immediately and call for help
- Loss of power: Don't continue driving if engine is struggling
- Tire failure: Don't drive on damaged or flat tires
Professional Inspection
When to Get Help
- Annual inspection: Have a mechanic check everything yearly

- Preventive maintenance: Ask what should be done soon
Building Good Habits
Daily Checks
- Visual inspection: Walk around vehicle before driving
- Listen for changes: Pay attention to new or unusual sounds
- Check gauges: Monitor temperature, oil pressure, and fuel
- Test brakes: Ensure they feel normal
Weekly Checks
- Tire pressure: Check all tires including spare
- Fluid levels: Quick check of oil, coolant, and washer fluid
- Lights: Test headlights, brake lights, and turn signals
- Cleanliness: Keep windows and mirrors clean
The Bottom Line
A proper pre-trip inspection takes 15-20 minutes but can save you hours of frustration and potentially thousands of dollars in repairs. It's not just about preventing breakdowns—it's about ensuring your safety and the safety of your passengers.
