What to Do Before Taking Your Car on a Long Road Trip

Inspect and Top Off All Fluids

Before hitting the road, ensure your car’s vital fluids are at optimal levels. Check the engine oil, coolant, brake fluid, transmission fluid, and windshield washer fluid.

Low or dirty fluids can lead to overheating, poor braking, transmission issues, or impaired visibility—especially over long distances. Consult your owner’s manual for recommended fluid types and levels, and top off or replace as necessary. This proactive step helps prevent unexpected breakdowns and keeps your car running smoothly throughout your trip. For a detailed guide, visit Cars.com: How to Check Your Car’s Fluid Levels.

Check Tire Pressure and Tread

Proper tire maintenance is crucial for a safe and efficient road trip. Use a tire pressure gauge to ensure all tires, including the spare, are inflated to the manufacturer’s recommended PSI—found in your owner’s manual or driver’s door jamb.

Inspect tread depth using the penny test: insert a penny into the tread with Lincoln’s head upside down; if you see the top of his head, it’s time for new tires. Proper tire care improves handling and fuel efficiency and reduces the risk of blowouts. For more tips, refer to NHTSA’s Tire Safety Guide.

Test the Battery and Electrical System

A dependable battery and electrical system are essential for a trouble-free road trip. Check your battery’s charge with a voltmeter or have it tested at an auto parts store. Inspect the terminals for corrosion and clean them if needed.

Test all lights—headlights, brake lights, turn signals, and hazard lights—to ensure they’re working correctly. Reliable power is crucial for starting your car, powering electronics, and ensuring visibility. Don’t risk getting stranded with a dead battery or malfunctioning lights.

Examine Brakes and Brake Pads

For safe long-distance travel, inspect your brakes thoroughly. Check the thickness of your brake pads—most should be at least 1/4 inch thick. Listen for warning signs like squealing, grinding, or a soft brake pedal, which may indicate worn pads or other issues.

If you’re unsure about their condition, have a mechanic perform a professional inspection. Well-maintained brakes are vital for responsive stopping and avoiding accidents, especially when driving for extended periods or in unfamiliar terrain.

Ensure All Lights and Signals Work

Before your trip, thoroughly inspect all exterior lights, including headlights, brake lights, turn signals, and hazard lights. Ask a friend to help confirm the rear lights are functioning, or use a reflective surface to check yourself.

Proper lighting is essential for visibility and communication with other drivers—especially at night or in poor weather conditions. Replace any burnt-out bulbs and clean lenses for maximum brightness. Safe, visible lighting reduces the risk of accidents and keeps you compliant with traffic laws.

Pack an Emergency Kit

Being prepared for the unexpected is vital on any long road trip. Pack an emergency kit that includes jumper cables, a flashlight with extra batteries, a first aid kit, bottled water, non-perishable snacks, and basic tools such as a wrench and screwdriver.

Include a tire inflator, reflective triangles, and a blanket for additional safety and comfort. These essentials can help you handle minor breakdowns, injuries, or delays until help arrives. Proper preparation ensures peace of mind and greater safety on your journey. For a complete checklist, visit NHTSA Road Trip Checklist.

Review and Update Registration and Insurance

Before departing, make sure your vehicle registration and insurance documents are up to date and easily accessible in your glove compartment. Expired paperwork can lead to fines or complications if you’re stopped by law enforcement or involved in an accident.

Double-check your insurance coverage for roadside assistance and out-of-state travel, and consider printing a copy of your policy for backup. Having current documents ensures compliance with the law and streamlines the process if you need to file a claim or prove ownership.

Plan Your Route and Stops

Mapping out your route before you leave helps prevent last-minute stress and surprises. Use navigation apps like Google Maps or Waze to chart your course, identify fuel stations, and schedule regular rest breaks every two to three hours. Research alternative routes in case of road closures or heavy traffic. Plan stops near restaurants, scenic spots, or parks to make your journey more enjoyable. Thoughtful planning keeps you refreshed and prepared, reducing fatigue and ensuring a smoother trip. For planning tools, check out Roadtrippers.
