What important checks should you perform on your vehicle before a road trip?

• Make sure the radio is working and that you have an adequate supply of snacks.
• Check the fuel, water and oil levels, tire pressure, and ensure the spare tire is in good condition.
  Explanation:

  "Before leaving on a trip, check your car's gasoline gauge and get fuel if you do not have enough for your trip. Check for water and oil needs. There are no service stations located directly on freeways."
• Verify that all interior lights are functioning and that the seats are comfortable.
• Ensure the paint is polished and that there are no scratches on the car's exterior.
