What action will help prevent a fire?

• A. Carrying a properly charged fire extinguisher
• B. Regularly checking tire pressure
• C. Filling the fuel tank to the brim
• D. Driving with high engine RPMs

Answer: (A)

Carrying a properly charged fire extinguisher reduces the chance that a small fire will get out of control. In a big truck, fires can start from fuel leaks, electrical faults, or overheated parts, and having an extinguisher within reach allows you to quickly suppress flames before they spread. Regular checks of the extinguisher—making sure the gauge shows it’s charged, the pin is intact, and the unit isn’t damaged—keep it ready to work when needed. The other options don’t directly prevent fires: keeping tires properly inflated mainly reduces blowouts, filling the fuel tank to the brim raises fuel vapor and spill risk, and driving with high engine RPMs can increase heat but isn’t a direct fire-prevention measure.
