Tips for I-10 Drivers This Holiday Weekend
California and Arizona pumps will hit your wallet hardest—consider topping off just before crossing into New Mexico or Texas for savings of $1+ per gallon. Texas and Louisiana offer the best values along the corridor, often under $3.70. Florida rebounds toward the national average.
Monitor traffic apps for congestion near major metros like Houston and New Orleans. Combine fuel stops with rest breaks, carry water for desert stretches, and budget extra for premium or diesel if needed (typically $0.50–$1 higher). Safe travels and enjoy the long weekend!
