Introduction

PHOTO

Gear up for the celebration of 55 mph Speed Limit Day on January 2! This day commemorates the date when the US Congress passed a law in 1974 that set the maximum speed limit at 55 mph. The law was put in place to reduce fuel consumption and conserve energy, but it also helped make roads safer for drivers and pedestrians. It's been almost five decades since this speed limit was set, and while some states have now increased their limits to 65 or 70 mph, this day is still a reminder of just how important it can be to follow posted speed limits. So let's celebrate by driving safely and responsibly!
