What "Lower 49 States" Means on a GPS

When a GPS device refers to the "lower 49 states," it means the 48 contiguous United States plus the District of Columbia — essentially all US states except Alaska and Hawaii.

Breakdown

• 50 States Total: 48 contiguous + Alaska + Hawaii.
• "Lower 48": Common term for the contiguous states (excluding AK & HI).
• "Lower 49": Less common; likely includes DC (federal district, not a state) or is a misnomer for "lower 48."

Why GPS Uses This

• Map Data: Alaska and Hawaii are non-contiguous; separate map tiles, different projections.
• Routing: No road network connects them to the lower 48.
• Weather/Traffic: Separate forecasting zones.
• Time Zones: AK (AKST/AKDT), HI (HST) vs. 4 zones in contiguous US.

So yes, "lower 49 states" in GPS context = United States minus Alaska and Hawaii (usually meaning the contiguous 48 + DC).
