Trucker GPS: Scales & Bridges

RBS (Routes, Bridges & Scales) is the map built for truck drivers running the DMV corridor — Virginia, Maryland, and Washington, DC. See what no DOT site or generic map shows you in one place:

• Weigh stations, rest areas, low-clearance bridges, and fuel stops on a live map
• Sourced state size & weight rules for VA, MD, and DC — every card cites its source
• Real driver-reported tips on each scale — what actually gets checked here, from the drivers
who ran it (labeled driver-reported, not official)
• Hands-free voice reporting — tap the mic and call out what's ahead without touching the keyboard
• Earn points for adding locations, verifying pins, posting tips, and logging what got flagged

Driver tips are anecdotal and clearly labeled. Where a tip and the sourced state-rules card disagree, the sourced card is always what we show as the rule.

DISCLAIMER: RBS is an independent app. It is not affiliated with, endorsed by, or operated by any government agency or Department of Transportation. State rules shown in the app are a plain-language summary of official government sources — always confirm current law with the official source.
