HeadRoom is the essential navigation companion for truck drivers, RV owners, and anyone hauling oversized loads. Built by Low Clearance Map, the team behind the most comprehensive bridge clearance database in the world, HeadRoom combines real-time bridge monitoring with clearance-aware routing so you always know what's ahead before you get there. Why HeadRoom? Standard navigation apps are built for passenger cars. They have no idea your rig is 13'6" tall. HeadRoom does. Every route it suggests accounts for your vehicle's height, keeping you away from low bridges, underpasses, and clearance-restricted roads that could stop your trip cold or cause serious damage. Only HeadRoom is powered by Low Clearance Map's industry-leading database, built from years of real-world data collection and continuous updates. No other app comes close. HeadRoom on CarPlay Take HeadRoom straight to your dash. The full clearance-aware experience runs right on your vehicle's display, with bridge markers, SafeRoute turn-by-turn directions, and Sentry Mode alerts shown big, bright, and glanceable, so your eyes stay on the road and your phone stays in your pocket. Sentry Mode: Real-Time Bridge Monitoring HeadRoom's Sentry Mode continuously monitors bridge clearance data across the country so you get the most current information available. When conditions change or a clearance is flagged, you'll receive an alert before it becomes your problem. Sentry Mode runs quietly in the background, watching the road ahead so you don't have to. SafeRoute: Clearance-Aware Routing Enter your vehicle height and let SafeRoute do the rest. Our routing engine calculates paths that avoid low-clearance hazards, giving you turn-by-turn directions you can actually trust. Whether you're crossing the country or running a local delivery route, SafeRoute finds the safest path for your specific vehicle every single time. Built for the People Who Drive for a Living HeadRoom was designed with real truckers and RV drivers in mind. The interface is clean, readable at a glance, and built to work the way you actually drive. No clutter, no unnecessary features, just the clearance information and routing you need to get where you're going safely.
