About this app

Never Get Caught Under a Low Bridge Again

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.

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.

Sentry Mode: Real-Time Bridge Monitoring
HeadRoom's Sentry Mode continuously monitors bridge clearance data so you get the most current information available. When a clearance hazard is detected nearby, 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. The 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 time.

Android Auto: Your Clearance Data on the Dash
HeadRoom works with Android Auto, so your clearance-aware routing and Sentry Mode alerts show up right on your vehicle's built-in display. Bigger screen, hands on the wheel, eyes on the road. You get glanceable turn-by-turn directions and low-clearance warnings without ever reaching for your phone.

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.

Ratings and reviews

App doesn't work or recognize that a subscription has been added. "Contact Us" link is broken as well. I can not complete the contact form as it doesn't let me continue without a phone number and the field to enter phone number does not accept the full phone number. Seems to not have enough character spaces available in the field. Tried multiple accounts and also by signing up via my phone number itself. App sends a verification code and then says that is incorrect too. Waste of time.

it doesn't load, freezes right away.

Needed a truck height map in a pinch and did the free trial. Unfortunately the app just keeps asking me to subscribe and never lets me actually use it. Never trusting app recommendations from Google AI search results again.. Trash app.
