HeadRoom gives truck drivers and RV travelers turn-by-turn navigation that knows your vehicle's height — automatically routing around low bridges, tunnels, and overhead hazards before you reach them.
A real walkthrough of HeadRoom — from entering a destination to getting a clearance-safe route.
Live bridge clearance overlaid on your route as you drive.
Proactive warnings miles before you reach a low clearance.
Full details on every hazard including clearance, heading, and distance.
Compare safe routes vs fastest routes and choose the best path.
Google Maps, Apple Maps, and Waze have zero bridge clearance awareness. A single bridge strike can total your vehicle, injure passengers, and cost tens of thousands in damage and fines. HeadRoom solves this.
Set your vehicle's exact height once. HeadRoom's SafeRoute continuously scans your route for bridges, tunnels, and overhead obstructions — recalculating in real time to keep you on a path that fits.
Full voice guidance powered by Google Cloud TTS so you never need to look at the screen while driving. HeadRoom tells you where to turn and warns you about upcoming hazards.
Even when you are not actively navigating, Sentry Mode runs in the background and monitors your proximity to low bridges. If you approach a hazard, you get an immediate alert.
Know which direction a bridge is dangerous — no false warnings if you are on the safe side of a structure. Only HeadRoom offers this level of directional precision.
If a low bridge is detected along your current route, HeadRoom instantly recalculates an alternative route that clears all overhead obstacles, without waiting for you to notice the problem.
Pairs with your existing Low Clearance Map account. One subscription, full access on both the mobile app and the web platform.
