Intulon OVAPAS — Low Overpass Clearance & Vehicle Length Warning Device for RVs and Trucks

Know about the low bridge before your roof does. The Intulon OVAPAS is a standalone dash device that warns RV and truck drivers — with a loud two-tone alert and a glanceable e-ink message — when the road ahead has an overpass too low, or a stretch too restricted, for your vehicle. No subscription. No phone app. No internet while you drive. The largest warning database on the market 135,113 low-clearance and restricted structures on board — every one a real, documented structure stored on the device All 50 states + DC covered, including Alaska and Hawaii 5× the next-largest warning database (~26,000 structures) 22,586 structures at or below 14′ 9″ — the ones that matter most to tall vehicles Direction-aware alerts: 9 in 10 structures know which road the limit applies to. Drive across a bridge and the OVAPAS stays quiet; approach the underpass beneath it and it speaks up. The rest simply always warn — never the other way around. Set it once. Then just drive. Set your vehicle — height and length, entered once with the two front buttons. The OVAPAS remembers them forever. Drive — it quietly watches the road ahead and shows the next overpass on record (clearance and distance) as you approach. Get warned in time — too low for your vehicle? A loud two-tone alert sounds at your chosen warning distance, repeats until you're past, and escalates as you close in. Built for the dash Sunlight-readable e-ink screen — stays legible in direct sun where phone screens wash out; adjustable backlight for night driving Fully offline — the complete hazard database lives on the device. Mountain pass or dead zone, warnings never depend on coverage Height and length — low clearances and posted vehicle-length restrictions (like switchback limits on mountain parkways) in one device Rechargeable — charges over USB with the included cable Free lifetime updates — a free updater app for Windows, macOS, and Linux fetches the latest firmware and hazard data and applies them over USB. No account, no pairing. The Intulon OVAPAS is a driver aid. Its warnings are a supplement only to posted signage and never a substitute for it. Clearance and restriction data may be incomplete or out of date; always obey posted limits and plan routes appropriate for your vehicle.
