For charter & tour coach drivers

Hear the low bridge before you see it.

MotorcoachNav rides along on your iPhone and speaks up before every railroad crossing and every low clearance ahead, checked against the height of the coach you're driving today.

11′ 8″
MotorcoachNav says
Low clearance ahead in 1,800 feet. 11 feet 8 inches. Too low for this coach.

What it does

Eyes on the road. The app does the reading.

You set it up before you pull out. After that you never touch the phone: alerts are spoken, other audio ducks under them, and they play even with the phone on silent.

Railroad crossings

Every public grade crossing from the federal crossing inventory, matched to the actual rail line. Crossings on side streets you're driving past stay quiet.

"Railroad crossing ahead in 1,200 feet. Gates."

Low clearances

Low bridges from the National Bridge Inventory plus railroad bridges, tunnels and canopies from OpenStreetMap. It knows going under a bridge from driving over it.

"Low clearance on the lower level."

Sized to your coach

Keep every coach you drive, by bus number or model, and pick today's. You enter the height; a safety margin of 6 inches is added unless you change it.

"12 feet 9 inches. Check the posted height."

Trip tab

Plan from where you are, or set a starting point like the yard or a pickup. Pick a destination and see up to three routes, each listing every low clearance and crossing that matters for your coach, by mile. The safest one comes first.

"On your route: low clearance in 1 mile, too low for this coach."

Drive log

Every alert, every crossing you drove over and every low structure you went under is written down on its own, ready to share after the trip.

Fresh data, every week

The nationwide clearance file is rebuilt weekly from federal and OpenStreetMap data and checked for updates daily. You can keep updates to Wi-Fi only.

Approaching a low bridge

Timed by your speed, not a fixed distance.

Alerts come a set number of seconds out at the speed you're driving, so there's the same time to react at 25 mph in town as at 60 on a two-lane.

ABOUT 1 MILE OUT

Route heads-up

When you're driving a checked route, a clearance too low for the coach gets an early warning, even around a turn the GPS can't see yet.

ABOUT 30 SECONDS OUT

First alert

Roughly 1,000 to 2,600 feet ahead: what's coming, the height, and whether it's too low or just close.

"Low clearance ahead in 1,800 feet."

ABOUT 10 SECONDS OUT

Second alert

A short reminder right before the structure, in case the first one was talked over.

Your coach

Built by a driver, for the coaches drivers actually run.

Pick the make, model and year and the length, width, weight and axles fill in from the maker's spec sheets. The height is always yours to enter: the height posted in the cab, with anything on the roof counted.

Posted signs come first

MotorcoachNav is a driving aid. It doesn't replace posted signs, signals or your judgment. Resurfacing, snow and damage can change a clearance, and public data can be missing or out of date. No alert doesn't mean the way is clear.

You'll accept the full Terms of Use in the app before your first drive.
