CDL Navigator: GPS Truck & Bus
Low bridges, weigh stations
Free · Designed for iPad. Not verified for macOS.
A car GPS does not know you are 13 feet 6 inches tall. CDL Navigator does, and
that is why it sends you a different way.
YOUR MEASUREMENTS DECIDE THE ROUTE
You enter height, width, length, gross weight, axle count and, if you carry
it, the hazmat class and tunnel category. Every route uses those numbers. That
includes kingpin-to-rear-axle (KPRA), which California posts routes by and
fines for, and which almost no other app asks about.
Nine vehicle types, each with ITS own rules: tractor-trailer, straight truck,
school bus, motorcoach, RV, car hauler, tanker, flatbed and delivery van. A
school bus is routed under bus law, not truck law — a legal difference, not a
detail.
IF IT ONLY JUST FITS, YOU DO NOT GO
Measurements are rounded UP, and three inches of clearance are added to height
and width. Your vehicle is declared taller and wider than it is, on purpose.
The reason: the clearance posted on a bridge was measured the day the sign
went up, and every layer of asphalt since has lowered the real clearance
without anyone changing the number. Three inches cost about a quarter mile of
detour. Six inches can double whole routes.
And if no path exists that respects all your measurements, the app does NOT
just show you the route. It stops you, names the measurement being broken, and
makes you acknowledge it before you drive.
WHAT YOU SEE WHILE DRIVING
• The speed limit for the road you are on, drawn like the real sign, changing
as you move from street to street. When it is not known, nothing is shown —
no invented number. You read the sign instead.
• Your current speed right below it, so the comparison takes one glance.
• Traffic painted on your route in amber, orange or red. Sections with no data
are NOT painted green, because "I don't know" and "it's clear" are not the
same thing.
• A heads-up two miles before you cross into another state, where truck speed
limits, chain laws and weight permits change.
• Weigh stations: a warning at 50 miles so you can plan, and a second at 30
once you are rolling. The app says plainly that it CANNOT know whether a
station is open, and that you should assume it is.
• The map goes light and dark with the real sunset where you are, not by the
clock.
Notices last three seconds and clear themselves so they never sit on top of
the road ahead — but they are kept in the bell so you can read them parked.
WHERE THE DATA COMES FROM, AND WHAT IT DOES NOT COVER
Maps and truck routing come from HERE. Bridge clearances are cross-checked
against the FHWA National Bridge Inventory. Weather and rain radar come from
the National Weather Service. Average diesel prices come from two federal
sources, cross-checked against each other. Border wait times come from Customs
and Border Protection. Work zones come from the Department of Transportation.
Settings lists what each source gives you and what it does NOT: the diesel
price, for instance, is your region's average, not the pump across the street.
The app also checks by itself that the server is really applying your limits,
against a real bridge, and warns you if it stops.
EIGHT LANGUAGES
English, Spanish, French, Haitian Creole, Punjabi, Hindi, Portuguese and
Chinese. Not just the interface — the spoken directions too.
PRIVACY
No account and no sign-up. Vehicle profiles, trips and saved places stay on
your phone. The app is free with optional purchases and may show ads.
Location is used with the screen off while you navigate — otherwise the voice
guidance would cut out the moment you locked the phone. A permanent
notification always shows it, and it ends when you close the route.
WHAT THIS APP IS NOT
It does not calculate routes offline. That needs a separate contract with the
map provider, and we would rather say so than have you find out in the middle
of nowhere. Map tiles you already passed are cached.
Mile markers are Texas only for now.
Driving is still yours. Posted signs beat anything on any screen.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New in-house map, sharper at night, with an automatic backup if it fails to load. The map no longer resets: it keeps its position, orientation, and active route when you open other sections or minimize the app. Road signs and your destination stay put as the map rotates, and the camera zooms in at turns and on arrival. New option to show which way nearby streets run.
