About this app
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.

EIGHT LANGUAGES
English, Spanish, French, Haitian Creole, Punjabi, Hindi, Portuguese and

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.
