RouteAllPlanning Your First Permitted Route
Last verified September 8, 2026 against the Oklahoma, Texas and Utah rules linked below.
A permitted route is the exact set of roads your permit names, and it is rarely the shortest way. In Oklahoma, leaving that route can invalidate the permit outright. You drive the roads on the paper, not the roads a car app picks.
This guide walks one route from permit to first mile.
In one minute: get the permit for each state, read the route it names road by road, then check the conditions attached to it. Those conditions carry the curfews, the weather limits and the escort requirement.
Drive the named roads. A detour you make on your own is not covered by the permit you are carrying.
What is a permitted route?
It is the specific list of highways the issuing state approved for your load. The state picks it by checking bridge clearances, weight capacity and construction against your dimensions. Texas calls this the most practical route, which is not the same as the shortest one, and it prints the result on the permit.
"A permitted vehicle will be routed over the most practical route available taking into consideration" clearances, restrictions and traffic conditions. — 43 Tex. Admin. Code 219.11(e)(2)(A). Verified September 8, 2026.
Oklahoma words it differently and requires the shortest practicable routing. Both states are choosing roads your load physically fits on.
A low bridge does not care which route was faster.
What happens if you leave the route?
In Oklahoma the permit can be void immediately. The rule ties permit validity to compliance with its own terms, and routes of travel are named directly in that list. A voided permit means the load on your trailer is no longer authorized, on any road, at that moment.
"failure of the vehicle owner or driver to comply with any applicable law, rule, regulation, ordinance, posted speed limit or any permit term, condition, limitation or requirement including, but not limited to routes of travel may, in addition to all other legal remedies, immediately invalidate the permit." — OAC 730:50-5-3. Verified September 8, 2026.
Texas takes a different approach and issues a second permit when the applicant wants a route other than the most practical one.
- Oklahoma ties permit validity directly to following the route named on it.
- Texas requires a second permit rather than voiding the first.
- Neither state lets you choose a replacement road on your own judgment.
If construction blocks the permitted route, call the issuing office before you turn.
You must not reroute around a closure on your own judgment. Stop and call the permit office; a detour you invent is not a permitted road.
The full consequence chain is in what happens if you leave your permitted route.
What conditions ride with the permit?
Three kinds, and they are enforced separately from the route itself. Time-of-day rules limit when you may move, and curfews close specific corridors at specific hours. Weather rules stop the move outright. Each one is printed on the permit or published by the state, and you must read both.
- Daytime only is the Texas default for a permitted vehicle, unless a listed exception applies.
- Curfews are published by the Texas department separately, and the operator must observe them.
- Weather stops a wide Utah load when snow or ice is on the road. The rule lists 10 feet wide, 105 feet long "and" 10 feet of overhang.
- Visibility below 1,000 feet stops that same Utah load, day or night.
- Carry the permit in Oklahoma, as the original or a true and correct copy.
"No carrier may operate an oversize vehicle or load more than 10 feet wide, 105 feet long, and 10 feet front or rear overhang when the following conditions exist: (a) any accumulation of snow and ice on the roadway; or (b) visibility less than 1,000 feet." — Utah Admin. Code R909-2-11(2). Verified September 8, 2026.
Fog is a stop, not a slowdown, on a wide load in Utah.
How do you plan the route step by step?
Seven steps, in this order. Measure first and permit last, because the permit application asks for the numbers you measure. Each state on the route is a separate application, so a four-state run means four permits and four sets of conditions to read before the first mile.
- Measure the load on the trailer: width, height, length, gross weight and overhang front and rear.
- List the states the route crosses. Each one issues its own permit.
- Apply per state, giving the same measured numbers to every one of them.
- Read the route the permit names, road by road, before you accept it.
- Read the conditions: travel hours, curfews, weather limits and escort requirements.
- Book escorts for each state that requires them at your dimensions.
- Share the route with your escort before the move, not at the yard gate.
Step four is the one new drivers skip. Read the roads before you accept the permit, because a route you cannot drive is easier to fix before it is issued.
How does the app fit in?
It turns the roads on your permit into navigation. RouteAll reads the permit you upload and drives the route it names, so the roads on the screen are the roads on the paper. You can also build a route by hand, and turn-by-turn navigation runs along whichever route you built.
All three of those are free.
Sharing that route with your escort is free to view, with no account needed on their side.
What it does not do is decide anything. It does not issue the permit, choose the route, or judge whether a road is legal for your load.
The permit decides. The app follows it.
Before you roll
The permitted route is the only route your permit covers, and in Oklahoma leaving it can invalidate the permit on the spot. Read the roads and the conditions before you accept the permit, not at the on-ramp. If the route is blocked, stop and call the issuing office rather than choosing a road yourself.
Common questions
Is the permitted route always the shortest route?
No. Texas routes a permitted vehicle over the most practical route available, considering clearances, restrictions and traffic. That is often longer in miles than the direct line, because the direct line may run under a bridge your load cannot clear. Miles are not the criterion; fit is.
Can I detour around construction on my own?
No. Stop and call the office that issued the permit. In Oklahoma, failure to comply with any permit term including routes of travel may immediately invalidate the permit. A detour you choose yourself is not a permitted road, even when the permitted road is closed.
Do I need a permit for every state on the route?
Yes. Permits are issued state by state, so a route crossing four states needs four separate applications. Each permit names its own roads, its own travel hours and its own escort requirement. Read all four sets of conditions before the first mile, not at each border.
What weather stops an oversize move?
It depends on the state and your dimensions. Utah's rule names a load over 10 feet wide, 105 feet long and 10 feet of overhang, joined by "and". Snow or ice on the roadway triggers it, and so does visibility below 1,000 feet. Read your permit, and check the rule for every state you cross.

RouteAll reads the permit you provide. It does not issue permits or guarantee compliance. The driver remains responsible for the load. Rules change; verify against the permit and the issuing state before every move.
