Michigan runs on automotive. Assembly plants and the supplier network around them move parts on schedules measured in hours, which makes for steady, well-paying freight if you can hit appointments. Add two of the busiest Canadian border crossings in North America and a spring weight-restriction season nobody warns you about.
Southeast Michigan is the densest automotive manufacturing cluster in the country — assembly plants plus hundreds of tier-one and tier-two suppliers feeding them. That freight moves just-in-time, which means narrow appointment windows and real consequences for missing them, and it pays accordingly. The trade-off is that automotive freight is cyclical: plant shutdown weeks in summer and around the holidays pull a lot of volume out of the market at once, and drivers who have not planned for it sit. We build Michigan carriers a mix so a shutdown week is not a zero week.
From roughly March into May, Michigan cuts legal axle weights on many roads while the ground thaws. A load that is legal in February can be illegal on the same route in April. We check restrictions before we book you, not after you are loaded.
Michigan is unusual: for intrastate freight, its multi-axle configurations allow gross weights far above the 80,000-pound federal interstate limit, which is why you see long multi-axle "Michigan trains" hauling aggregate and steel in-state. If you are running interstate on standard equipment, that does not help you, and it means some Michigan shippers expect capacities you cannot legally deliver across a state line. On the other side, seasonal frost laws restrict weights on many non-interstate routes during the spring thaw. Both rules matter at booking time, and both get checked before we commit you to a load.
Automotive freight rewards reliability more than almost any other segment — hit your appointments and the same brokers keep calling. We will build you a lane mix that survives shutdown weeks. New authority? See our New Authority dispatch page, or read the 4-step process.
In spring, as frozen ground thaws, Michigan reduces legal axle weights on many county and state roads to prevent pavement damage. Restrictions typically run from roughly March into May and vary by region and year. They can make a normally legal load illegal on a given route, so we verify current restrictions before booking.
Yes. JIT parts freight is a large share of Michigan volume and pays well, but it runs on narrow appointment windows with real penalties for missing them. We only put carriers on it who want that kind of run.
For intrastate freight on certain multi-axle configurations, yes — Michigan permits substantially higher gross weights than the 80,000-pound federal interstate standard. That does not apply to standard interstate equipment crossing state lines, which is why we confirm what a shipper actually expects before you commit.
We book freight through the Detroit and Port Huron crossings for carriers set up for cross-border work and coordinate the customs paperwork. Your authority and border credentials have to be in place first.
Volume drops sharply during summer and holiday shutdowns. We plan for it by keeping you on a mix of automotive, general freight and west-Michigan manufacturing rather than leaving your whole week dependent on one plant schedule.
