That gap matters. It affects where you can drive, who will hire you, and what kind of money you can realistically make starting.

A Commercial Driver’s License, usually just called a CDL, is what you need to legally operate large vehicles like semis, buses, and other heavy equipment used for work.

What’s the difference between intrastate and interstate driving?

This is where the age rule actually comes into play.

Intrastate driving means everything stays inside one state. You’re picking up, delivering, and operating without crossing state lines.

Interstate driving is broader than people think. It includes crossing state lines, but also hauling freight that’s part of a load moving between states, even if your route looks local on paper.

If you’re under 21, you’re limited to intrastate work. There’s no way around that under federal rules.

What is the minimum age to get a CDL?

You can get your CDL at 18 in most states. At that point, you’re legally allowed to drive a commercial vehicle, just not across state lines.

Turning 21 changes things in a big way. That’s when interstate restrictions drop off, and suddenly a lot more jobs are on the table.

Most larger carriers won’t even consider drivers under 21. That’s partly because of the law and partly because of insurance policies.

What can you actually do at 18 versus 21?

It helps to look at this side by side:

Most drivers in that 18–20 range are focused on getting experience, not chasing the highest pay right away.

What kind of jobs can you get at 18?

You’re not stuck, but you do have to be realistic.

A lot of drivers start with local work. That might be delivering for a warehouse, running a dump truck, doing yard moves, or hauling materials for construction jobs. Agricultural work is another common starting point, depending on where you live.

These jobs might not be flashy, but they do something important. They help you build a clean record, which matters a lot when you move up later.

Why do you have to wait until 21?

This comes down to federal rules and risk.

Interstate trucking falls under federal regulation, and the minimum age is set at 21. On top of that, insurance companies are stricter with younger drivers, so employers follow those limits even when they technically don’t have to.

So it’s not just a legal thing. It’s how the whole system is set up.

What changes when you turn 21?

This is where things usually open up pretty quickly.

You can apply to larger carriers, take longer routes, and move freight across state lines. Pay tends to improve too, especially if you move into over-the-road positions that pay by the mile.

For a lot of drivers, this is when the job starts to feel like a real career path instead of just getting started.

How long does it take to get a CDL?

If you go through a full-time training program, you’re usually looking at somewhere between three and eight weeks.

You’ll start with a Commercial Learner’s Permit, then spend time actually driving, and finally take a skills test that covers inspection, control, and road driving.

Some companies offer paid training, but that usually comes with a commitment to stay for a certain amount of time.

How do age limits affect your pay early on?

This is where the difference shows up fast.

Local and in-state jobs generally pay less than long-haul work. So even if you’re working steadily at 18 or 19, your earning potential is more limited.

Once you hit 21 and can run interstate routes, you usually have access to better-paying loads, more miles, and more consistent work.

Frequently asked questions

What is the minimum age to get a CDL?
You can get a CDL at 18, but you need to be 21 to drive interstate or haul interstate freight.

Can you drive a semi truck at 18?
Yes, but only within your home state.

Do you have to be 21 to be a truck driver?
No, but most long-haul and higher-paying jobs require it.

Why do companies require drivers to be 21?
Insurance rules and federal interstate regulations both play a role.

Can you cross state lines under 21?
No, that’s not allowed.

How long does it take to get a CDL?
Most people finish training in three to eight weeks.

Getting your CDL at 18 is a solid way to get started, but it’s only part of the picture. Those first couple of years are about learning the job and building experience. Once you turn 21, a lot more doors open, and that’s when most drivers start seeing the full range of opportunities the industry has to offer.

The Calm Before a Freight Storm

Right now, trucking feels stuck in neutral. Freight demand is weak, spot rates have cooled, and both carriers and brokers are under strain. Many in the industry describe this moment as the calm before the storm, with indicators pointing toward a major correction that could rival the market chaos of the COVID years.

The warning is clear: if 600,000 drivers leave the market, capacity will tighten quickly and spot rates could skyrocket. Unlike during the pandemic, there will be no surge of new immigrant drivers to fill the gap. That relief valve, once supported by open immigration policies, is now closed. Carriers will have to compete harder for qualified drivers through better pay, sign-on bonuses, and improved working conditions.

What’s Fueling the Freight Downturn

Freight volumes are down 18 percent year over year, hitting carriers of every size. For freight brokers, the challenge is even tougher. With fewer loads to move, margins have evaporated. Some are stuck with contract rates signed too low to stay profitable, forcing them to compete against asset-based carriers while losing money on every run.

Small fleets are feeling the squeeze most. Many have relied on non-domiciled CDL drivers, but new federal regulations around English Language Proficiency are cutting off that supply. On top of that, fraud in load boards and verification systems has exploded. Scammers have found ways to manipulate tools like Highway and RMIS, forcing brokers to be more cautious.

That means even legitimate carriers can be flagged by mistake. Once that happens, they can be locked out of most brokerage freight entirely, which can be a death blow for smaller operations already struggling to stay afloat.

How New Rules Could Wipe Out 600,000 Drivers

This expected capacity purge ties directly to federal regulatory changes and immigration enforcement already underway. According to research from J.B. Hunt, new rules for non-domiciled CDL holders and English Language Proficiency requirements could remove between 214,000 and 437,000 drivers, roughly 5 to 12 percent of the U.S. driver pool over the next few years.

On September 26, 2025, the Federal Motor Carrier Safety Administration issued an emergency ruling that restricts the issuance and renewal of non-domiciled CDLs. Officials estimate that 97 percent of the 200,000 drivers who currently hold those licenses will not meet the new standards and will likely exit the industry within three years. That alone represents 5 percent of all registered CDLs in the country.

Stricter enforcement of English Language Proficiency standards has already led to 23,000 violations, including 5,000 out-of-service orders. Analyst Avery Vise projects that this enforcement could sideline about 20,000 drivers each year.

When combined with limits on undocumented drivers and new hiring restrictions, transport economist Noël Perry estimates that more than 600,000 drivers, about 17 percent of the active workforce, could be removed from trucking.

Carriers that rely heavily on immigrant labor or those unable to comply with the new regulations may not survive this purge.

The Economic Ripple Effect

These rule changes, combined with a long freight recession, are creating a perfect storm for widespread bankruptcies. Both carriers and brokers are tightening budgets and consolidating operations as the industry braces for a market reset.

The shakeout is expected to favor larger, well-capitalized carriers who can handle the new compliance demands and stay profitable through the downturn. Smaller carriers that grew quickly during the post-COVID freight boom may not have the financial cushion to adapt.

As capacity tightens, driver pay is likely to rise. Carriers will need to offer stronger incentives to attract qualified drivers from a shrinking talent pool. The shift could finally bring the market back to a more balanced place where supply and demand set the rates naturally instead of desperation driving them down.

What Comes Next

The road ahead will be rough, but it could lead to a healthier trucking market. Analysts predict that after the purge, spot rates will rise again, contract rates will stabilize, and carriers that survive will see more consistent freight and fairer pricing.

The exact timing of this recovery is uncertain, but the direction is clear. Shippers should prepare for higher rates and tighter capacity, while carriers who manage to weather the storm will be well-positioned when freight rebounds.

As one industry expert put it, “If volumes pop—which doesn’t exist right now—hold on to your hat. It’s going to be one of the best freight markets that carriers have seen in some time.”

It may take time and patience to reach that point, but for those who make it through, the rewards could be worth the wait.

Current Regulations and Bianco’s Proposal

Currently, federal regulations limit drivers under the age of 21 to operating commercial motor vehicles (CMVs) exclusively within their state of residence. Bianco, however, seeks to expand access to its training services to non-Michigan residents under this exemption.

The training center is located just 29 miles from the Wisconsin border, making it a convenient option for many Wisconsin-based students. According to FMCSA, Bianco shared that several young aspiring drivers from Wisconsin have expressed interest in joining because the facility is their nearest registered training provider.

Bianco also outlined safety precautions in its application. Under their proposal:

• Under-21 drivers would only operate CMVs when accompanied by a licensed training instructor.

• All range maneuvers would take place on Bianco’s insured and managed training lot.

• Every student must pass a pre-employment drug screening before beginning the program.

Public Input Requested

FMCSA is currently seeking public feedback on Bianco’s petition. Comments can be submitted through Feb. 14 here.
