Many people ask this before starting CDL school. They worry about past mistakes, driving records, or medical issues. Some simply assume they won’t qualify before they even try.
In most cases, those fears end up being unwarranted. Most people who want a CDL can qualify.
Still, certain issues can prevent someone from obtaining or keeping a commercial license. These rules exist because CDL drivers operate large, powerful vehicles, and safety is of utmost importance.
Here’s what genuinely disqualifies someone from getting a CDL in Washington.
Before looking at disqualifiers, let’s start with the basics.
To pursue a CDL in Washington, you must:
Most students meet these requirements without issue.
The real concern is usually past driving history or medical eligibility.
Driving under the influence is the most serious CDL disqualifier.
A first DUI usually results in a one-year CDL disqualification.
A second DUI can lead to lifetime CDL disqualification.
This rule applies even if the DUI occurred in a personal vehicle.
Commercial drivers also face stricter alcohol limits. The legal limit while operating a commercial vehicle is 0.04%.
That is half the limit for regular drivers.
Leaving the scene of an accident is another major offense.
Drivers must remain at the scene and cooperate with authorities.
Failing to do so usually results in a one-year CDL disqualification.
Commercial drivers are held to a higher standard because they operate heavy equipment in public spaces.
Using a vehicle during a felony can also disqualify a driver.
Examples include:
Some of these offenses can lead to permanent CDL disqualification.
Each case depends on the severity of the crime.
Some disqualifications happen slowly, because a pattern of unsafe driving can lead to suspension.
Serious traffic violations include:
Two serious violations within three years can lead to a CDL suspension, while three violations usually trigger longer disqualifications.
So yes, having a safe driving history does matter.
All CDL drivers must pass a Department of Transportation physical exam that tests if a driver can safely operate commercial vehicles.
Certain medical conditions can affect eligibility, including:
However, many drivers still qualify through medical waivers, and a certified DOT medical examiner will be the one to make that final decision.
Vision standards are strict but manageable.
To qualify, drivers must usually have:
Corrective lenses are allowed, and many CDL drivers wear glasses or contacts. In those cases, the license simply requires corrective lenses while driving, so this typically isn’t an issue.
All CDL drivers must participate in drug and alcohol testing programs.
Testing occurs at several points:
Failing a drug test triggers a return-to-duty process that includes evaluation, possible treatment, and follow-up testing.
Until this process finishes, the driver cannot operate commercial vehicles.
A criminal record does not automatically disqualify someone from getting a CDL. Many drivers in the industry have past convictions, but certain offenses can create challenges.
Some of these include:
Even then, eligibility often depends on how much time has passed since the offense. On a second note, many employers also conduct background checks before hiring, so you’ll have to keep that in mind if you qualify for a CDL but then struggle to get hired down the road.
A few tickets usually don’t cause any problems, as most drivers have at least some minor violations. However, issues arise when the record shows repeated serious violations like reckless driving or license suspensions.
If your record shows these patterns, improving your driving history can help you get back into a place where you qualify for a CDL.
Patience and safe driving is often the only thing that resolves this issue, as hard as that may be to hear.
You cannot obtain a CDL if your regular license is suspended. You must restore your standard driving privileges first.
This process usually involves:
Once your license is valid again, CDL training becomes possible.
Many people assume they cannot qualify, but most applicants meet the requirements. Even drivers with past mistakes can pursue a CDL after waiting patiently for some time. The trucking industry continues to need trained drivers and that demand creates opportunities for people ready to work and learn.
Yes. A DUI can disqualify a driver from holding a CDL.
A first DUI usually results in a one-year CDL disqualification. A second DUI can lead to lifetime disqualification. This rule applies even if the DUI occurred in a personal vehicle.
Yes, in many cases.
A criminal record does not automatically prevent someone from getting a CDL. Many drivers in the trucking industry have past convictions, but certain crimes involving vehicles or drug trafficking can disqualify a driver.
Usually not.
A few minor tickets rarely cause problems, but disqualifications can arise when drivers have multiple serious violations, like reckless driving or excessive speeding.
All CDL drivers must pass a DOT physical exam, and some conditions can prevent approval. These include severe vision problems, uncontrolled diabetes, epilepsy, or serious heart conditions.
In some situations, these individuals can still qualify through medical waivers.
Yes.
Many CDL drivers wear glasses or contact lenses. Drivers must meet vision standards during the DOT physical exam, and if corrective lenses are required, the license will simply include that restriction.
No.
You must first restore your regular driver’s license. Once your license is reinstated, you can begin the CDL process.
Permanent disqualification is rare but possible.
It usually occurs after multiple major offenses, like repeated DUI violations or serious felony crimes involving vehicles. These penalties exist to protect public safety.
For most people, no.
If you hold a valid license, pass the DOT physical, and complete training, you can qualify for a CDL. Most applicants find that they meet the requirements once they begin the process.
