What disqualifies you from getting a CDL in Alabama? If you’re looking into the requirements for a CDL, one of the first questions that likely comes to mind is what could prevent you from being approved. Because Alabama enforces strict eligibility standards, understanding these disqualifications is crucial. Having a clear picture of the rules will make your CDL application process smoother and help you avoid unnecessary setbacks. In this guide, Easy Prep breaks down everything you need to know. Let’s dive in!

What disqualifies you from getting a CDL in Alabama?

In fact, there are 8 common disqualifying factors you need to be aware of before obtaining your CDL:

Age demands

In Alabama, the minimum age to obtain a CDL for intrastate driving is 18. However, to operate across state lines (interstate) or transport hazardous materials, drivers must be at least 21 years old. Not meeting these age requirements will make an applicant ineligible for a CDL.

Medical state

The Department of Transportation (DOT) and the Federal Motor Carrier Safety Administration (FMCSA) require all CDL applicants to pass a thorough medical examination. Certain health conditions (particularly vision impairments, hearing loss, epilepsy, insulin-dependent diabetes, and cardiovascular diseases) can disqualify an individual from obtaining a CDL. These conditions may compromise the driver’s ability to operate a commercial vehicle safely, posing potential risks to both the driver and others on the road.

Drug or alcohol abuse

Drug or alcohol abuse

You will lose your CDL for at least one year for a first offense if you are convicted of any of the following:

  • Driving a CMV with a Blood Alcohol Concentration (BAC) of 0.04% or higher
  • Operating a CMV under the influence of alcohol
  • Refusing to submit to a blood alcohol test
  • Driving a CMV under the influence of a controlled substance
  • Leaving the scene of an accident involving a CMV
  • Committing a felony involving the use of a CMV
  • Driving a CMV while your CDL is suspended
  • Causing a fatality due to the negligent operation of a CMV

A history of alcohol or drug-related driving offenses (including prior DUI convictions) can also result in disqualification from holding a CDL. In addition, a positive result on any mandatory drug test will immediately trigger suspension or revocation of your CDL privileges.

Driving history

A clean driving record is a crucial factor in obtaining and maintaining a Commercial Driver’s License (CDL). Multiple traffic violations can put your CDL at risk, especially when they are classified as serious traffic offenses, such as:

  • Excessive speeding (15 mph or more over the posted speed limit)
  • Reckless driving
  • Improper or erratic lane changes
  • Following another vehicle too closely
  • Traffic violations committed in a CMV that are connected to fatal accidents
  • Operating a CMV without holding a valid CDL or without carrying your CDL in possession
  • Driving a CMV without the correct class of CDL and/or required endorsements

A history of serious violations reflects poor judgment and irresponsibility behind the wheel. This raises major safety concerns not only for the driver but also for other motorists, and it can ultimately lead to the suspension or revocation of CDL privileges.

Hazardous materials endorsement background check and disqualifications

Hazardous materials endorsement background check and disqualifications

If you require a hazardous materials endorsement, you must submit fingerprints and undergo a background check.

You will be denied or will lose your hazardous materials endorsement if you:

  • Are not a lawful permanent resident of the United States
  • Renounce U.S. citizenship
  • Are wanted or under indictment for certain felonies
  • Have been convicted in military or civilian court of certain felonies
  • Have been adjudicated as mentally defective or committed to a mental institution
  • Are determined by the TSA to pose a security threat

Background check procedures vary by jurisdiction. Your licensing agency will provide the information needed to complete the TSA background check.

Railroad-Highway grade crossing violations

Railroad-Highway grade crossing violations

You will lose your CDL:

  • For at least 60 days for a first violation
  • For at least 120 days for a second violation within a three-year period
  • For at least one year for a third violation within a three-year period

These violations include failing to:

  • Stop before reaching the crossing when tracks are not clear (for drivers not always required to stop)
  • Slow down and check that tracks are clear of an approaching train (for drivers not always required to stop)
  • Stop before driving onto the crossing when required to always stop
  • Have sufficient space to drive through the crossing without stopping
  • Obey a traffic control device or enforcement official at the crossing
  • Negotiate a crossing because of insufficient undercarriage clearance

Criminal background

Background checks are an essential part of the Commercial Driver’s License (CDL) application process. Criminal convictions can significantly impact a driver’s eligibility for a CDL. Serious offenses (such as vehicular manslaughter, drug trafficking, or using a commercial vehicle to commit a felony) may result in a permanent disqualification from holding a CDL.

Even less severe crimes, including misdemeanors, can also jeopardize CDL eligibility depending on the nature of the offense and the applicant’s overall conduct. Ultimately, both the severity of the crime and the driver’s demonstrated responsibility are taken into account when determining whether a CDL can be issued or retained.

Immigration status

To obtain a Commercial Driver’s License (CDL) in Alabama, applicants must have lawful immigration status. Under federal regulations, undocumented immigrants or individuals with temporary or uncertain immigration status are not eligible to apply for a CDL. Valid documentation (such as proof of legal residency and an authorized work permit) is required to demonstrate eligibility and proceed with the application process.

FAQs

1. Can a felon get a CDL in Alabama?

Yes, a felon can obtain a Commercial Driver’s License (CDL) in Alabama, but there are some important restrictions and considerations:

  • Time since conviction: In general, a person with a felony conviction can apply for a CDL after a certain period of time has passed since their conviction. For most felonies, the waiting period is typically around 10 years from the completion of the sentence, including probation or parole.
  • Certain convictions may be disqualifying: Convictions related to drug trafficking, violent crimes, or crimes involving a motor vehicle (like vehicular manslaughter) may disqualify an individual from obtaining a CDL.
  • State vs Federal Law: Federal law also governs the eligibility for CDLs, and some federal restrictions may apply to specific felony convictions.

It’s always best to check with the Alabama Law Enforcement Agency (ALEA) or a local Department of Motor Vehicles (DMV) for specific details about individual circumstances.

2. Can you get a CDL with a DUI in Alabama?

Yes, it is possible to get a CDL after a DUI conviction, but it can be challenging, and there are restrictions:

  • First DUI offense: A first-time DUI conviction does not automatically disqualify a person from obtaining or keeping a CDL. However, if you are caught driving a commercial vehicle with a BAC of 0.04% or higher, you can face disqualification.
  • Second DUI offense: A second DUI conviction within 10 years will result in a lifetime disqualification from driving a commercial vehicle, unless the individual completes a specified waiting period (usually around 5 years) and meets certain conditions.
  • Impaired driving in a personal vehicle: If you are convicted of DUI in a personal vehicle, it may not immediately disqualify you from obtaining a CDL, but repeat offenses can make it harder.
