Understanding Major Violations and CDL Disqualifications in Colorado: Protecting Your Commercial Driver’s License

Commercial truck drivers are essential figures in the transportation sector, facilitating the smooth transit of goods along Colorado’s highways. Yet, along with this duty, comes the requirement to comply with stringent regulations established by the Federal Motor Carrier Safety Administration (FMCSA). When commercial truck drivers commit violations of FMCSA statutes, the consequences can be severe, potentially leading to the temporary or permanent loss of their Commercial Driver’s License (CDL). This article will explore the concept of major violations and the resulting disqualifications of Commercial Driver’s Licenses (CDLs). We will also introduce you to Thomas & Ahnell, LLC, a trusted law firm specializing in alcohol and drug-related driving offenses in Colorado.

Understanding Major Violations

FMCSA statutes categorize violations differently based on their severity. Major violations are considered the most serious and carry a minimum punishment of one year of CDL disqualification. If hazardous materials are involved, the disqualification period extends to three years. Commercial truck drivers must be aware of these major violations, which include:

  1. Driving a commercial truck while under the influence of alcohol.
  2. Driving a commercial truck while under the influence of any controlled substance.
  3. Driving a commercial truck with a blood alcohol concentration (BAC) of .04 or greater.
  4. Refusal to consent to an alcohol test.
  5. Fleeing the scene of an accident.
  6. Operating a Commercial Motor Vehicle (CMV) under a revoked, suspended, or canceled license or when the driver has been disqualified.
  7. Causing a fatality, whether charged with vehicular manslaughter, vehicular homicide, or negligent homicide.

It is important to note that a single major violation can result in a minimum one-year CDL disqualification, significantly impacting a driver’s livelihood.

Lifetime CDL Disqualification: A Dire Consequence

In some instances, a CDL-certified driver can face a lifetime ban on their CDL. This serious repercussion arises when a driver employs a vehicle in the commission of a felony related to the production, distribution, or dispensation of a controlled substance. A lifetime CDL disqualification leaves no room for reinstatement, forever altering a person’s career prospects and financial stability.

Protecting Your CDL and Future

Given the potentially devastating repercussions of a CDL disqualification, especially for commercial truck drivers who rely on their licenses for their livelihoods, seeking legal counsel is essential. If you’re facing a significant violation of the FMCSA code, such as driving under the influence, seeking advice from an experienced Denver DUI attorney is recommended.
