Michigan Commercial Driver DUI Lawyer

In Michigan, commercial driver’s license (CDL) holders are held to stricter standards than non-commercial drivers when it comes to alcohol-related driving offenses. For example, a non-commercial driver may be convicted of operating while intoxicated (OWI) for driving with a blood alcohol content of .08% or higher, while a CDL holder may face drunk driving charges for driving a commercial vehicle with a BAC of .04% or higher.

Out-of-Service Orders

Michigan also enforces out-of-service orders for CDL holders who violate certain regulations. An out-of-service order means that you cannot operate a commercial vehicle for 24 hours.

You may receive an out-of-service order for the following:

  • Consuming alcohol within four hours of operating a commercial vehicle
  • Consuming alcohol while operating a commercial vehicle
  • Having a BAC of .015% prior to or while operating a commercial vehicle
  • Refusing to take a preliminary breath test

Chauffeur License

In Michigan, you are required to hold a chauffeur license if your job entails transporting people or goods in vehicles up to certain capacities. For example, you must have a chauffeur license in order to drive:

  • A taxi
  • A limousine
  • A school bus
  • A public bus

CDL vs. Chauffeur License

A chauffeur license essentially is a step between an ordinary operators license (commonly referred to as a drivers license) and a commercial drivers license (CDL). In Michigan, a chauffeur license authorizes you to operate vehicles weighing up to 26,000 pounds or that can carry up to 15 passengers. However, you will need to obtain a CDL if your job requires you to operate a vehicle that:

  • Weighs 26,001 pounds or more
  • Can carry 16 or more passengers
  • Transports hazardous materials in amounts that require placarding

OWI Penalties for CDL Holders

If you are arrested for and found guilty of drunk or drugged driving, you could face a period of license suspension, even if it is your first offense. If you depend on your CDL or chauffeur license for work, this could mean time off from your job or, even worse, the loss of employment altogether. To make matters worse, if you are caught driving under the influence while transporting passengers, you could face additional criminal charges.
