Michigan Commercial Driver License (CDL)
Federal Requirements, Testing & Disqualifications
Commercial Motor Vehicle Safety Act of 1986
The Commercial Motor Vehicle Safety Act of 1986 was signed into law on October 27, 1986. The goal of the Act is to improve highway safety by ensuring that drivers of large trucks and buses are qualified to operate those vehicles and to remove unsafe and unqualified drivers from the highways.
The Act retained the State's right to issue a driver's license, but established minimum national standards which States must meet when licensing CMV drivers.
It is important to note that the Act does not require drivers to obtain a separate Federal license; it merely requires States to upgrade their existing testing and licensing programs to conform with Federal minimum standards.

• Active military duty operating military vehicles
• Police and firefighters operating authorized emergency vehicles

Michigan's Drunk Driving Laws Affect CDL License
BAC Standards:
FHWA has established 0.04% as the blood alcohol concentration (BAC) level at or above which a CMV driver is deemed to be driving under the influence of alcohol.
States maintain a BAC level between .08% and .10% for non-CMV drivers.
Revocation Periods:
- 1 year:First violation (3 years if transporting hazardous material)
- Life:Second violation, regardless of time between violations (possibility of reinstatement after 10 years)
Important: These revocations apply to a CDL driver while operating ANY motor vehicle.
When operating a noncommercial motor vehicle, the alcohol content of .08 BAC would be used to determine a drunk driving violation.
Other violations resulting in revocation:
- • Leaving the scene of an accident
- • Using a vehicle to commit a felony
- • Refusing a request for a chemical test
These laws are contained in Act 300 of the Michigan Vehicle Code, Sections 257.319b and 257.625. Amendments extending these revocations to noncommercial vehicles became effective October 1, 2005.
Knowledge & Skills Tests
Knowledge Tests:
- • The general knowledge test must contain at least 30 questions
- • To pass, applicants must correctly answer at least 80 percent of the questions
- • States develop their own tests which must be at least as stringent as Federal standards
Skills Tests:
- • Applicants must successfully perform all required skills (listed in 49 CFR 383.113)
- • Skills test must be taken in a vehicle representative of the type the applicant operates or expects to operate
Third Party Skills Testing:
- • States, employers, training facilities, and private institutions can serve as third party skills testers
- • Tests must be the same as those given by the State
