What You Need To Know About Commercial Driver’s Licenses and DUI Regulations

If you are a truck driver, bus driver, or another professional who has a commercial driver’s license in Pennsylvania, you are held to a higher standard than other motorists in regards to driving while you are impaired.

There are state and federal regulations and laws that apply to you as a commercial driver, and the rules are stricter for you than they are for other drivers.

The Federal Motor Carrier Safety Administration promulgates federal regulations that govern commercial drivers, and each state has its own laws that also apply to drivers with CDLs within their boundaries.

There are good reasons why CDL drivers are regulated more strictly than other types of motorists. Commercial trucks and buses are much heavier and larger than other vehicles and can cause more damage when they cause accidents.

Buses carry passengers, including children, who can be seriously hurt if an accident happens. The stakes are simply higher when a commercial driver drives after he or she has drunk alcohol or ingested drugs.

If you are a commercial driver who is facing DUI charges, the legal team at DiCindio Law may be able to help you.

Drivers and employers that may be covered by FMCSA regulations

Many drivers and employers may be subject to the FMCSA’s regulations covering the use of drugs and alcohol by commercial drivers, including the following:

  • A person or entity that leases or owns commercial vehicles
  • A person or entity that assigns drivers to operate commercial vehicles
  • For-hire motor carriers
  • Private trucking carriers
  • Local, state, and federal governments
  • Civic organizations that transport people
  • Bus drivers
  • Truck drivers
  • Churches

FMCSA and Pennsylvania blood-alcohol limits

Under the FMCSA regulations for commercial drivers, the drivers have a legal limit of 0.04% blood alcohol concentration.

By contrast, other motorists have a legal limit of 0.08% BAC. The FMCSA rules also state that commercial drivers are not allowed to operate commercial vehicles within four hours of drinking alcohol.

Under 75 Pa.CSA § 3802(f), Pennsylvania prohibits commercial drivers from operating, driving, or having actual physical control of a commercial truck’s movement when they have a BAC of 0.04% or higher when they are tested within two hours of driving the trucks.

If you are a school bus driver, the limit is even lower at 0.02% BAC, which may be equivalent to a single beer.

Alcohol and drug testing for commercial drivers

Commercial drivers may have requirements to undergo random tests for alcohol. They may also be required to submit to a test following an accident, and when there is a reasonable suspicion that the driver has been drinking or using drugs.

Commercial drivers may also have to submit to tests after an alcohol policy violation as a condition of returning to their jobs. For drugs, commercial drivers may also have to submit to drug testing as a condition of employment.

Under FMCSA regulations, commercial drivers who refuse to submit to blood alcohol tests when they are pulled over on suspicion of DUI may face harsher penalties.

Penalties for a commercial DUI

CDL drivers who are charged with DUIs in Pennsylvania while they are on the job will face similar procedures as other DUI defendants other than having a lower threshold for the BAC level.

However, a DUI conviction for operating, driving, or being in actual physical control of a commercial vehicle while you are under the influence can cause you to lose your license for longer than for a general impairment DUI.

As a commercial driver, the suspension might mean that you will lose your job.

Under 75 Pa.C.S.A. § 1611(a), a first DUI conviction by a CDL driver will result in a one-year disqualification of your CDL license. If you were transporting hazardous materials or were driving a bus with 16 or more passengers, a first offense can result in a license disqualification for three years.

You will also be subject to a three-year disqualification if you were transporting hazardous materials or driving a bus for a refusal to submit to a test. If you have two convictions for a DUI, you may be disqualified from driving a commercial vehicle or a bus for life.

Because of the high stakes that are involved with DUIs when you have a commercial driving license, it is important for you to get legal help. If you plead guilty to the charges, you may lose your license and your livelihood.

In addition, a conviction will subject you to the other penalties and fines of a DUI.

Your attorney may fight the charge against you in an effort to protect your license and your job.

Your attorney might also be able to secure a plea agreement to a different charge instead of a commercial DUI.
