Federal Regulations
Part 383:  CDL Standards, Requirements & Penalties

This section deals with the some of the specific requirements necessary to become a driver of commercial vehicles.   You'll find more information at the FMCSA website of course. http://www.fmcsa.dot.gov/rulesregs/fmcsrhome.htm

Although in most States, you may drive a vehicle at the age of 16, the requirements are a bit different for commercial vehicles.  You may possess a commercial drivers license and operate a commercial vehicle within the boundaries of some States at the age of 18, but to drive inter-state or from state to state, you must be at least 21 years of age.

You must be able to read, write and speak the English language well enough to take instructions from highway signs, complete required reports and to converse with officials.

You must be physically able to safely operate the type of vehicle you are driving.  That means you must be able to perform pre-trip inspections, make sure your loads are secure, etc.  Drivers must pass a complete physical examination every two years.

You must have the proper training and/or experience to safely operate the vehicle that you will be driving.

All drivers of commercial vehicles must carry one and only one commercial driver's license, issued by their home State. 

A license is issued after extensive knowledge and skills tests are successfully completed.

There are certain physical qualifications and examinations necessary to perform the duties of driver of a commercial vehicle.
An individual:
     1.  Must not have a loss of foot, leg, hand or arm, unless a waiver has been granted.
     2.  Must not have an impairment of hands or fingers that interferes with prehension or power grasping.
     3.  Must not have an impairment of an arm, foot or leg which interferes with the ability to perform normal tasks associated with operating a commercial vehicle, unless a waiver has been granted.
     4.  Must not have an established medical history or clinical diagnosis of diabetes mellitus, requiring insulin for control.
     5.  Must not have an established medical history or clinical diagnosis of heart disease such as myocardial infarction, angina pectoris, thrombosis, or any other disorder that could result in sudden collapse or heart failure.
     6.  Must not have an established medical history or clinical diagnosis of respiratory dysfunction that could result in lack of control or inability to operate a vehicle safely.
     7.  Must not have an established medical history or clinical diagnosis of high blood pressure, arthritis, or other condition that could interfere with safe operation of a commercial vehicle.
     8.  Must not have an established medical history or clinical diagnosis of epilepsy or any condition that could result in loss of consciousness and loss of control of a vehicle.
     9.  Must not have an established medical history or clinical diagnosis of mental impairment that could interfere with the safe operation of a commercial vehicle.

Complete physicals and medical examinations are required on an annual basis to ensure the continued health of the driver and his/her ability to safely operate a commercial vehicle.

Hazardous materials drivers must pass additional tests, exhibiting knowledge of, and the safety and handling of such materials.

Remember 9-11-2001?   Because of a new awareness of terrorism and the lengths to which terrorists will go, the Federal Government is developing new regulations concerning background checks for commercial drivers transporting hazardous materials.  The DOT is in the process of developing rulemaking to prohibit states from issuing or renewing a commercial driver's license with an endorsement to operate a motor vehicle transporting hazardous material unless the Department of Justice has first conducted a background check on the applicant.   Once the individual's investigation has been completed, the DOT must then determine that the applicant does not pose a security risk warranting denial of the license.   This rulemaking is required by section 1012 of the U.S. Patriot Act and will be accessible to read at the FMCSA website.
