The FMCSA provides the most recent rules and regulations for drivers and vehicles online. While there are a number of these rules and regulations, as of 2015, common topics are: hours of service, medical, drug and alcohol testing, and hazardous materials, says the FMCSA. Drivers who operate a property-carrying vehicle or passenger-carrying vehicle must comply. The FMCSA sets specific guidelines for what constitutes a commercial vehicle and the applicable driving limits. For example, as of April 2015, property-carrying drivers can drive a maximum of 11 hours after 10 consecutive hours of rest, says the FMCSA.

Another important regulation dictates medical requirements for commercial drivers. Interstate commercial vehicle drivers must have a current Medical Examiner's Certificate in order to drive, explains the FMCSA. In 2015, pre-employment and post-accident drug testing is also necessary, according to the FMCSA. A CDL driver must receive a negative result in order to operate a commercial vehicle.
