Other CDL Rules

There are other federal and state rules that affect drivers operating CMVs in all states. Among them are:

  • You cannot have more than one license. If you break this rule, a court may fine you up to $5,000 or put you in jail and keep your home state license and return any others.
  • You must notify your employer within 30 days of conviction for any traffic violations (except parking). This is true no matter what type of vehicle you were driving.
  • You must notify your motor vehicle licensing agency within 30 days if you are convicted in any other jurisdiction of any traffic violation (except parking). This is true no matter what type of vehicle you were driving.
  • You must notify your employer within two business days if your license is suspended, revoked, or canceled, or if you are disqualified from driving.
  • You must give your employer information on all driving jobs you have held for the past 10 years. You must do this when you apply for a commercial driving job.
  • No one can drive a commercial motor vehicle without a CDL. A court may fine you up to $5,000 or put you in jail for breaking this rule.
  • If you have a hazardous materials endorsement you must notify and surrender your hazardous materials endorsement to the state that issued your CDL within 24 hours of any conviction or indictment in any jurisdiction, civilian or military, for, or found not guilty by reason of insanity of a disqualifying crime listed in 49 CFR 1572.103; who is adjudicated as lacking mental capacity or has been involuntarily committed to a mental health facility as specified in 49 CFR 1572.109; or who renounces his or her U. S. citizenship;
  • Your employer may not let you drive a commercial motor vehicle if you have more than one license or if your CDL is suspended or revoked. A court may fine the employer up to $5,000 or put him/her in jail for breaking this rule.
  • You are not allowed to hold a mobile telephone to conduct a voice communication or dial a mobile telephone by pressing more than a single button when driving.
  • You are not allowed to send or read text messages while driving.
  • You must be properly restrained by a safety belt at all times while operating a commercial motor vehicle. The safety belt design holds the driver securely behind the wheel during a crash, helping the driver to control the vehicle and reduces the chance of serious injury or death. If you do not wear a safety belt, you are four times more likely to be fatally injured if you are thrown from the vehicle.

All states are connected to one computerized system to share information about CDL drivers. The states will check on drivers' accident records to be sure that drivers do not have more than one CDL.
