Federal serious-violation categories
Current federal regulations list categories that include certain convictions for speeding fifteen miles per hour or more above the regulated or posted limit, reckless driving, specified lane or following violations, and specified traffic-control violations connected with a fatal accident.
The federal table also identifies certain CDL class, possession, and endorsement violations committed while operating a commercial motor vehicle.
Repeated qualifying convictions
The current federal table generally describes sixty-day and one-hundred-twenty-day commercial disqualifications for specified combinations of qualifying convictions from separate incidents within three years.
Commercial and personal vehicles
The federal table treats commercial-motor-vehicle and noncommercial-vehicle convictions differently. A qualifying personal-vehicle conviction counts only under specified circumstances involving the noncommercial driving privilege.
