According to the PennDOT Driver and Vehicles Services commercial driver (CDL) fact sheet a disqualification can result from a single conviction for a MAJOR OFFENSE, an accumulation of SERIOUS TRAFFIC OFFENSES or for other specific violations, i.e. violations of railroad-highway grade crossings.

Major violations include offenses such as driving under the influence of alcohol or controlled substance, leaving the scene of an accident, etc. Serious offenses include exceeding maximum speed limit 15 mph or more, recklessly driving, making improper or erratic traffic lane changes and following the vehicle ahead too closely.

If you are convicted of any 2 of these serious traffic offenses within a 3 year period, you will be disqualified from driving a CMV for 60 days. If you are convicted of 3 or more serious traffic offenses within a 3 year period, you will be disqualified from driving a CMV for 120 days. Most of these violations must occur in a CMV to count as a STO. However, there are some exceptions as noted below.

You would need to check with PennDOT to see if your New York offenses count as serious or not. It would appear from the descriptions you have given in your questions they likely will be considered serious and thus result in a disqualification of your ability to drive a commercial motor vehicle for a certain time period.

As you are likely aware both New York state and Pennsylvania are both members of the drivers license compact (DLC) and thus NYS will report these violation convictions back to PA. Normally for regular driver's (non-CDL holders) they do not place minor out of state moving violations on a driver's license however they do add the violations if you are a CDL holder. For CDL holders PennDOT treats out-of-state violations as if they occurred in Pennsylvania.

For more information you can read the PennDOT fact sheet we referred to here and contact PennDOT directly to find out what penalties they are likely to hand you for your NYS moving violations. Since CDL holders are held to higher standards of driving then non-CDL motorists it is very likely your license will be suspended in both New York and Pennsylvania however you and/or your lawyer will need to find out for certain what penalties both states will place on your for the 3 offenses you were cited for, if you are convicted.
