Attending traffic school is always beneficial, but it is not likely to help commercial drivers avoid a suspension or revocation of the CDL. In New York, a DMV-approved driving course will increase the point threshold needed for a suspension (it does not actually eliminate the points). In NY and most other states, traffic school can also help slightly reduce one’s personal (non-CDL) auto insurance rates. However, federal CDL requirements look only at the number of convictions within a 3-year period. Since traffic schools do not change or eliminate those convictions, it is not likely to help commercial drivers avoid a suspension of the CDL.
