Which of the following is a condition requiring a chauffeur's license revocation?

The condition that warrants the revocation of a chauffeur's license is the failure to stop at an accident scene. This is considered a serious offense because it implies a disregard for safety and legal responsibilities. When a driver is involved in an accident, they have a duty to stop, assist any injured parties, and provide necessary information to authorities. Failing to stop can lead to severe legal consequences, including revocation, as it shows negligence and can endanger lives.

While involvement in a minor accident, driving with a suspended license, and parking violations can carry penalties, they do not typically lead to an automatic revocation of a chauffeur's license in the same way that leaving the scene of an accident does. Each of these situations may have specific consequences, but not all are as egregious as failing to fulfill the legal obligation to stop at an accident.
